It was described for the first time by Charles Adolphe Wurtz in 1859 [ 5 ] . The carbon 2 atom with an alcohol function is chiral. Butane-1,2-Diol therefore exists in the form of two enantiomers.        (adsbygoogle = window.adsbygoogle || []).push({});after-content-x4  Butane-1,2-Diol is a viscous, colorless and unfinished liquid (flash point between 55 and 100 \u00b0C ). Its vapors can form explosive mixtures with the air when it is heated beyond its flash point. It is soluble to water, and slightly volatile. Butane-1,2-Diol is produced industrially as a by-product of the production of butane-1,4-diol from the Butadiene [ 6 ] And is also a by-product of the catalytic vapoccage of starchs and sugars, such as sorbitol, in ethylene glycol and propylene glycol [ 7 ] (However, the catalytic vapoccling of starchs and sugars is not currently one of the main synthesis processes of glycol ethylene and propylene glycol, partly because of the complexity of mixtures of polyhydritic alcohols formed). It is used to produce polyester resins and plasticizers [ 8 ] , [ 6 ] And can be a potential source for industrial production of \u03b1-cetoButyrique acid, a pioneer of many amino acids [ 9 ] .
