| 摘 要： | 用净化黄磷尾气为原料与甲醇液相合成甲酸甲酯 ,并对影响一氧化碳及甲醇转化率、甲酸甲酯时空收率等的因素进行了研究。研究结果表明 ,随着主催化剂浓度或反应压力的增大 ,一氧化碳转化率及甲醇转化率均提高 ;助剂的加入可以大大提高甲酸甲酯时空收率和延长催化剂的寿命。优化的反应条件为 :主催化剂 (甲醇钠 )浓度 0 .4mol L ;助催化剂吡啶浓度 1.74mol L ;温度 80℃ ;时间 160min ;压力 4MPa。在此条件下 ,黄磷尾气中一氧化碳及甲醇转化率可分别达到 95 .5 %和 43%。

| Abstract: | The synthesis process of methyl formate (MF) from purifying yellow phosphorus tail gas and methanol, and some influence factors of synthesize MF, are studied in this paper. The experiment results show that add promoter-pyridine in the catalyst can accelerate the speed of reaction and increase yield of MF, and the optimum reactive condition is at temperature of 80?℃?CO pressure of 4.0?MPa?the MeONa concentration of 0.4?mol/L?pyridine concentration of 1.74 ?mol/L, theconversion of CO and methanol are 95.5% and 43% respectively. |
