What is 14 butanediol?
Butane-1,4-diol, not to be confused with 1,3 butanediol, is a primary alcohol, and an organic compound, with the formula HOCH₂CH₂CH₂CH₂OH. It is a colorless viscous liquid. It is one of four stable isomers of butanediol.
What is 14 butanediol used for?
Butane-1,4-diol 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).
What are the side effects of butanediol?
It has been linked with very serious side effects, including trouble breathing, tremors, hallucinations, and death. Pregnancy and breast-feeding: 1,4-Butanediol is unsafe. Don’t use it. Slow heart rate (bradycardia): Gamma-hydroxybutyrate (GHB) is a chemical that is formed when the body breaks down 1,4-butanediol.
What is butanediol made from?
1,4-Butanediol (BDO) is produced by hydroformylation of allyl alcohol with carbon monoxide and hydrogen, which is then followed by hydrogenation. It is a colorless liquid with high boiling point and low toxicity.
Industrial use
Butane-1,4-diol 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. It is used to synthesize 1,4-Butanediol diglycidyl ether which is then used as a reactive diluent for epoxy resins.
World production of butane-1,4-diol was claimed to be about one million metric tons per year and market price is about US$ 2,000 (€ 1,600) 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
