After establishing this database, they discovered the acetyl-CoA pathway was by far the most common; as such, a more detailed mechanism of this pathway can be seen below. [6], Isoamyl acetate occurs naturally in the banana plant[7] and it is also produced synthetically. 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. IUPAC Standard InChIKey: CFNJLPHOBMVMNS-UHFFFAOYSA-N Copy CAS Registry Number: 540-18-1 Chemical structure: This structure is also available as a 2d Mol file; Other names: Butyric acid, pentyl ester; n-Amyl butyrate; n-Pentyl n-butyrate; Amyl butyrate; Pentyl butanoate; Pentyl butyrate; 1-Pentyl butyrate; n-Pentyl butanoate; UN 2620; n-Amyl n-butyrate; Amyl butanoate; n-Pentyl butyrate Established in 1913 as a small grocery store, in its over 100 years of activity ECSA Chemicals has become one of the most important Swiss-owned distributors of chemical products.

Compared to the batch reaction with only 60% conversion of n-butanol, the reactive distillation column can improve the conversion ofn- butanol (up to 93.6%) and the lipase-loaded packing storage in the reaction system at 70 C for 120 days verified that the conversions could still reach 72.5%.
