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 (PTMEG) is raw material for spandex fiber and polyurethane elastomer/thermoplastics/leather.
The polyester plasticizer based on 1,4-butanediol has excellent compatibility with the vinyl polymers.
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.
