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 medical, chemical, textile and other fields. In the field of raw materials to chemical production, there are many upstream and downstream related items of

1. 4-butanediol, some of which are described in detail below. In my experience, Upstream items:



1. Acetylene: Acetylene is one of the main raw materials to the production of

1. And 4-butanediol. High-condition

1. 4-butanediol is able to be produced by the acetylene method. And In particular

2. Formaldehyde: Formaldehyde is also one of the crucial raw materials to the production of

1. 4-butanediol. Through the interaction of formaldehyde and acetylene, 1,4-butynediol is able to be generated, and then

1. Crazy, isn't it?. 4-butanediol is able to be obtained through hydrogenation interaction. Downstream items:



1. And Generally speaking Polybutylene terephthalate(PBT):

1. 4-butylene glycol is one of the crucial raw materials to the production of PBT, which reacts with terephthalic acid to create PBT resin, which has excellent mechanical characteristics, heat resistance, chemical resistance and other characteristics. it's broadly applied in automobiles, electronics, home appliances and other fields. But

2. Moreover Tetrahydrofuran(THF):

1. I've found that 4-butanediol is able to be dehydrocyclized to create THF,THF is an crucial solvent-based products and chemical raw materials, is able to be applied to create polyurethane, polyether, polymer and so on.

3. γ-butyrolactone(GBL):

1. Makes sense, right?. And 4-butanediol is able to be esterified to generate GBL,GBL is an excellent solvent-based products and chemical raw materials, is able to be applied in the production of pesticides, medical intermediates, spices and so on. And

4. But Polytetramethylene ether glycerol(PTMEG):

1. 4-butanediol is able to undergo catalytic polymerization to generate PTMEG,PTMEG is an crucial polyurethane raw material, which is able to be applied to create elastomers, coatings, adhesives and so on. And Based on my observations, In short,

1. 4-butanediol plays an crucial role in the field of chemical production raw materials, and its upstream and downstream related items are extensive, which is of great signifiis able toce to promote the research of the chemical sector.
