PROCESS FOR THE PREPARATION OF CARBOXYLIC ESTERS

摘要

The invention relates to a process for the preparation of carboxylic esters which involves operation of transesterification of fat and/or oil of biological origin as initial product by bonding with monobasic alcohol in the presence of catalyst with formation of glyceric phase and finished product part of which is directed to the operation of transesterification of the initial product. The operation of transesterification is carried out on the processing line of connected in series reactors, the initial product is subjected to pretreatment in supplementary reactor with glyceric phase removed from the reactors of the processing line. Thereafter glyceric phase from the supplementary reactor is directed to processing, and the reaction mixture from the supplementary reactor is directed to first reactor of the processing line.
