醋酸仲丁酯的应用及其正丁烯法生产技术

THE APPLICATIONS OF SECBUTYL ACETATE AND ITS SYNTHESIS FROM NORMAL BUTENES

醋酸仲丁酯有多种用途 ,主要用作溶剂。醋酸仲丁酯以往由醋酸和仲丁醇反应合成 ,成本较高 ,逐渐被其他性能相近的产品取代。而利用正丁烯与醋酸反应直接合成醋酸仲丁酯 ,可以显著降低生产成本。本文介绍了醋酸仲丁酯的利用途径、醋酸仲丁酯的合成技术 ,特别是以正丁烯为原料合成醋酸仲丁酯的生产技术 ,分析了国内需求情况。

Secbutyl acetate had many uses and mainly used as solvent component. It used to be produced by the reaction between secbutanol and acetic acid with a higher cost, and its roles were gradually substituted by other solvents. With the development of the route of reaction between normal butenes and acetic acid, the production cost could be reduced dramatically. The applications, the synthesis processes, especially the process from the reaction between normal butenes and acetic acid, and the domestic market analysis, of secbutyl acetate were reviewed.
