Abstract

Alkene epoxidation with TBHP as an oxidising reagent using heterogeneous Mo(VI) catalyst is an environmentally friendly process since it eliminates acid waste and chlorinated by-products often associated with the conventional industrial method that uses stoichiometric peracid such as peracetic acid and m-chloroperbenzoic acid. Polybenzimidazole supported Mo(VI) complex, i.e., PBI.Mo has been successfully prepared, characterised and assessed for the epoxidation of 1,5-hexadiene in the presence of tert-butyl hydroperoxide (TBHP) as an oxidising reagent. A quadratic polynomial model has been developed, demonstrating the yield of 1,2-epoxy-5-hexene in four independent variables. The effects of different parameters such as reaction temperature, feed mole ratio of 1,5-hexadiene to TBHP, catalyst loading, and reaction time were studied. Response surface methodology (RSM) using Box-Behnken Design (BBD) was employed to study the interaction effect of different variables on the reaction response. This study presents the optimization of 1,5-hexadiene epoxidation in a batch reactor using TBHP as an oxidant and a polymer-supported Mo(VI) catalyst.
在多苯并咪唑负载的Mo(VI)催化剂存在下,以过氧化叔丁基(thbhp)为氧化试剂更环保高效地环氧化1,5-己二烯
使用多相Mo(VI)催化剂,以三必和三必达为氧化试剂进行烯烃环氧化,是一种环保工艺,因为它消除了酸性废物和氯化副产物,这些副产品通常与使用过氧乙酸和间氯过氧苯甲酸等化学计量过氧酸的传统工业方法有关。多苯并咪唑负载Mo(VI)配合物,即PBI。Mo已成功制备,表征和评估了1,5-己二烯的环氧化存在的叔丁基过氧化氢(TBHP)作为氧化试剂。建立了一个二次多项式模型,在四个自变量下证明了1,2-环氧-5-己烯的产率。考察了反应温度、1,5-己二烯与三必和二醇的摩尔比、催化剂负载和反应时间等参数对反应的影响。采用Box-Behnken设计(BBD)的响应面法(RSM)研究了不同变量对反应响应的交互作用。本研究提出了在间歇式反应器中以三必拓为氧化剂和聚合物负载Mo(VI)催化剂优化1,5-己二烯环氧化反应。
