1,4-Butanediol (BDO)
DESCRIPTION
1,4-butanediol (1,4-BD) is a colorless, viscous liquid derived from butane containing alcohol groups at each end of its molecule. It is one of four stable isomers of butanediol
PRODUCT GROUP
- Monomers, Building Blocks & Intermediates
SYNONYMS
BDO, Tetramethylene glycol
MAJOR APPLICATIONS
As a chemical intermediate, BDO can be used in the field of THF, PBT and PU. THF is the primary derivative of 1,4-butanediol, accounting for over half of consumption, with the majority of THF used for PTMEG production. Polybutylene terephthalate (PBT) resins used in the production of engineering plastics is the next-largest market, at about 22% of global consumption. In PU applications, 1,4-butanediol is widely used as a chain extender at room temperature in MDI and aliphatic diisocyanate systems.
