Production Process and its Technical Progress of 1,4-Butanediol

1,4- Butanediol （BDO） is a fundamental raw material of organic chemical and fine chemical industry, and has a very wide range of use. This paper introduced application fields and the production processes of BDO. The main production processes of BDO included acetylene -formaldehyde process, maleic anhydride process, butadiene process, and propylene oxide process. The paper focused on acetylene - formaldehyde process and maleic anhydride process. The paper also analyzed and compared the characteristics of different production processes of BDO, and reviewed the new technical progress of BDO at home and abroad. According to the present situation of BDO industry in China, some suggestions on newbuilding BDO has been put forward.
