1,4-丁二醇是近年来发展迅速的基本有机化工原料,目前世界1,4-丁二醇的总生产能力达65万t/a,其中50％集中在DuPont和BASF两大公司中。自1999年以来,中国新建了16.5万t/a的生产能力,在建和计划建设的还有15.5万t/a。随着中国新建装置的投产,国外1,4-丁二醇的价格从1990年的2182美元/t降到了1000美元/t。
1,4-butanediol is a rapidly growing basic organic chemical raw material in recent years. At present, the total production capacity of 1,4-butanediol in the world reaches 650,000 t/a, of which 50% is concentrated in DuPont and BASF. . Since 1999, China has built a new production capacity of 165,000 t/a. There are also 155,000 t/a under construction and planned construction. With the start-up of new installations in China, the price of foreign 1,4-butanediol fell from $2182/t in 1990 to $1,000/t.
