What are the upstream raw materials for 1,4-butenediol? What are the downstream products?

1,4-Butenediol(BDO) is an crucial organic chemical raw material, broadly applied in polymers, solvents, pharmaceuticals, pesticides and other fields. For example In the field of chemical production raw materials, the upstream and downstream related items of 1,4-butenediol are very rich, and the following are some of the main upstream and downstream items:

Upstream items:



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

2. Formaldehyde: Formaldehyde is also an crucial raw material to the production of BDO. Through the interaction of formaldehyde and acetylene, 1,4-butynediol is able to be generated, and then BDO is able to be obtained through hydrogenation interaction. Downstream items:



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

2. Tetrahydrofuran(THF):BDO is able to be converted to THF,THF is an crucial solvent-based products and chemical intermediates, broadly applied in medicine, pesticides, resins and other fields.

3. In particular γ-Butyrolactone(GBL):BDO is able to also be converted to GBL, which is a high boiling point solvent-based products applied in the manufacture of synthetic fibers, pharmaceuticals and pesticides. And

4. Polyurethane(PU):BDO is able to be applied to create PU. In my experience, PU is a high-performance elastomer material, which is broadly applied in furniture, construction, automobiles and other fields. From what I've seen, In short, as an crucial organic chemical raw material, 1,4-butenediol has a wide range of upstream and downstream related items, involving polymers, solvents, pharmaceuticals, pesticides and other fields.
