Our Pharmaceutical offerings continue to expand, still anchored by the Boronic Derivatives that meet the demands of Suzuki coupling reactions. In order to confidently identify the enzymes involved in the butyrate synthesis pathway(s), Vital, Howe, and Tiedje used comprehensive screenings of established gene libraries, including the Integrated Microbial Genome (IMG) platform, to detectpotential biosynthetic genes among published genomes of gut microbes; they established a gene catalogue containing 3,055 entries from 225 organisms.

Epub 2007 Mar 20. the 132nd, light daily use chemicals office of Ministry of Light Industry (87) " literary composition], the butyric acid of special class national enterprises and alcoholic acid unit consumption standard are respectively 0.966 ton/ton and 0.551 ton/ton, the butyric acid of class-one national enterprises and alcoholic acid unit consumption standard are respectively 0.976 ton/ton and 0.568 ton/ton, the butyric acid of second-class state enterprise and alcoholic acid unit consumption standard are respectively 1.015 tons/ton and 0.612 ton/ton, and butyric acid of the present invention and alcoholic acid average quantity used in unit volume blasted only are 0.8102 ton/ton and 0.4860 ton respectively); (3) production cost reduces about 25%; (4) equipment capacity (reactor with unit volume calculates) improves about 8 times; (5) facility investment reduces about 40%; (6) wastewater discharge reduces about 90%; (7) quality product reaches U.S. FCCIII standard. 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. Some critically evaluated data
