PROCESS FOR PREPARING ALKYL LACTATE FROM FERMENTATION-DERIVED AMMONIUM LACTATE

摘要

PURPOSE: A method for directly preparing alkyl lactate from ammonium lactate is provided to improve reaction rate and yield without a pretreatment process. CONSTITUTION: A method for directly preparing alkyl lactate from ammonium lactate comprises: a step of mixing an ammonium lactate solution and trialkylphosphate organic solvent extract to obtain a mixture and heating; and a step of performing esterification on lactic acid and alcohol to prepare alkyl lactate. The trialkylphosphate organic solvent extract is a trialkylphosphate organic solvent containing alkyl group of C1-C20.
