(Redirected from Butylene glycol)

Butanediol, also called butylene glycol, may refer to any one of four stable structural isomers:

Geminal diolsEdit

There are also two geminal diols (gem-diols), which are less stable:

Isobutylene glycol and methylpropanediolEdit

Isobutylene glycol may be considered a kind of butylene glycol, similarly to butane historically including n-butane and 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:

  • 2-methylpropane-1,1-diol (not a glycol)

These three methylpropanediols are structural isomers of butanediols. They are not chiral.
