Abstract
Anion-active surfactants on the ground of sulpho derivatives of a mixture of fatty acids isolated from corn oil and individual linolenic acid were obtained. Physicochemical properties of surfactants and calcium salts synthesized on their ground have been defined. Research with thin (0.16–0.17 mm) films of petroleum on the surface of various waters (fresh, distilled, sea) has shown that these salts as 5 and 10 % solutions of ethanol possess good petroleum collecting and petroleum dispersing properties. It has been established that 0.025 and 0.05 % solutions of calcium salts are biodegradable.
