We strive every day to find the best products that satisfy your needs as quickly as possible. The present invention is explained in detail by embodiment below in conjunction with accompanying drawing; 1. it is raw material that the present invention for preparing burden adopts butyric acid (content 9798%) and ethanol (content 9293%), with sulfuric acid is catalyzer, the bed material proportioning is a butyric acid: ethanol=3.05.0: 1 (mol ratio), dripping the material proportioning is butyric acid: ethanol=0.851.05: 1 (mol ratio). We employ our five senses to do our job well. Pentyl butyrate, also known as pentyl butanoate or amyl butyrate, is an ester that is formed when pentanol is reacted with butyric acid,[1] usually in the presence of sulfuric acid as a catalyst. Download Citation | Study on the synthesis of amyl butyrate catalyzed by solid superacid | Solid superacid SO42-/TiO2 has been prepared by a sol-gel method with titanium tetrabutoxide as precursor. This chemical is used as an additive in cigarettes. We continuously strive to advance our technology. . The time-on-stream study was carried out at optimum conditions resulting in gradual decrease in the activity of the catalyst. Reaction parameters such as temperature, molar ratio and feed rate were optimized for higher butyric acid conversion. Bianchi, F., Careri, M., Mangia, A., and Musci, M. 2007. Ethyl butyrate is a colourless transparent liquid, similar pineapple fragrance, and 120.6 of boiling points, fusing point-93.3 is soluble in organic solvents such as ethanol and ether, and is water-soluble hardly.It has an extensive use in that essence, food, medicine and chemistry etc. ), World Patent Index (WPI) and world patent abstract (WPA) before the present invention makes, still find no the production technique similar to the present invention by retrieval.About the more representational document of ethyl butyrate production technique, for example; " (institute of scientific-technical information of Ministry of Chemical Industry edits and publishes world's fine chemistry industry handbook, December nineteen eighty-two the 1st edition, 383 pages), " synthetic flavor handbook (light industry press, September in 1985 the 1st edition, 463 pages) in all introduced the synthetic method of ethyl butyrate, but how the water that generates in the esterification reaction process is removed, and esterification process is carried out continuously, all do not make reports in the above-mentioned document. Non-Discrimination | This chemical is used as an additive in cigarettes. Retention indices in the analysis of food aroma volatile compounds in temperature-programmed gas chromatography: database creation and evaluation of precision and robustness. Lett. 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. Because of its intense, pleasant odor and its low toxicity, isoamyl acetate is used to test the effectiveness of respirators or gas masks. And we custom manufacture new products according to customers needs, and serve good quality products and service. Ton ethyl butyrate surplus the employing the present invention of State-Owned Wujiang Perfumery has produced 550, nearly 4 years production practice prove that the present invention compared with prior art has the following advantages: (1) productive rate height (the butyric acid productive rate reaches 96.1%, improves about 20% than prior art); (2) raw material consumption is low (compares with the ethyl butyrate raw material consumption standard of national-level enterprise [selecting from " No. Learn more about Institutional subscriptions.

Together we forecast demand and match it with supply of aroma chemicals, essential oils and natural isolates & extracts. 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. with date before 31.12.1992 and still valid on 11.12.2001 (patent law change 1993).
