What is a Butanediol?

Butanediol is an organic compound with the chemical formula C₄H₈O₂, belonging to the class of diols with two hydroxyl groups (-OH). There are four isomers of butanediol: 1,2-butanediol, 1,3-butanediol, 2,3-butanediol, and 2,4-butanediol, each of which is used for different purposes. The most widely used isomer is 1,4-butanediol (1,4-BDO), which serves as an important intermediate in the chemical industry.

1,4-Butanediol is primarily used in the production of polyurethanes and polyesters. Polyurethanes are widely used in applications such as furniture, automotive seats, insulation materials, and clothing. In addition, 1,4-butanediol is used as a solvent in chemical reactions. It is also utilized in the pharmaceutical and cosmetic industries as a humectant and moisturizer.

Furthermore, 1,4-butanediol is used in the synthesis of chemical products like γ-butyrolactone (GBL) and tetrahydrofuran (THF), which are important raw materials for other chemical products. 1,3-butanediol (1,3-BDO) is used in the production of polybutylene terephthalate (PBT), which is used in electronics and automotive parts. Butanediol is typically produced from petrochemicals, but in recent years, methods of producing it from biomass have been developed, offering the potential for reducing environmental impact. Proper safety measures are required when handling butanediol.
