FIELD: metallurgy.
SUBSTANCE: waterless soapy-glycerine concentrate, received during treatment of sunflower oil by alkaline in methyl alcohol, it is treated by boric acid. Boric acid is introduced in amount 5-15% of glycerine mass, contained in soapy-glycerine concentrate. Treatment of soapy-glycerine concentrate by boric acid is implemented at temperature 120-140°C during 30-60 minutes.
EFFECT: reduction of boric acid consumption, raw materials base widening for receiving of rolling emulsol ensured by usage of waste products, improvement of antifriction properties.
