1,4-Butenediol major uses: through riging-closing reaction can
form oxygen heterocyclic ring, mainly used to produce
pyridoxol (Vitamin B6) and intermediate of furan nudeus
pharmaceuticals. 1,4-Butenediol can be used to synthesis
intermediate pesticide endosulfan, which was widely used at
present. 1,4-Butenediol halogen ester can be used to produce
bactericide and anti-adherenet for papermaking. 1,4-Butenediol
can be used as additive for electroplating to achieve
bright-ductile planting layer. 1,4-Butenediol can be used to
produce polyester. E.g. after hydrolysising, the product
1,2,4-butanetriol(BT) can be polymerized into polybutylene
terephthalate(PBT) resin, which is a highstrength, heat
resistant and widely-used engineering plastic. 1,4-Butenediol
can also be polymerized into vinylester copolymer,
polyurethane, plasticizer and antifreezer.
