What is 1.4-Butanediol

1.4-Butanediol is an important raw material for the production of spandex, plastics, elastomers and films. BDO is used as a base material as well as a starting material for other SA derivatives such as THF and GBL. THF is produced from 1,4-DO in the presence of phosphoric acid under high temperature conditions. Figure 5 shows five known chemical processes for producing 1,4-PDO. Reppe chemistry was one of the first technologies to produce 1,4-butanediol from acetylene and formaldehyde.

1.4-Butanediol

图片
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.

Tetrahydrofuran (THF) is a colorless, volatile liquid with the odor of ether or acetone and is miscible with water and most organic solvents. THF is highly flammable and may thermally decompose into carbon monoxide and carbon dioxide.
