BDO(1,4-butanediol) is an important organic chemical raw material, which is widely used in polymers, solvents, plasticizers, pharmaceuticals, pesticides and other fields. In the field of chemical production raw materials, BDO upstream and downstream related products are very rich, the following will be described in detail BDO and its downstream upstream and downstream related products.

1. the upstream raw material of BDO

1. Acetylene: Acetylene is one of the main raw materials of BDO, and high-quality BDO products can be produced by the acetylene method.
2. Formaldehyde: Formaldehyde is also one of the raw materials for the production of BDO. Through the reaction of formaldehyde and acetylene, 1,4-butynediol can be generated, and then BDO can be obtained through hydrogenation reaction.

2. BDO downstream products

1. PBT (polybutylene terephthalate):BDO is one of the main raw materials for the production of PBT. PBT is a high-performance engineering plastic with excellent heat resistance, chemical resistance and electrical insulation. It is widely used in automobiles, electronic appliances, aerospace and other fields.
2. γ-butyrolactone (GBL):GBL is an important solvent and chemical intermediate, which can be used in the production of nitrogen fertilizer, pesticide, pharmaceutical intermediates and so on.
3. Tetrahydrofuran (THF):THF is a common solvent and chemical intermediate used in the production of polymers, pharmaceuticals, etc.
4. Polyurethane (PU):BDO can be used to produce polyurethane. Polyurethane is a polymer material with excellent elasticity, abrasion resistance, chemical resistance, etc., and is widely used in furniture, construction, automobiles and other fields.

3. the upstream and downstream associated products of BDO and its downstream products

1. PTA (terephthalic acid):PTA is another main raw material for the production of PBT, which reacts with BDO to produce PBT.
2. Ethylene glycol (EG): Ethylene glycol is one of the main raw materials for the production of polyurethane, which reacts with BDO to produce polyurethane.
3. Adipic acid (AA): Adipic acid is one of the main raw materials for the production of nylon 66, and nylon 66 together with PBT can produce high-performance engineering plastic alloys.

In summary, as an important organic chemical raw material, BDO has a wide range of upstream and downstream related products, involving polymers, solvents, plasticizers, pharmaceuticals, pesticides and other fields. With the continuous progress of science and technology and the continuous expansion of applications, the types and uses of BDO and its upstream and downstream related products will continue to increase.
