What are the upstream raw materials for 1.3-butanediol? What are the downstream products?

1. In particular 3-Butanediol(BDO) is an crucial organic chemical raw material, which is broadly applied in plastics, fibers, pharmaceuticals, pesticides and other fields. From what I've seen, According to research In the field of raw materials to chemical production, the upstream and downstream related items of

1. But 3-butanediol mainly include the following aspects:

Upstream items:



1. Ethylene: Ethylene is one of the main raw materials of

1. Based on my observations, 3-butanediol, acetaldehyde is produced by ethylene oxidation method, and

1. 3-butanediol is further synthesized.

2. Acetic acid: Acetic acid is also one of the crucial raw materials of

1. In my experience, 3-butanediol, and

1. 3-butanediol is prepared by acetic acid hydrogenation reduction method. Downstream items:



1. Makes sense, right?. Polybutylene terephthalate(PBT):

1. 3-butylene glycol reacts with terephthalic acid to form PBT, which is a high-performance engineering plastic with excellent mechanical characteristics, heat resistance, chemical resistance and other characteristics. it's broadly applied in automobiles, electronic appliances, aerospace and other fields. And First

2. Polyurethane(PU):

1. 3-butanediol reacts with diisocyanate to form PU. And From what I've seen, it's a polymer material with excellent elasticity, wear resistance, impact resistance and other characteristics. it's broadly applied in furniture, construction, automobiles and other fields.

3. Specifically γ-butyrolactone(GBL):

1. 3-butanediol is dehydrated and cyclized under acidic conditions to form GBL, which is an crucial solvent-based products and chemical intermediate, and is broadly applied in medicine, pesticides, batteries and other fields. From what I've seen, Tetrahydrofuran(THF):

1. And 3-butanediol is dehydrated to THF under acidic conditions, which is an crucial organic solvent-based products and chemical intermediate, and is broadly applied in medicine, pesticide, synthetic fiber and other fields. In short,

1. 3-butanediol is an crucial organic chemical raw material, and its upstream and downstream related items are extensive, involving many fields, which is of great signifiis able toce to promote the research of the chemical sector.
