Soc. H Technology, Office of Data Present domestic ethyl butyrate manufacturer adopts traditional single pot of esterification technique intermittently mostly, this technology is summarized as follows: adopting butyric acid and ethanol is raw material, in the preparation process of industrial ethyl butyrate, generally adopting materials such as benzene to form ternary azeotrope with ethanol, water, thus except that the method for anhydrating comparatively common; In the preparation process of edible ethyl butyrate, for pure property and the edible security that keeps product, do not allow material such as benzene to participate in the technological process, so the production of edible ethyl butyrate generally adopts butyric acid and excess ethanol to carry out esterification, after esterification finishes, add in the liquid caustic soda and nonesterified butyric acid, make it to generate Sodium propanecarboxylate and layering, ethyl butyrate thick ester in upper strata is after washing, rectifying, get the ethyl butyrate finished product, lower floor's Sodium propanecarboxylate solution adds the vitriol oil and carries out acidifying, dehydration after reclaiming ethanol, concentrating, thus the recovery part butyric acid.The subject matter that this traditional technology exists is; The butyric acid productive rate only is 7380%, the raw material consumption height, the production cycle is long, equipment capacity is low, facility investment is big, wastewater discharge is big etc. 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.
