Microporous H-ZSM-5 zeolite having good crystallinity and with the presence of Brønsted acid sites exclusively, was prepared by hydrothermal treatment of Expanded Perlite. The as-prepared H-ZSM-5 was used as heterogeneous catalyst for the reaction between vinyl acetate and isoamyl alcohol, as a greener alternative for the traditional preparation of isoamyl acetate. In this reaction, isoamyl acetate was generated by an acyl nucleophilic substitution mechanism, mediated by an acetylated zeolite complex, while acetaldehyde diisoamyl acetal has been produced as a secondary product due to a nucleophilic addition to acetaldehyde carbonyl carbon. The reaction was studied under different alcohol/ester molar ratio, supporting a second order kinetics when working under excess of one reactant. Moreover, an Eley-Rideal kinetic model has been suggested for a reaction mechanism of five steps, involving the ketalization of isoamyl alcohol and acetaldehyde as a parallel reaction that competes with transesterification.

通过对膨胀珍珠岩进行水热处理，可制得具有良好结晶度且仅存在布朗斯台德酸位的微孔H-ZSM-5沸石。所制备的H-ZSM-5用作乙酸乙烯酯与异戊醇之间反应的非均相催化剂，是传统制备乙酸异戊酯的绿色替代品。在该反应中，乙酸异戊酯是通过乙酰基沸石配合物介导的酰基亲核取代机理生成的，而乙醛二异戊基乙缩醛由于亲核加成到乙醛羰基碳上而作为副产物生成。在不同的醇/酯摩尔比下研究了该反应，当在一种以上的反应物下工作时，支持了二级动力学。而且，
