摘要
研究了二甲基甲酰胺 (DMF)助催化一氧化碳 (CO)、甲醇羰基化合成甲酸甲酯 (MF)的作用以及对催化剂活性的影响 .研究表明 :在一定反应压力下 ,助剂DMF能有效提高甲醇钠的催化活性 5 0 %以上 ,并可延长主催化剂甲醇钠的使用寿命 .还对DMF的助催化反应的工艺条件和机理进行了探讨 。
The functions of Dimethylformamide (DMF) in preparing Methyl formate (MF) from methanol and Carbon monoxide (CO) in the presence of an alkali metal methoxide, Sodium methoxide as catalyst and DMF as promoter are studied. The experimental results show that DMF can enhance the activity of Sodium methoxide by 50% and extend the life of catalyst to prepare MF at 3.8~4.3 MPa of system pressure in batch reactor. The technology condition of preparing MF is listed and the promoting reaction mechanism of DMF is discussed.
