Abstract

The invention relates to the microbiological industry and is intended to produce modified microbial fat, a component of lubricants in the production of chemical threads. The aim of the invention is to improve the quality of the fat base by improving the color and smell, which is achieved by the fact that microbial fat is subjected to treatment with hydrogen peroxide, taken in an amount of 10-20% by weight of microbial fat, and the treatment is carried out at 20-80 ° C within 4-8 hours. 1 tab.

Description

The invention relates to the microbiological industry and is intended for the production of modified microbial fat — a component of lubricants in the production of chemical filaments. The purpose of the invention is to increase ka-. the quality of the fatty base by improving color and odor .;

The method is carried out in the following way.

 ,

The product of microbiological paraffin waxing. of petroleum product, in particular microbial fat, is treated with hydrogen peroxide with stirring at 20 for 4-8 hours. Hydrogen peroxide can be added to microbial fat gradually 2.5 to 5% of its mass or the entire calculated amount

I

hydrogen peroxide - at the beginning of the reaction.

The amount of added hydrogen peroxide should be between 10 and 20 Z, based on the weight of the original microbial fat. This causes a change in the color of the product from black to light yellow with the disappearance of an unpleasant smell.

Example 1. 200 g of microbial fat with continuous stirring add 40 g of 30% hydrogen peroxide (200% to the mass of lipids), set the temperature of the reaction mass to 20 ° C and continue stirring for 8 hours. A fatty the basis of a light yellow, odorless color with a residual content of hydrogen peroxide of 0.27%.

Example 2. The raw materials, the sequence I and the processing conditions are similar to example 1, but the reaction is carried out at 6 hours and ne (L

with

Hydrogen rection is added in an amount of 10% by weight of microbial fat. The result is a fatty basis, the basis of a light yellow, odorless color with a residual content of hydrogen peroxide O, 24%.

Example Zo Sfye, sequence and processing conditions are similar to Example 1, but the reaction is carried out in the presence of hydrogen peroxide in an amount of 15% by weight of lipids at: 60 ° C for 4 hours. The result is a fatty, odorless, yellow yellow color with a residual hydrogen peroxide content of 0.20%.

The reaction time of the interaction of microscopic fat with hydrogen peroxide does not exceed 4–8 hours and is set, depending on the reaction temperature, the amount of hydrogen peroxide and the C-heat of reaction completion.

The duration of the process is less (E 4h, even at a temperature of 80 ° C and the highest concentration of hydrogen peroxide 20% does not lead to the clarification of microbial fat and odor disappearance, and the reaction time, which exceeds 8 hours, does not affect the result of obtaining a fatty base of lubricants.

Selected temperature range

vO

The reaction of 20–80 ° C is due to the fact that at a temperature below 20 ° C, the rate of clarification of microbial fat is insignificant, and at a temperature above 80 ° C, even in the absence of stirring of the reaction mass, abundant foam is formed and it flows out of the reaction vessel.

The amount of hydrogen peroxide used in the reaction from 10 to 20% by weight of microbial fat depends on the process temperature and the concentration (mass fraction) of the hydrogen peroxide contained in the product.

When hydrogen peroxide is added to less than 10% by weight of the original fat, it is not achieved complete clarification and reduction of unpleasant odor, and pre-.

The introduction of a 20% amount of hydrogen peroxide leads to abundant foaming, the release of the reaction mass.

When hydrogen peroxide is added, the free-radical mechanism interacts with lipids and free fatty acids, which are included in the composition of microbial fat, as a result of which the source microbial fat is completely eliminated and its bleaching occurs.

The results obtained from the examples and data in the table indicate that the product obtained according to the proposed method has a light yellow color and does not have an unpleasant smell, which improves its

20 commercial quality, and the addition of hydrogen peroxide, carried out at atmospheric pressure and heating the reaction mass at 20 - without the use of catalysts and process

25 filtering in devices of any type, allows to improve working conditions and improve safety.

The use of the product obtained by the proposed method allows JQ em to replace the expensive and very scarce whale (sperm) fat used in the manufacture of chemical filaments.
