Butanediol (BDO)

1,4-Butanediol colloquially known as BD or BDO is a slightly-toxic, non- hazardous, colorless liquid or solid (depending on the temperature) organic chemical compound. The viscous liquid is used in industry as a solvent, a coating-resin raw material, and in chemical and pharmaceutical production.

1,4-Butanediol (BDO) is a liquid organic compound with the molecular formula C4H10O2 and CAS 110-63-4. It is almost odorless, combustible, and is one of four stable isomers of butanediol.

BDO is readily soluble in water, alcohols, ketones, glycol ethers, and glycol ether acetates. It is less soluble in diethyl ether and esters. The liquid compound is not miscible with aliphatic and aromatic hydrocarbons and chlorinated hydrocarbons.

Although BDO can be slightly irritating to the skin, eyes, and respiratory tract, it is considered non-toxic and only slightly hazardous to health. Ingestion of large quantities would be needed to produce adverse symptoms.

BDO is used in industry to manufacture adhesives and sealant chemicals, Intermediates, solvents and in the production of some types of plastics, polyurethanes, and elastic fibers. 1,4-Butanediol is used for the synthesis of y-butyrolactone (GBL) in organic chemistry.

Although several methods of manufacturing BDO are used, the most prevalent method worldwide is the BASF Reppe process, which makes butanediol from acetylene and formaldehyde by high-pressure synthesis.

In 2013 worldwide production was approximately one million metric tons according to the US government statistical index. Nearly half of the production was dehydrated to tetrahydrofuran to make fibers such as Spandex.
