This article about an ester is a stub. .It is a colorless liquid that is only slightly soluble in water, but very soluble in most organic solvents. The objective of the invention is to realize by following method: with butyric acid (content 9798%) and ethanol (content 9293%) is raw material, with sulfuric acid is catalyzer, the bed material proportioning is a butyric acid: ethanol=3.05.0: 1 (mol ratio), and dripping the material proportioning is 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 is after the condensation layering, whole and part lower layer of water of the thick ester of upper strata ethyl butyrate (containing ester amount 9596%) is shifted out the esterification system, and another part of lower layer of water returns cat head as phegma, works to regulate gentle the replenishing in top and forms the required moisture of binary azeotrope; In whole continuous esterification operating process, control reflux rate and discharging speed, make the ethyl butyrate that shifts out the esterification system and the amount of water, substantially equate with the amount that drips the water that material contains in ethyl butyrate that esterification generates and water and ethanol raw material respectively, keep the composition of reactor internal reaction liquid constant substantially, form thus with water band ester, esterification is carried out continuously and stably; The thick ester of ethyl butyrate through light buck wash, after the rectification under vacuum, the ethyl butyrate finished product.
