摘要：

Dimethyl carbonate was synthesized via transesterification of propylene carbonate by methanol using KF/Al2O3 as base catalyst. The catalyst was characterized using FT-IR, XRD, surface area measurement, alkalinity measurement and SEM analysis. The effect of KF loading on Al2O3, reaction parameters such as reaction temperature, reactant ratio and amount of catalyst on the product yield were investigated. It was found that the catalyst with 20 wt% KF loading on neutral alumina showed 70.9% propylene carbonate conversion with > 98% DMC selectivity.
