摘要

本文通过将KF浸渍在γ-Al2O3上制备了一系列碱性催化剂。以KF/Al2O3为催化剂，研究了甲醇、环氧丙烷(PO)和二氧化碳一锅法合成碳酸二甲酯(DMC)的工艺。结果表明，影响DMC收率和PO转化率的主要因素是催化剂的碱用量。较高的催化剂用量有利于提高反应活性。在所研究的催化剂中，17.5%KF/γ-Al2O3表现出较强的反应活性。

Synthesis of dimethyl carbonate from methanol, propylene oxide and carbon dioxide over KF/Al2O3

In this paper, a series of basic catalysts were prepared by impregnation of KF onto γ-Al₂O₃. The one-pot synthesis of dimethyl carbonate (DMC) from methanol, propylene oxide (PO) and carbon dioxide has been investigated using the KF/Al₂O₃ as catalysts. It was found that the main factors influencing the yield of DMC and the conversion of PO are the base amount of the catalysts. Higher amount of the catalyst is of beneficial for the improvement of reaction activity. Among the catalysts studied, 17.5%KF/γ-Al₂O₃ showed a competitive and superior reaction activity.
