pentyl butyrate synthesis

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.

Genetic diversity of volatile components in Xinjiang Wild Apple (Malus sieversii). 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. As suppliers / distributors of ingredients to the fragrance and flavour industries, our goal is to provide high quality materials at competitive prices with an exceptional level of service.
