The object of the present invention is to provide that a kind of productive rate height, good economy performance, equipment capacity are big, good product quality and the reliable process for producing ethyl butyrate of stable operation. Because the short-chain fatty acids (SCFAs) produced by bacterial fermentation of carbohydrates in the human gut are so essential to many of the microbiota-mediated effects on human metabolism, we decided to investigate how SCFAs specifically, butyrate are synthesized by our microbial companions. 1. process for producing ethyl butyrate, be particularly related to the production technique of edible ethyl butyrate, it comprises that with butyric acid (content 9798%) and ethanol (content 9293%) be raw material, with sulfuric acid is catalyzer, ethyl butyrate production technique through processes such as batching, esterification, rectifying, it is characterized in that: determined bed material and dripped the rational proportion of expecting, the proportioning of bed material is a butyric acid: ethanol=3.05.0: 1 (mol ratio), and the proportioning that drips material is a butyric acid: ethanol=0.851.05: 1 (mol ratio); After treating in the bed material the basic esterification fully of ethanol, will drip and expect to add continuously in the reactor, simultaneously ethyl butyrate and the water form with binary azeotrope be steamed from cat head continuously; The binary azeotrope that steams shifts out the esterification system with the part of the whole and lower layer of water of the thick ester of upper strata ethyl butyrate after the condensation layering, another part of lower layer of water returns cat head as phegma.
