제목 Preparation of Dimethyl Carbonate from Transesterification of Ethylene Carbonate with Methanol using ImmobilizedQuaternary Ammonium Salt on MCM 41
초록 Quaternary ammonium salt supported on mesoporous silica catalysts (QCl-MS41) proved to be an effective heterogeneous catalyst for the synthesis of dimethyl carbonate (DMC) from ethylene carbonate (EC) with methanol by transesterification. The immobilized quaternary ammonium salt catalysts of longer alkyl chain length showed higher EC conversion and TON of DMC. High temperature and longer reaction time were favorable for the reactivity of QCl-MS41. However, carbon dioxide pressure showed a maximum in catalytic activity. The catalyst can be reused for the reaction up to three consecutive runs with only a slight decrease of its catalytic activity.
