1.4-Butanediol Description:

1.4-Butanediol (chemical formula: HOCH2CH2CH2CH2OH) is one of the isomers of butanediol, a terminal dihydroxy substituent of butane, which is a colorless, viscous liquid at room temperature. Industrially, BDO is produced by allowing acetylene to react with two molecules of formaldehyde to form BDO, which is then hydrogenated. BDO can also be obtained by gas-phase hydrogenation of anhydrides.


1.4-Butanediol Instruction:

1,4-Butanediol is used industrially as a solvent for the production of plastics and fibers. At high temperatures, BDO is cyclized out of water to form tetrahydrofuran (THF), at 200°C and catalyzed by a ruthenium catalyst.

BDO is dehydrogenated to form gamma-butyrolactone (GBL). Both substances are quite important as industrial solvents. In addition, BDO is necessary for the production of the engineering plastic polybutylene terephthalate (PBT).

1,4-Butanediol Applications:

1,4-Butanediol has a wide range of applications. In the United States and Western Europe, more than half of BDO is used for the production of tetrahydrofuran, followed by gamma-butyrolactone, the latter being a rapidly developing engineering plastic.

BDO is used as a chain extender and polyester raw material for the production of polyurethane elastomers, esters made from 1,4-butanediol are good plasticizers for cellulose, polyvinyl chloride, polyacrylates and polyesters.

1,4-Butanediol has good hygroscopic elasticity and is used as a gelatin softener, a treatment agent for cellophane. BDO can also prepare N-methylpyrrolidone, and can also be used in the preparation of vitamin B6.

Cross-linking agent, organic synthesis for manufacturing polyurethane with high elasticity. BDO can prepare pyrrolidone derivatives such as N-methylpyrrolidone, N-vinylpyrrolidone, etc. BDO is also used in the preparation of vitamin B6, pesticides and herbicides.
