摘要

A basic ionic liquid,namely choline hydroxide,was prepared and supported on MgO to form Choline hydroxide/MgO material.The supported ionic liquid material was characterized by XRD,FT-IR and TG and used as a catalyst in one-pot synthesis of dimethyl carbonate from propylene oxide,methanol and carbon dioxide.A good catalytic performance was obtained with 98% conversion of epoxide and selectivity of above 90% to DMC + PC over the composite catalyst.However,the catalyst could be reused three times without a significant change in its catalytic activity.
