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.

The possibility of obtaining ketones with two long carbon chains in the process of long chain esters transformation was studied. The reactions were carried out over catalyst containing Fe, Si, Cr and K oxides in a standard flow system under atmospheric pressure in temperature range of 320-400°C and at load of 1.5 h1. n-Decyl n-decylate, n-butyl n-dodecylate and methyl n-dodecylate were used as substrates.
