CO+H_2合成低碳醇是由煤制取液体燃料和化工原料的主要途径之一。随催化剂不同,可以合成以甲醇和异丁醇为主,用作汽油掺合剂的低碳燃料醇,也可得到以正构醇为主,用以生产化工原料用的醇类的低碳化学醇。这两种合成醇中异构体多,水份多,因此用填充柱分离,常有一定困难。1987年徐淑英用OV-101毛细管柱对 CO + H 2 synthesis of lower alcohols is one of the main ways to make liquid fuels and chemical raw materials from coal. With different catalysts, methanol and isobutanol can be synthesized mainly as a low-carbon fuel alcohol gasoline admixture, but also can be obtained mainly to n-alcohols, alcohols used in the production of chemical raw materials of low-carbon chemical alcohol . These two kinds of synthetic alcohol isomers and more water, so with a packed column separation, often a certain difficulty. In 1987 Xu Shuying with OV-101 capillary column pair
