Abstract

The esterification of waste glycerol from biodiesel production (WG) ore pure glycerol (PG) with Sylfat 2 were made by catalyst 3% titanium alcoholate (TiAl) for 3 h at 150°C. The quantity of glycerol in WG and the oleic acid (OA) in Sylfat 2 were made with UV-VIS spectra. There UV-VIS and FTIR spectra were shown. Some quantity of free acids was neutralized with methylamine ore with 25% water solution of NH₃ and was given FTIR spectra of obtained products. All investigations for characteristics of these products were made with standard method by four ball machine. From WG ore PG and Sylfat 2 were obtained the valuable friction modifiers, comparable with standard compounds.
