1,4-Butenediol (BDO) is an important organic chemical raw material, widely used in polymers, solvents, pharmaceuticals, pesticides and other fields. In the field of raw materials for chemical production, the upstream and downstream related products of 1,4-butenediol are very rich. The following are some major upstream and downstream products:

upstream products:

1. Acetylene: Acetylene is one of the main raw materials for the production of 1,4-butenediol, and BDO can be synthesized by acetylene method.

2. Formaldehyde: Formaldehyde is also an important raw material for the production of BDO. Through the reaction of formaldehyde and acetylene, 1,4-butynediol can be generated, and then BDO can be obtained by hydrogenation reaction.

downstream products:

1. Polybutylene terephthalate (PBT):BDO is one of the main raw materials for the production of PBT. PBT is a high-performance engineering plastic with excellent heat resistance, chemical resistance and electrical Insulation.

2. Tetrahydrofuran (THF):BDO can be converted to THF,THF is an important solvent and chemical intermediate, widely used in medicine, pesticides, resins and other fields.

3. Gamma-butyrolactone (GBL):BDO can also be converted to GBL, which is a high boiling point solvent used in the manufacture of synthetic fibers, pharmaceuticals and pesticides.

4. Polyurethane (PU):BDO can be used to produce PU. PU is a high-performance elastomer material widely used in furniture, construction, automobiles and other fields.

In short, as an important organic chemical raw material, 1,4-butenediol has a wide range of upstream and downstream related products, involving polymers, solvents, pharmaceuticals, pesticides and other fields.
