Technological Aspects of Dicarboxylic Acids Esterification in the Presence of Aprotic Catalysts
The investigation results of the regularities of diesters of aliphatic dicarboxylic acids obtained in the presence of aprotic catalysts – Lewis acids – have been generalized. The effect of catalysts (metal salts) nature and concentrations, reagents nature and ratio, water content in them, as well as the influence of reaction temperature on the technological characteristics of esterification process have been determined. The technological aspects of the process have been examined in the presence of aprotic acids. The investigated catalysts may be reused in the technological process
