The Uses of 1,4-Butanediol

1,4-Butanediol is a basic chemical and fine chemical raw material, widely used in the production of PBT engineering plastics and fibers, and in the synthesis of tetrahydrofuran (THF) and polytetramethylene ether glycol (PTMEG, obtained by polymerization of THF) , polyether-type high-performance elastomers and spandex elastic fibers (synthesized from PTMEG and diisocyanate), unsaturated polyester resins, polyester polyols, butanediol ether solvents, and pharmaceutical and cosmetic industries. 1,4-butanediol can also be used to produce N-methylpyrrolidone, adipic acid, acetal, maleic anhydride, 1,3-butadiene, etc.


Y-butyrolactone, a downstream product of 1,4-butanediol, is the raw material for the production of 2-pyrrolidone and N-methylpyrrolidone, from which a series of high value-added products such as vinylpyrrolidone and polyvinylpyrrolidone are derived. Widely used in pesticides, medicine and cosmetics and other fields.

In the field of polyurethane, except for the synthesis of polytetrahydrofuran polyol, it is mainly used for the synthesis of polyester diol and as a chain extender for elastomers and microporous polyurethane shoe materials. Polybutylene adipate-based polyurethane has good crystallization sex.
