Abstract
FIELD: greasing agents. SUBSTANCE: method involves oxidative sulfonation of natural lipids and their mixtures with sodium bisulfite in the presence of surface-active substances and cobalt nitrate and glycols addition (10-40% of natural fat mass) to reaction mass before sulfonation in order to stabilize sulfonation process. EFFECT: improved method of composition preparing.

Изобретение относится к способам получения жирующих средств для кожевенной и меховой промышленности. С целью стабилизации процесса сульфирования предложен способ получения состава для жирования меха и кожи, включающий окислительное сульфирование натуральных жиров и их смесей бисульфитом натрия в присутствии ПАВ и раствора азотно-кислого кобальта и введение в реакционную массу перед сульфированием гликолей в количестве 10 - 40% к массе натуральных жиров.The invention relates to methods for producing fatliquoring agents for the leather and fur industries. In order to stabilize the sulfonation process, a method is proposed for preparing a composition for fatliquoring of fur and skin, including oxidative sulfonation of natural fats and their mixtures with sodium bisulfite in the presence of a surfactant and a solution of cobalt nitric acid and introducing 10-40% by weight of glycols into the reaction mass before sulfonation natural fats.
