Description

one

The invention relates to an improved method for producing a composition for fatting skin and fur, and may find use in enterprises producing fatty agents.

The purpose of the invention is to improve the quality of the finished product.

The essence of the invention lies in the fact that according to the method of obtaining the composition for fattening the skin and fur by oxidizing the fat with oxygen of the air at elevated temperature

- in the presence of a catalyst, a metal salt of variable valence of a polyunsaturated fatty acid and sulfonation of the oxidized mixture with sodium bisulfite in the presence of an emulsifier at an elevated temperature, a cobalt or manganese salt of the fatty acid mixture of the fraction is used as a catalyst and the process is carried out at 0 ° C, 0001-0,001 wt.% In terms of metal.

Example 1. Fish oil is added to a chopper equipped with an agitator and air bubbler, 0.0001% by weight, calculated on cobalt metal, cobalt salt of a mixture of polyunsaturated fatty acids of Cjo-C i fraction, dissolved in fish oil and heat the mixture to 50 ° C. With constant stirring, air is bubbled through the reaction mixture for 2 hours. Then, 0.5% by weight of the fat of the emulsifier based on ethoxylated higher fatty acids is mixed for 15 minutes and 30% by weight of the aqueous solution of sodium bisulfite (37%) is added. The process of sulfonation is carried out with continuous stirring for 3 hours.

Examples 2,3. The results of the experiments are summarized in table. one.

In tab. 2 presents the qualitative characteristics of the fattening pastes obtained in examples 1-3.

Carrying out the process according to the proposed method allows to obtain a ready-made composition for greasing the skin of fur, which is a moving mass of orange-red or orange-brown color, high quality.

forming stable emulsions in water and in electrolyte solutions.

Carrying out the process at a low temperature while maintaining the rest of the process parameters at optimal values results in an unstable emulsion, as well as a significant increase in the duration of the sulfonation process (3 times as compared with Example 1), and the same increase in the duration of the process catalyst up to 0.00005% to fat ratio (in terms of metal), while in the latter case, a greasing paste that forms an emulsion is not achieved.

one

An increase in the concentration of the catalyst, although it leads to a certain reduction in the duration of the process, but practically does not affect the quality of the resulting paste and, therefore, is not economically feasible.

Carrying out the process at a higher temperature causes a darkening of the fattening paste, as a result of which it becomes unsuitable for the fattening of furs with bright colors.

The proposed method of obtaining a composition for fattening skin and fur as compared with the known one allows reducing energy consumption by 2-2.5 times due to lowering the process temperature, reducing catalyst consumption by more than 100 times, improving the quality of the composition for fattening skin and fur by increasing emulsion stability and lighter pastes.
