The process of obtaining of aliphatic dibasic esters from dicarboxylic acids and C4-C5 alcohols in the presence of perfluoro(4–methyl–3,6–dioxaoctane)sulphonates of different metals has been researched. For the comparative estimation of catalysts their concentration was chosen identical and of such value that the rate of the process was limited exactly by the rate of chemical reaction. The dependences of technological characteristics of esterification process on catalyst nature and concentration and on reagents nature have been determined. High activity of the investigated catalysts has been found out, which is probably caused by the synergetic effect of metal cation and perfluoroic fragment, which provides decreasing of electron density on metal ion and at the same time good solubility of catalyst in the substrate, thus providing its high active concentration.
