Download water 1.2 pyridine as tribochemical catalyst of 0.1 sunflower oil 0.5 as the hydrocarbon solvent used white spirit. Stearic acid and all liquid components of the system was stirred for 45 min and was heated to 55oC. During this time, all of stearic acid went into solution. After the specified time has introduced a metal-containing reagent, was resumed bead mill and implement specified in example 1, the monitoring process. The amount of metal-containing reactant molar ratio and stearic acid and the change in the degree of conversion with time is shown in table.1. Examples of the use of these suspensions salts discussed below.As can be seen from the table.1 (and it presents metal compounds all groups of the periodic system of elements), the process is almost insensitive to the nature of the metal not only in qualitative but also in quantitative terms. Insensitive he and the purity of the metal-containing reagent.The sensitivity of the process to the nature of the carboxylic acid, as well as to the purity cyclododecane raw materials is characterized by the data of examples 37-65.Examples 37-65. Labogena described in the examples 2-37. Content loading water 1.5 pyridine 0,16 fish oil 1 or industrial oils 5 (example 51). As the hydrocarbon solvent used heptane (example 39, 59), xylenes (examples 37, 46-48, 57), solvent (examples 43, 44, 52, 55, 61), oil (example 54), in other cases kerosene. The temperature of the process: 20oC (examples 39, 42, 43, 51, 53, 54, 59, 62, 63), 40oC (examples 44, 45, 55, 56, 64, 65) and 60oC (examples 37, 38, 40, 41, 46-50, 52, 57, 58, 60, 61). The duration of mixing before entering the metal-containing reagent was 60 min (examples 37, 38, 40, 41, 44, 46-50, 52, 55, 57, 58, 60, 61, 64), in other cases, 30 minutes the nature of the acid used, its amount, the molar ratio of the metal-containing reagent acid, the nature of the metal-containing reagent and the distribution of degrees of transformation in time is presented in table.2.As can be seen from the table.2, the nature of the acids in high-speed characteristics of the considered process is not playing not only defining, but in General any significant role. The same applies to the purity of the used acid. In contrast to the above, the nature of tribochemical catalyst plays a much greater and can say that the decisive role in the management of the considered process that you is agrusti and beads, the sequence of loading operations and monitoring process similar to that described in examples 37 - 65.

Role played by many nitrogen-containing compounds (inorganic and organic). Here are seen the following pattern:
the least effective catalyst is ammonia;
go to ammonium salts, and salts of nitrous and nitric acids soprovozh have the last catalytic properties;
in a series of primary, secondary and tertiary amines is increased catalytic properties;
amines acids are more effective catalysts than with primary amines.The positive effect from the use of this invention, consider the example of making a composition for the fatliquoring of leather the method according to the patent /8/.1. Getting fatten cited method is carried out by liquid phase air oxidation of a mixture of fat with oil in the presence of a catalyst: a mixture of copper, chromium and barium chloride salts of fatty acids. The specified catalyst was prepared by the method of metabolic decomposition and tribochemical interaction of oxides of copper, chromium and barium with acids of tall oil and kerosene as solvent. Technological sequence of operations the preparation of the catalyst in a known manner in comparison with declare shown in table. 4.As follows from the table. 4, when using the proposed method the number of operations upon receipt of the catalyst was reduced from seven to two, and the duration of the process 220 min to 30 min (i.e., more than 7 times). The efficiency obtained by the claimed method of the catalyst is not inferior efficiency katalizatoram full use of their thickening ability in the preparation of fattening compositions. The tests showed that the introduction of the composition for fatliquoring 5 oleate of aluminum allows you to completely eliminate this undesirable phenomenon of stratification oiling composition during prolonged storage. To enter tribochemical the oleate of aluminum in the composition for fatliquoring is extremely simple. For this purpose it is necessary to carry out the tribochemical reaction of obtaining aluminum soap directly in the presence of one of the components of the oiling composition components: fish oil, industrial oil, oil, etc. short duration of the process and the simplicity of its hardware design is practically not complicate the process of obtaining oiling.At the same time to solve the same task in a known manner, you must create a plot, equipped autoclave to obtain the sodium Soaps of fatty acids, the capacity to prepare an aqueous solution of aluminum salt, a reactor for carrying out the interaction of the above mentioned compounds, a filter system, a system for cleaning aluminum soap from water-soluble salts of sodium, drying to remove free moisture, the apparatus for dispensing aluminum soap and mixing indicates the final result.Finally, a simple way to enter into the composition for the fatliquoring of leather soap heavy metals can not only improve the physical properties of fattening compositions, but also to obtain compositions that improve the quality giovanny their skins. Test oiling composition initially containing in its composition 5 oleate of aluminum, in comparison with the composition without it showed that the samples of the oiling composition containing aluminum soap, allow to obtain much softer and filled the skin than control samples oiling.Sources of information
