Abstract

Ethyl lactate has solvent properties of non-toxic, good solubility, less volatile and fruity smell, which is of great value and application prospect of "green solvents". Due to the characteristics of ethyl lactate, domestic and foreign scholars gradually focused on the development of more efficient and environmentally friendly method for preparation. Continuous fluidized catalytic distillation is a continuous, a highly efficient and environmentally friendly production method, in which the esterification of lactic acid and ethanol by super-acid cation exchange resin powder as a catalyst with the reaction flow. This paper aims to study synthesis of ethyl lactate by continuous fluidized catalytic and the comparison of continuous fluidized catalytic distillation and batch distillation to highlight former advantage. The results provide a reliable theoretical basis for continuous fluidized catalytic distillation to produce ethyl lactate, which plays a propulsive role in the food industry that has high purity requirements.
