1,4-Butanediol, also called Butane-1,4-diol (other names include 1,4-B, BD, BDO and 1,4-BD), [5] is a primary alcohol and an organic compound with the formula HOCH 2 CH 2 CH 2 CH 2 OH. . It is a colorless viscous liquid first synthesized in 1890 via acidic hydrolysis of N,N'-dinitro-1,4-butanediamine by Dutch chemist Pieter Johannes Dekkers, who called it "tetramethylene glyco
Isobutylene glycol may be considered a kind of butylene glycol, similarly to butane historically including n-butane and i-butane (isobutane). The modern name for the closely related type of compounds is methylpropanediol. There are two stable structural isomers: 2-methylpropane-1,2-diol; 2-methylpropane-1,3-diol; and one unstable geminal diol:
1,3-Butanediol is an organic compound with the formula CH 3 CH(OH)CH 2 CH 2 OH, not to be confused with 1,4 Butanediol. With two alcohol functional groups, the molecule is classified as a diol.
The (2R,3R)-stereoisomer of 2,3-butanediol is produced by a variety of microorganisms in a process known as butanediol fermentation. [4] It is found naturally in cocoa butter, in the roots of Ruta graveolens, sweet corn, and in rotten mussels.
This diol was first described by Charles-Adolphe Wurtz in 1859. [4]It is produced industrially by hydration of 1,2-epoxybutane. [5] [6]This process requires a ten- to twenty-fold excess of water to suppress the formation of polyethers.
Propane-2,2-diol, an example of a geminal diol. A geminal diol has two hydroxyl groups bonded to the same atom. These species arise by hydration of the carbonyl compounds. The hydration is usually unfavorable, but a notable exception is formaldehyde which, in water, exists in equilibrium with methanediol H 2 C(OH) 2
Bui is the last of the three friends to enter a plea in the fire that killed Djibril Diol, 29, and Adja Diol, 23, and their 22-month-old daughter, Khadija Diol. Their relative, Hassan Diol, 25 ...
2,3-butanediol fermentation produces smaller amounts of acid than mixed acid fermentation, and butanediol, ethanol, CO 2 and H 2 are the end products. While equal amounts of CO 2 and H 2 are created during mixed acid fermentation, butanediol fermentation produces more than twice the amount of CO 2 because the gases are not produced only by formate hydrogen lyase as they are in mixed acid ...
