低温低压二步法合成甲醇

SYNTHESIS METHANOL UNDER LOW TEMPERATURE AND LOW PRESSURE BY TWO STEP PROCESS

二步法合成甲醇 ,其第一步是甲醇羰基化合成甲酸甲酯 ;第二步是甲酸甲酯氢解合成甲醇。二步反应的优点是使反应温度和压力降低、选择性提高、产物甲醇不含水 ,使提纯容易。从而低能耗。

Methanol have been obtained by means of two step reaction process.Carbonylation of methanol may produce methyl formate first and hydrogenalysis of methyl formate may obtain methanol second.The advantage of the process is that the reaction can carry out under low temperature and low pressure.The produced methanoldoes not contain water.Therefore the process of reaction can consume lower energy and can obtain higher yield for synthesis methanol.
