ABSTRACT
This work presents a concept of waste technical fats processing into surfactants of gemini type based on the utilization of methyl esters of long chain fatty acids. The method of such esters ketonization has been elaborated upon. Ketones obtained in this way can be processed using reductive amination. Long chain amines can be used for the production of nonionic surfactants in the condensation with aldoses and hydrogenation or in condensation with oxidized sugars.
