What are the upstream raw materials of BDO and what are the downstream products?

BDO(1,4-butanediol) is an crucial organic chemical raw material, which is broadly applied in plastics, fiber, rubber, medicine and other fields. In the field of raw materials to chemical production, there are many upstream and downstream related items of BDO, and some of the main upstream and downstream items will be described in detail below. You know what I mean?. Upstream items:



1. Acetylene: Acetylene is one of the crucial raw materials to BDO production, and BDO is able to be produced through acetylene method and acetylene aldehyde method. But

2. And Formaldehyde: Formaldehyde is also one of the crucial raw materials to BDO production. Formaldehyde and acetylene are applied to react to generate 1,4-butynediol, and then BDO is generated through hydrogenation interaction.

3. Acetic acid: Acetic acid is also applied as a raw material in some BDO production processes. Downstream items:



1. PBT(polybutylene terephthalate):BDO is one of the crucial raw materials to PBT production. PBT is a high-performance engineering plastic with excellent heat resistance, chemical resistance and electrical insulation. In fact it's broadly applied in automobiles, electronics, aerospace and other fields. And

2. Based on my observations, γ-butyrolactone(GBL):GBL is an crucial solvent-based products and chemical intermediate, is able to be applied to create N-methyl pyrrolidone(NMP), vinyl pyrrolidone(NVP) and other compounds, broadly applied in lithium batteries, medicine, pesticides and other fields. Tetrahydrofuran(THF):THF is an crucial organic solvent-based products and chemical intermediates, is able to be applied to create PTMEG(polytetramethylene ether glycol), polyurethane and other compounds, broadly applied in resins, coatings, pharmaceuticals and other fields.

4. Degradable plastics: BDO is able to be applied to create degradable plastics, such as PBS(polybutylene succinate), PBAT(polybutylene adipate/terephthalate), etc. In my experience, These degradable plastics have excellent biodegradability and ecological preservation, and are broadly applied in packaging, agricultural film and other fields. In short, as an crucial organic chemical raw material, BDO has a wide range of upstream and downstream related items, involving many fields, such as plastics, fibers, rubber, medicine, degradable materials, etc.
