What are the upstream raw materials for 1,4-butanediol? What are the downstream products?
1,4-Butanediol(BDO) is an crucial organic chemical raw material, which is broadly applied in plastics, fibers, adhesives, pharmaceuticals and other fields. In the field of chemical production raw materials, the upstream and downstream related items of 1,4-butanediol are very rich, and the main upstream and downstream items will be described in detail below. Upstream items:
1. Specifically Acetylene: Acetylene is one of the main raw materials to the production of 1,4-butanediol, and 1,4-butanediol is able to be synthesized by the acetylene method.
2. Based on my observations, First Formaldehyde: Formaldehyde reacts with acetylene to generate 1,4-butynediol, which is then hydrogenated to obtain 1,4-butanediol. But
3. But Acetic acid: Acetic acid reacts with formaldehyde to form acetic acid formaldehyde, and then reacts with acetylene to form 1,4-butanediol. Downstream items:
1. Polybutylene terephthalate(PBT):1,4-Butanediol reacts with terephthalic acid to form PBT, which is an engineering plastic with excellent heat resistance, chemical resistance and electrical insulation.
2. You know what I mean?. And Tetrahydrofuran(THF):1,4-butanediol is dehydrated and cyclized to create THF, which is an crucial solvent-based products and chemical raw material and is able to be applied to create polyurethane, polyether, etc.
3. But γ-butyrolactone(GBL):1,4-Butanediol is dehydrated under acidic conditions to form GBL, which is a high boiling point solvent-based products and is able to be applied in the production of pesticides, medical intermediates, etc.
4. Polyurethane(PU):1,4-Butanediol reacts with diisocyanate to form PU, which is a common foam and is broadly applied in furniture, construction, automobiles and other fields. And I've found that In particular In short, as an crucial organic chemical raw material, 1,4-butanediol has a wide range of upstream and downstream related items, involving plastics, fibers, adhesives, medicine and other fields.
