以1GH_z、50mW—cm~(-2)微波连续辐照常压回流条件下直接酯化制备安息香酸酯反应体系。与常规回流方式相比,微波作用下反应温度虽然未变但反应速度提高10倍以上。本文探讨微波催化作用机制与分子间氢键及分子缔合性有关。
The benzoic acid ester reaction system was prepared by direct esterification with 1GH_z, 50mW-cm ~ (-2) microwave irradiation under atmospheric pressure. Compared with the conventional reflux method, although the reaction temperature is unchanged under microwave irradiation, the reaction rate is improved by more than 10 times. This article explores the mechanism of microwave catalysis and molecular hydrogen bonding and molecular associativity.
