The invention relates to a derivative sulfinol acid and their preparation and application in various fields.

As you know, Sultanova acid, H2SO2that is one of the strongest known reducing agents. Free Sultanova acid unstable. Accordingly, it is only available commercially in the form of its stable and accordingly Inovas acid: 1. Dithionite sodium (bleaching of the fibers in the manufacture of paper, kubova dyeing and bleaching of textiles, bleaching mineral raw materials, recovery of heavy metals in industrial drains).

2. The dihydrate of formaldehydeinduced sodium (mordant dyeing of textiles, bleaching of textiles, restoration socialization when emulsion polymerization, recovery of heavy metals, pharmaceutical industry).

3. Formamidinesulfinic acid (bleaching of the fibers in the manufacture of paper, bleaching of textiles).

4. Formaldehydeinduced zinc (mordant dyeing and bleaching of textiles).

All of the above derivatives sulfinol acid used in the form of aqueous solutions or dispersions. In the aquatic environment dithionite sodium and formamidinesulfinic alkali metal - free formamidinesulfinic acid is not really soluble in water and, in its acidic form has only very weak restorative effect is stable over a short period of time. As a result, even at room temperature they exhibit excellent resilience and provide an excellent whitening effect on the fibers. Water composicin months. As a result both of these formaldehydeinduced are inherent restorative effect at temperatures above 90oCelsius. In strongly alkaline or acidic medium or in the presence of a suitable strong oxidizing agents both formaldehydeinduced undoubtedly also have a restorative effect at temperatures below 90oC. It is the specific property of formaldehydefree, namely the manifestation of a very uniform and easily controlled restorative actions at temperatures between 5oWith the 90oWith led to their application when initiated by a free radical emulsion polymerization. Here formaldehydeinduced use in various emulsion polymerization systems. When cold the receiving BSC (best choice rubber) initiate polymerization using organic peroxides. However, at low temperature polymerization of about 5oWith organic peroxides not decompose into free radicals. Cleavage of peroxides should be initiated by catalytic quantities of salts of iron(II). Iron from the state of oxidation of the two turns in the oxidation state of three, which makes him unsuitable ones of iron (II) - if this continues cleavage of the peroxide and the initiation of free radicals. In other emulsion polymerization systems, peroxide compounds such as hydrogen peroxide or peroxodisulfate use as compounds that form free radicals. To increase the rate of formation of free radicals again using reducing agents. As examples can be mentioned formaldehydeinduced, bisulfite, ascorbic acid, isoascorbic acid and erythrobic sodium. Formaldehydeinduced, in particular formaldehydeinduced sodium, proved to be particularly effective and valuable recovery agents. However, during the recovery process, formaldehydeinduced remove formaldehyde. Plastic or polymer dispersion, which must not contain formaldehyde, polimerizuet using any of bisulfite, ascorbic acid, isoascorbic acid or ritrovata sodium. So as not containing formaldehyde reducing agents are weaker reducing agents, it should be noted as a deficiency of less than a full course of polymerization compared to formaldegidsoderzhaschimi. Kromom yellowing of the polymer.

The purpose of this invention is to provide new derivatives sulfinol acids, chemical properties similar as possible, the properties of formaldehydeinduced, but not eliminate formaldehyde during or after application.

Suddenly, now found that this object is achieved derivatives sulfinol acid of the type described below in more detail.

Thus, in the present invention developed derivatives sulfinol acid of the formula (I):where M represents a hydrogen atom, ion, ammonium ion is monovalent metal or the equivalent of a divalent ion of a metal of groups Ia, IIa, IIb, IVa or VIIIb of the Periodic Table of Elements; R1is HE or NR4R5where R4and R5independently of one another are N or C1-C6-alkyl; R2represents H or alkyl group; R3is the SOOMA, COOR4where M, R4are as defined above, or their salts.

For the purposes of this invention the expressions listed below have the following meanings: alkyl represents a linear or branched alkyl group, which preferably is util, tert-butyl, n-hexyl, etc.

The same applies to the alkyl groups in O-alkyl.

Alkenyl represents a linear or branched alkeneamine groups, which preferably have 3 to 8 carbon atoms, in particular 3 to 6 carbon atoms. Preferred alkenylphenol group is an allyl group.

Cycloalkyl is, in particular, With3-C6-cycloalkyl, cyclopentyl and cyclohexyl is particularly preferred.

Halogen is F, C1, Br and I, preferably CL and Br.

M preferably represents an ammonium ion, alkali metal ion or an equivalent ion alkaline-earth metal or zinc ion. Suitable alkali metal ions are in particular the ions of sodium and potassium. Suitable ions of alkaline-earth metal are, in particular, ions of magnesium and calcium.

R1preferably represents a hydroxyl or amino group.

R2preferably represents a hydrogen atom or alkylene is defined above).

The preferred embodiment include compounds of formula (I), where M represents an alkali metal ion or an equivalent ion alkaline-earth metal or she is zinc; R1represents a hydroxyl or amino group;
R2represents H or alkyl; and
R3is the SOOMA or COOR4where M is H, alkali metal ion or an equivalent ion alkaline-earth metal and R4represents N or C1-C6-alkyl.

The new compounds are obtained from dithionite salts, mainly salt has a cation, which is also desirable in connection sulfinol acid. Dithionite salt is put into engagement with the corresponding aromatic aldehyde to obtain such compounds, where R2represents unsubstituted or substituted aryl radical and R3represents a hydrogen atom. This interaction can be illustrated by the reaction of dithionite sodium and 2-hydroxybenzaldehyde the following reaction equation: equivalent ion alkaline-earth metal or zinc ion;
R1represents a hydroxyl or amino group;
R2represents H or alkyl; and
R3represents the SOOMA and the>represents a C1-C6-alkyl.

R3represents a hydrogen atom.

The new compounds are obtained from dithionite salts, mainly salt has a cation, which is also desirable in connection sulfinol acid. Dithionite salt is put into engagement with the corresponding aromatic aldehyde to obtain such compounds, where R2represents an unsubstituted or substituted aryl radical and R3represents a hydrogen atom. This interaction can be illustrated by the reaction of dithionite sodium and 2-hydroxybenzaldehyde the following reaction equation:

All other compounds of formula M is produced by interaction dithionite salts with the corresponding 1,2-dicarba establet a, in particular, Glyoxylic acid or the corresponding catasetinae and their esters. The interaction can be illustrated by the example of dithionite sodium and Glyoxylic acid by the reaction equation below:

Communication is usually carried out in aqueous medium in the presence of a base. The aquatic environment may also include water-soluble organic solvents, such as methanol, ethanol, isopropanol, etc. as the bases can be used, in particular, hydroxides of alkali metals and hydroxides of alkaline-earth metals. The reaction is usually carried out at room temperature; heating the reaction mixture is usually not necessary since the reaction is exothermic. The desired product usually precipitates from the reaction mixture or it can be planted by adding a water-soluble polar organic solvents, such as methanol, ethanol, isopropanol, acetone, and so on, the Final product is in the form of a salt, which may, if desired, be converted into the free sulinowo acid by acidification or treatment of acidic ion exchange resins.

In addition, the product is usually obtained in the form of a mixture with the corresponding sulfite metal New connections can be separated from other components by conventional means, for example by recrystallization from water or aqueous alcohol.

For practical application it is not necessary to separate from the other components. On the contrary, it was found that these related components even enhance the effect of new compounds. Thus, the invention also provides appropriate mixture of these components. For these purposes, the sulfite metal may be present in amounts up to 40% and sulfonic acid up to 60%. The water content can reach 30%.

New connections are reducing agents. Whose remedial action is comparable with the action of formaldehydeinduced. However, they have the advantage that before, during and after use, they do not eliminate formaldehyde. Thus, the new compounds are preferably used in those areas where it is undesirable formaldehyde emissions. For example, they can be used as reducing agents in printing on fabric, in particular when mordant dyeing of textiles, bleaching fabrics or VAT dyeing, or as reducing agents for bleaching of minerals, such as kaolin and so on, and fibers, for example tsellyuloznoi together with peroxide initiators for carrying out the polymerization at a lower temperature. For this purpose, if desired, sulfinate acid may also be used together with the oxidizable metal ions, such as Fe2+, Mn2+and so on, These metal ions mainly used as counterions for connections sulfinol acid, i.e., M=Fe2+, Mn2+and so on

To apply the new connection is usually introduced into the formulations together with conventional additives and auxiliary substances. In this respect, there are no specific limitations, only do not use regenerative connection.
