Abstract

The present invention relates to a method for producing alkyl lactate directly from ammonium lactate generated in a fermentation process. In detail, the present invention relates to a method for producing alkyl lactate directly from ammonium lactate, comprising a first step of producing a mixture comprising an aqueous solution of ammonium lactate generated in a fermentation process and trialkyl phosphate-based organic solvent extractants, and heating the mixture to prepare lactic acid; and a second step of performing an esterification reaction between the lactic acid prepared in the first step and alcohol to prepare alkyl lactate. According to the method of the present invention, a pretreatment process such as the addition of sulfuric acid required for preparing lactic acid is eliminated, and an esterification reaction between lactic acid and alcohol is performed simultaneously with the preparation of lactic acid in order to produce alkyl lactate, thereby producing alkyl lactate in an easier manner than conventional processes for producing alkyl lactate from lactate salts generated in a fermentation process, and, during an esterification reaction with lactic acid, effectively separating, from lactic acid or alkyl lactate contained in an organic solvent, water to be derived as a by-product, such that the reaction speed and yield rate can be improved and high-efficiency and high-purity alkyl lactate can be produced.
