Description

There is a known method of producing molds resistant to molds by introducing oxyphenyl in the form of a hot alcohol solution into the fat mixtures or emulsions used to fat the skins. The disadvantages of this method are the consumption of large quantities of alcohol, the deterioration of sanitary and hygienic working conditions as a result of vapor release, irritation: their mucous membranes, when dissolved oxydiphenyl in alcohol and unloading the skin after fattening, as well as some irritation of the skin covering of the hands of workers.

To eliminate the above disadvantages, it is proposed to introduce oxydiphenyl into the indicated fat mixtures or emulsions as a solution in synthetic fat. The latter is a product of the esterification with ethylene glycol of high molecular weight synthetic fatty acids, obtained by oxidation of paraffin with air.

Example. The composition of the mixture for fattening;

Synthetic fat-bo / o

Fish oil - 25%

Sulfonated fish oil-20Vo

Tar - 5%

Synthetic fat is heated with deaf steam in a blender equipped with a stirrer to 65-70 °, then the required amount of oxidiphenyl is introduced into the molten fat with mixing (at the rate of 2% of the weight of pressed skins). After p .-., Dissolving the oxidiphenyl completely, sulfated and unsulfated fish oil and tar are loaded into the mixer.

The temperature of a second fat mixture poured into a fat drum is 70 °. The mixture penetrates the skin well.
