In organic chemistry, 1.4-butanediol is used in the synthesis of gamma-butyrolactone (GBL). In the presence of phosphoric acid and high temperatures, 1.4-Butanediol dehydrates into the important solvent tetrahydrofuran. At about 200°C, in the presence of a soluble ruthenium catalyst, the diol undergoes a dehydrogenation reaction to form butyrolactone. BDO is used to synthesize 1,4-butanediol diglycidyl ether, which is then used as an epoxy resin diluent.

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.

Poly butylene adipate-co-terephthalate (PBAT) is a well-known aliphatic-aromatic biodegradable random copolyester. PBAT can be synthesized by polycondensation reactions in the melt phase. However, the synthesis process is very complex as PBAT requires high esterification temperatures, as well as vacuum to achieve molecular weights suitable for different grades.
