Butylene oxide is an important organic chemical raw material, which is widely used in many fields. In the field of raw materials for chemical production, the upstream and downstream related products of butylene oxide mainly include the following aspects:

1. Upstream product

(1) Butene: Butene oxide is mainly produced from butylene as raw material and is produced by epoxidation reaction. Therefore, the price and supply of butene have a great influence on the production of butylene oxide.

(2) Hydrogen peroxide: Hydrogen peroxide is an oxidizing agent in the production of butylene oxide, which reacts with butylene to form butylene oxide.

2. Downstream products

(1) ethylene glycol: butylene oxide can be hydrolyzed to produce ethylene glycol, ethylene glycol is an important organic chemical raw material, widely used in the production of polyester fiber, unsaturated polyester resin, antifreeze and other fields.

(2)1,4-Butanediol: Butanediol can also undergo catalytic hydrogenation to generate 1,4-butanediol, which is an important fine chemical raw material and can be used to produce tetrahydrofuran, γ-butyrolactone, polybutylene terephthalate, etc.

(3) Glyoxal: Butylene oxide can also react with formaldehyde to form glyoxal. Glyoxal is an important organic synthesis intermediate that can be used to produce drugs, perfumes, dyes, etc.

To sum up, the upstream and downstream related products of epoxy butane are more extensive, involving many fields, such as polyester fiber, unsaturated polyester resin, antifreeze, medicine, perfume, dye and so on. Therefore, butylene oxide has an important position and role in the field of chemical production raw materials.
