摘　　要：三羟甲基丙烷(TMP)的工业化生产方法有两种:康尼扎罗法和加氢法。基本原料都是正丁醛和甲醛。加氢法生产条件比较苛刻,但可节省1/3的甲醛,且副产物少、成本低、无三废、提取工艺简单。康尼扎罗法只适用于小批量间歇生产。国外BASF等公司已实现了加氢法TMP的工业化生产,而我国还是采用康尼扎罗法。2001年,全球TMP的产能已超过16万t/a。我国目前TMP的生产能力约为6000t/a,尚不能满足国内需求。There are two commercial methods of trimethylolpropane ( TMP ) production: Can- nizzaro method and hydrogenation method. Raw ma- terials are n-butyl aldehyde and formaldehyde. Al- though the condition of hydrogenation method is more rigorous, one third of formaldehyde can be saved, and it is characterized by less by-product, low cost, no 'three wastes' and simple extraction process. Cannizzaro method is suitable only for batch produc- tion in small scale. BASF and other foreign compa- nies have already realized commercial production of TMP by hydrogenation method, however, China still adopts Cannizzaro method. In 2001, the world ca- pacity of TMP was more than 0. 16 million tons. At present, China's capacity of TMP is approximately 6000t/a, which can not meet market demand.
