Hydrolysates of chromed waste as raw materials for the production of surfactants

Abstract

Hydrolysate of chromet waste obtained by biotechnology methods was modified by substuting primary -NH2 groups with chloroacetic acid, phtalic anhydride and bynzylchloride and oleyl chloride the surface activity of the resulting products was monitored. Only products modified by phtalic anhydride and bynzylchloride and oleyl chloride show sufrace activity comparable with current surface active matter. Owing to the relatively high hydrolysate. MW the yield of only around 13-24% is achieved.
