MEANS FOR SOAP STOCK RECYCLING – TECHNOGENIC WASTES OF FAT-PROCESSING INDUSTRY

Abstract

The paper present results concerning determination of quantitative composition of soap stock while using methods for centrifugal concentration and fractional separation. Gas chromatography analysis data on soap stock are obtained in the paper. An isolation of higher fatty acids have been executed and their sodium, potassium and zinc salts have been obtained in the research. Dependence of the surface tension of potassium soap water solutions on concentration has been studied and potassium soap surface activity has been determined in the paper.
