1,4-Butanediol, colloquially known as BD, is the organic compound with the formula HOCH2CH2CH2CH2OH. It is a colorless viscous liquid. It is one of four stable isomers of butanediol.
 

Synthesis

In its industrial synthesis, acetylene reacts with two equivalents of formaldehyde to form 1,4-butynediol. This type of acetylene-based process is illustrative of what is known as "Reppe chemistry", after German chemist Walter Reppe. Hydrogenation of 1,4-butynediol gives 1,4-butanediol. This route is used by BASF and Ashland/ISP. It is also manufactured on an industrial scale from maleic anhydride in the Davy process, which is first converted to the methyl maleate ester, then hydrogenated. Other routes are from butadiene, allyl acetate and succinic acid.

A biological route to BDO has been commercialized that uses a genetically modified organism.The biosynthesis proceeds via 4-hydroxybutyrate.

Industrial use

1,4-Butanediol is used industrially as a solvent and in the manufacture of some types of plastics, elastic fibers and polyurethanes. In organic chemistry, 1,4-butanediol is used for the synthesis of γ-butyrolactone (GBL). In the presence of phosphoric acid and high temperature, it dehydrates to the important solvent tetrahydrofuran. At about 200 °C in the presence of soluble ruthenium catalysts, the diol undergoes dehydrogenation to form butyrolactone.

World production of 1,4-butanediol was claimed to be about one million metric tons per year and market price is about 2,000 USD (1,600 EUR) per ton (2005). In 2013, worldwide production was claimed to be billions of lbs (consistent with approximately one million metric tons).

Almost half of it is dehydrated to tetrahydrofuran to make fibers such as Spandex. The largest producer is BASF.

Toxicity and use as a recreational drug

FDA warning against products containing GHB and its prodrugs, such as 1,4-butanediol.

1,4-Butanediol is also used as a recreational drug known by some users as "One Comma Four", "Liquid Fantasy", "One Four Bee" or "One Four B-D-O". It exerts effects similar to γ-hydroxybutyrate (GHB), which is a metabolic product of 1,4-butanediol. When mixed with other drugs, misuse of 1,4-butanediol has resulted in addiction and death.
