Study On Green Process Of Ethyl Lactate Synthesis By Catalytic Distillation

A new technique is introduced for the synthesis of ethyl lactate. Namely, under ion-exchange resin catalyst a process of catalytic distillation is applied in synthesis of ethyl lactate with lactic acid and ethanol. It is a new try for synthesis of ethyl lactate through catalytic distillation and is very important for the development of ethyl lactate industries if it will be a successful study.We selected ion-exchange resin as the catalyst of this experiment. Reactive kinetics using ion-exchange resin catalyst is experimentally determined, and the equation of the reaction rate is established. The conclusion is obtained by analyzing the experiment result: the esterification is second-order reaction, and the hydrolysis is zero-order reaction, so the model for reactive kinetics is obtained:where k+ = 0.06429
