1,4-Butanediol (BDO) is produced by hydroformylation of allyl alcohol with carbon monoxide and hydrogen, which is then followed by hydrogenation. It is a colorless liquid with high boiling point and low toxicity.


Pharmaceutical intermediates, polytetramethylene ether glycol, solvent, adhesive.

Polytetramethylene ether glycol

Polytetramethylene ether glycol (PTMEG) is raw material for spandex fiber and polyurethane elastomer/thermoplastics/leather.

Polyester plasticizer

The polyester plasticizer based on 1,4-butanediol has excellent compatibility with the vinyl polymers.

Thermoplastic polyester

1,4-Butanediol can be used to manufacture polybutylene terephthalate (PBT), a high strength engineering plastic.


N-methyl pyrrolidone made from γ-Butyrolactone is a high-grade amide aprotic solvent that is used in petrochemical and other fields.
