The present invention relates to the use of phosphated 2-propylheptanol or phosphated of alkoxylate 2-propylheptanol as hydrotropes in aqueous alkaline solutions for alkoxylates C8-C18-alcohols containing 1-20 ethylenoxide links. The invention also relates to the phosphated alkoxylated 2-propylheptanolper seand alkaline cleaning composition, comprising a phosphated 2-propylheptanol and/or phosphated alkoxylated 2-propylheptanol as hydrotropes.

The ability of an aqueous solution evenly to cover the surface or so-called wetting ability is important for many applications. For example, the composition for cleaning hard surfaces benefit from a good wetting of the surface. Good wetting is also desirable for washing and processing methods sabrosky and mercerized. Nonionic surfactants, as is known, are a good wetting and often present in compositions for cleaning hard surfaces. Most often, the composition for cleaning hard surfaces also contains alkaline components. Many nonionic surfactants are insufficiently soluble in solutions with a high content of electrolytes, such as alkali and/or alkaline complexing agents and, with edutella, require the presence of hydrotropes to increase solubility. A number of hydrotropes for nonionic surfactants are described in various publications. Examples of such hydrotropes are ethanol, ecological sodium, coolcullen sodium, Alkylglucoside and phosphated alkoxysilane alcohols.

In U.S. patent 5145597 described alkaline detergent suitable for cleaning mechanical equipment. Data alkaline cleaners include hydrotap based on the ester of phosphoric acid and nonionic surfactant, but in your example is not specified, any ester of phosphoric acid was used.

In U.S. patent 4493782 described cleaning composition containing ethoxylated ester of phosphoric acid derived from alcohol, the alkyl chain of which has from 8 to 12 carbon atoms, and the alcohol amoxilbuy 2-4 moles of ethylene oxide (EO). This ether phosphoric acid is mixed with another ester of phosphoric acid derived from butanol + 2EO, the latter ester of phosphoric acid is added to stabilize the formulation.

U.S. patent 4137190 discloses a detergent composition comprising non-ionic surfactant and synergistic hydrotron mixture. In the working examples use a combination of P2O5-phosphated phenol + 6EO and PF is-phosphated butanol + 1EO or PFC-phosphated isoamyl alcohol + 4EO.

U.S. patent 3294693 reveals hydrotropic to solubilize polietilenoksidnoy nonionic surfactants in building solutions. Hydrotropes are surface-active materials, which contain more than 85% of primary esters of phosphoric acid. These esters obtained by reaction between PFC (polyphosphoric acid) and ethoxylated C6-C10the alkyl phenol or ethoxylated C10-C18-alcohol with 1-20 moles of EO. All the working examples used ethoxylates phosphated of the op.

The patent BE 632444 relates to alkaline detergents, which includes surface-active nonionic adducts of polyethylene oxide obtained by the accession of ethylene oxide to the alcohol, alkylamino or alkyl phenol, and hydrotap, which is a phosphate alkoxysilanes alkylphenol having 6 to 10 carbon atoms in the alkyl group or phosphate alkoxysilanes alcohol having 10 to 18 carbon atoms in the alkyl chain, and hydrotropic material contains 90% of the primary ester of phosphoric acid. In the working examples as hydrotropes used several phosphated alkoxysilane ALKYLPHENOLS, as well as phosphated dodecyloxy alcohol + 15EO and phosphated stearyl alcohol + 7,5EO to solubilize the op + 10 EO.

Esters of orthophosphoric acid, is received from the spirits which was amoxilonline with ethylene oxide in amounts up to 10, preferably 5 moles, are disclosed in patent EP-A-256427 as dispersing agents for pigments. Among these alcohols mentioned 2-propylheptanol.

Alkali metal salts of mono - and diesters of orthophosphoric acid, obtained from a number of alcohols are disclosed in patent CH-A-481953 as surface-active agents used in obtaining durable latex by emulsion polymerization vinylchloride monomers. Propylheptyl mentioned as one possible alkyl substituent in these phosphates.

However, there is still a need for new effective hydrotropic that are suitable for certain songs, because not all hydrotropic and nonionic substances are compatible to produce clear, stable solutions and optimal performance when considering the application. In particular, in some cases, alkaline solutions containing nonionic surfactant, derived from alkoxysilanes alcohol with branched alkyl, and hydrotap, will be separated upon dilution. An example of such alkoxylated alcohols are alkoxylated 2-propylheptanol, where tests showed that transparent and homogeneous alkaline concentrates containing acceleratedly adducts of 2-propylheptanol and hexing ICSID and/or activemanagement as hydrotropes, becomes turbid or exfoliate when they will be diluted to obtain ready-to-use solutions.

The present invention is to find new hydrotap, which is effective for obtaining a transparent homogeneous concentrated alkaline compositions containing alkoxylate C8-C18-alcohols containing 1-20 ethylenoxide links, especially alkoxylate 2-propylheptanol, and composition will remain homogeneous upon dilution, where the compositions have a good cleaning effect.

It has been unexpectedly found that the phosphated 2-propylheptanol or phosphated alkoxylated 2-propylheptanol where alkoxylate average includes 1-20, preferably 2-10, more preferably 2-6, more preferably 2-4, and most preferably 3 ethylenoxide link and 0-3, preferably 0-2 propylenoxide and/or butylaniline, preferably propylenoxide, link, is an effective hydrotap in alkaline aqueous solutions for alkoxylates C8-C18-, preferably C8-C12-alcohols containing 1-20, preferably 1-8, and most preferably 2-7, ethylenoxide links and 0-3, preferably 0-2, propylenoxide links, preferably to alkoxylated 2-propylheptanol according to the formula

<> where PO is propylenoxide group, EO represents ethyleneoxide group, a is a number 0-3, b is a number 1-8.

The invention also relates to aqueous cleaning solutions, including:

a) from 0.2 to 20%, preferably 2-10%, by weight of alkoxylate C8-C18-, preferably C8-C12-alcohol containing 1-20, preferably 1-8, and most preferably 2-7, ethyleneoxide units, preferably of alkoxylate 2-propylheptanol having the formula

where EO, PO, a, and b have the same meaning as described above;

b) 0.1 to 30, preferably 0.1 to 20, and most preferably 0.1 to 10% by weight of phosphated 2-propylheptanol and/or phosphated of alkoxylate 2-propylheptanol where alkoxylate average includes 1-20, preferably 2-10, more preferably 2-6, more preferably 2-4, and most preferably 3, ethylenoxide link and 0-3, preferably 0-2, propylenoxide link, preferably phosphated of alkoxylate according to the formula

where M represents H, a monovalent ion metal or R1R2R3R4N+where R1, R2, R3and R4represent H, an alkyl group with 1-4 carbon atoms or-CH2CH2OH, c represents the Wallpaper number 1-20, preferably 2-10, more preferably 2-6, more preferably 2-4, and most preferably 3, and

c) 0.05 to 40, preferably from 0.05 to 30, more preferably 0.05 to 20 and most preferably 0.05 to 15% by weight of alkali hydroxide and/or alkaline complexing agents; and they are homogeneous and stable upon dilution. The cleaning ability of these solutions is also very good.

Phosphated 2-propylheptanol or phosphated alkoxylated 2-propylheptanol can be obtained in various ways, the most common is the reaction of 2-propylheptanol or alkoxysilanes 2-propylheptanol with polyphosphoric acid or phosphorus pentoxide (P2O5).

In the method using polyphosphoric acid, the resulting mixture of products will mainly contain monocalciumphosphate ether 2-propylheptanol or alkoxysilanes 2-propylheptanol and only a small amount (<10%) dialkylphosphate ether. Always will be a fairly large amount of inorganic phosphate residues of polyphosphoric acid, such as orthophosphoric acid.

When the phosphate reagent is used P2O5and the molar ratio of P2O5and alcohol or alkoxycarbonyl alcohol is 1:3, the mixture of products will contain the AMB is approximately equal to the number monoalkylphenol ether and dialkylphosphate ether and only small amounts of inorganic phosphate residues. More alcohol or alkoxysilanes alcohol will give more diapir, and a smaller number will give more monoether. The person skilled in the art will know how to synthesize phosphate esters with certain quantities of mono - and dialkylphosphate esters. General description phosphate esters, see, for example, inAnionic SurfactantsVol. 7, Part II, pages 504-511 inSurfactant Science Series, edited by Warner M. Linfield, Marcel Dekker Inc., New York and Basel 1976. Alkoxylate spirits that need to be phosphotyrosine, can be any standard type, obtained using an alkaline catalyst such as KOH, or to treat type with a narrow distribution of molecular weight, obtained using catalyst narrow distribution, such as the acidic catalyst, Ca(OH)2or hydrotalcite.

Usually the reaction mixture obtained in both ways, before using neutralized organic or inorganic base. The base can be, for example, alkali hydroxide, such as sodium hydroxide or potassium hydroxide; ammonia, alkanolamine, such as monoethanolamine, triethanolamine or methyldiethanolamine; or alkylamine, such as triethylamine.

Monocalciumphosphate ether 2-propylheptanol or ethoxylated 2-propylheptanol has the formula

where M represents H, ion monovalent the metal or R 1R2R3R4N+where R1, R2, R3and R4represent H, an alkyl group with 1-4 carbon atoms or-CH2CH2OH, c represents a number of 0 to 20, preferably 2-10, more preferably 2-6, more preferably 2-4, and most preferably 3. The mixture of products obtained in the reaction of 2-propylheptanol or ethoxylated 2-propylheptanol with polyphosphoric acid, may also contain small amounts of products containing more than one phosphate level according to the formula

where n is 1-3 and M and c have the same significance as above.

In the case of ethoxylates containing smaller amounts ethylenoxide links, there is also a certain amount of methoxyethanol product due to this distribution ethylenoxide links. This methoxycarbonyl product will also propogation in the reaction with a phosphating agent and, therefore, the phosphate ester 2-propylheptanol will also be present in the reaction mixture resulting from the data above ethoxylates.

Dialkylphosphate ether 2-propylheptanol has the formula

where M and c have the same significance as above. The mixture of products obtained in the reaction of 2-propylheptanol or ethoxylated 2-is propylheptanol with P 2O5may also contain diphosphate ester according to the formula

where M and c have the same significance as above.

This type of diapir can hydrolyze with getting 2 moles of monoether.

2-Propylheptanol usually get way leading to small quantities of by-products such as 4-methyl-2-propylheptanol and 5-methyl-2-propylheptanol. These products or their ethoxylates also phosphatized during this process, and phosphate molecules will also be included in the resulting mixture of products.

The reaction mixture obtained by methods phosphating, usually used as such without any treatment, but as a mixture, and purified phosphate esters function as hydrotropes. In order to act as a good hydrotap, the mixture should preferably contain monocalciumphosphate esters, because they represent the best hydrotropic than dialkylphosphate esters. Preferably more than 60, more preferably more than 70, and most preferably more than 80% of the mixture should be monocalciumphosphate esters.

Phosphated 2-propylheptanol or phosphated alkoxylated 2-propylheptanol where alkoxylate average includes 1-20, preferably 2-10, more preferably 2-6, more preferably 2-4, and most is preferably 3, ethylenoxide link and 0-3, preferably 0-2, propylenoxide and/or butylaniline, preferably propylenoxide, link, described above, and methods for their production have been partially disclosed in the previously mentioned publications EP-A-256427 and CH-A-481953 for use as dispersing agents for pigments and as additives in the emulsion polymerization method, respectively. However, the phosphated alkoxylated 2-propylheptanol where alkoxylate average includes 2-4, preferably 3, ethylenoxide link, is particularly effective as hydrotap compared to other phosphated by alkoxylate 2-propylheptanol (see Table 1 in the Examples). Therefore, the invention also relates to alkoxylate phosphated 2-propylheptanol where alkoxylate average includes 2-4, preferably 3, ethylenoxide linkper seand by the way its receipt.

Alkoxylate C8-C18-alcohols can also 1-20 ethylenoxide links also contain 1-3 alkalinising link with 3-4 carbon atoms. Ethylenoxide links and propylenoxide and/or butylaniline links can be added randomly or in blocks. The blocks can be attached to alcohol in any order. Alkoxylate may also contain an alkyl group with 1-4 carbon atoms in the limit position. Preferably alkoxylate which contain 2-7 ethylenoxide links and 0-2 propylenoxide and/or butylaniline link.

Suitable alkoxylate, which can be used in cleaning compositions for cleaning hard surfaces, has the formula

where PO is propylenoxide group, EO represents ethyleneoxide group, a is a number 0-3, preferably 0-2, and b is a number from 1 to 8, preferably 2 to 7 and most preferably 3-6. When 2-propylheptanol contains the above-mentioned by-products, they will also be alkoxysilane and included in the resulting mixture of products. Cleaning concentrates obtained by use of phosphated alkoxylated 2-propylheptanol as hydrotropes for alkoxylated 2-propylheptanol are transparent and also stable upon dilution and cleaning compositions with these components show a good cleaning performance.

When the cleaning composition should be used for textile processing, such as washing, then alkoxylate a) should preferably include the number ethylenoxide links at the top of the range 1-20, for example 7-15 moles of EO per mole of C8-C18-alcohol.

Alkaline hydroxide in the composition is preferably a hydroxide of sodium or potassium. Alkaline complexing agents can be inorganic as well as organic. Tieckelmann inorganic complexing agents, used in alkaline compositions are silicate and phosphate alkali metal salts, such as sodium silicate, metasilicate sodium, sodium tripolyphosphate, sodium orthophosphate, sodium pyrophosphate and the corresponding potassium salts. Typical examples of organic complexing agents are aminophosphonate of alkali metals, organic phosphates, polycarboxylates, such as citrates; aminocarboxylate, such as nitrilotriacetate sodium (Na3NTA), sodium ethylenediaminetetraacetate (EDTA), diethylenetriaminepentaacetate sodium, 1,3-Propylenediamine sodium and hydroxyethylenediaminetriacetate sodium. The amount of alkali present in the composition depends on the application and on whether the composition is a concentrate or ready-to-use solution. In some applications, use of highly alkaline solutions, such as when Sharovka the concentration of alkali is about 4-6% by weight when using NaOH, and mercerized use approximately 20-26% by weight solution of caustic soda. The composition of the concentrate for cleaning vehicle typically contains from 6% to 15% by weight of alkali and/or alkaline complexing agents, and ready-to-use solution typically contains by weight from 0.2 to 5%. For washing, the amount of alkali and/or alkaline complexing agents less and Oba is but ranges from 3 to 10 mass% for the concentrate and 0.1-1% by mass in ready-to-use solution.

Concentrated compositions of the present invention are transparent and stable. The range of transparency seems to be acceptable in the temperature range between 0-40°C., preferably between 0-50°C. and most preferably between 0-60°C. It can be adjusted by changing the ratio of hydrotropes and nonionic surfactants. The concentrate typically contains 50-95% water by weight, more acceptable 70-90% by mass.

To obtain ready-to-use solution concentrates are diluted with water up to 1:40. Diluted solutions are also transparent and stable, but in some cases they can become somewhat murky, although they are still stable and not stratified. Ready-to-use solutions exhibit good cleaning properties. A typical formulation concentrate for cleaning the vehicle contains 3-5% by weight of a), 3-5% by weight of b) and 5-10% by weight of c), and ready-to-use recipe typically contains 0.2-1% by weight of a), 0.2 to 1% by weight of b) and 0.5-1% by weight of c).

The present invention is further illustrated by the following Examples.
