2-METHYL-1-BUTANOL Usage And Synthesis

Definition

ChEBI: 2-methylbutan-1-ol is a primary alcohol that is isopentane substituted by a hydroxy group at position 1. It has a role as a Saccharomyces cerevisiae metabolite. It is an alkyl alcohol and a primary alcohol. It derives from a hydride of an isopentane.

Purification Methods

Reflux the butanol with CaO, distil, reflux with magnesium and again fractionally distil it. A small sample of highly purified material is obtained by fractional crystallisation after conversion into a suitable ester such as the trinitrophthalate or the 3-nitrophthalate. The latter is converted to the cinchonine salt in acetone and recrystallised from CHCl3 by adding pentane. The salt is saponified, extracted with ether, and fractionally distilled. [Terry et al.
