General description
2-Butanol is secondary alcohol mainly used as a solvent in organic synthesis. 2-butanol readily converts into 2-butanone (methyl ethyl ketone, MEK), which is used as a solvent in the industrial sector and many domestic cleaning products. It is an intermediate in devulcanizing rubber and the production of alkyl ester for use as biodiesel fuel.
Application
2-Butanol is used:
- As a precursor to produce 2-butanone in presence of KMnO4 oxidant and CPC (N-cetylpyridinium chloride) micellar catalyst.
- In the production of CH3NH3PbI3 perovskite films.

Tantalum compounds as heterogeneous catalysts for saccharide dehydration to 5-hydroxymethylfurfural.
Fengli Yang et al.
Chemical communications (Cambridge, England), 47(15), 4469-4471 (2011-03-04)
A new solid acid, based on tantalum hydroxide, was used to catalyze saccharide dehydration into 5-hydroxymethylfurfural (HMF) with high catalytic activity and excellent stability in a water-2-butanol biphasic system. Furthermore, good results were also obtained from Jerusalem artichoke juice with

Anesthesia and analgesia, 103(1), 86-91 (2006-06-23)
Chirality has been proposed as a means for distinguishing relevant from irrelevant molecular targets of action, but the sensitivity and specificity of this test is unknown for volatile anesthetics. We applied enantiomers of two chiral anesthetic alcohols (2-butanol and 2-pentanol)

The effect of temperature and concentration on the structure of sec-butyl alcohol and isobutyl alcohol/water binary mixtures in the alcohol-rich region (mole fraction of water X(H2O) < 0.3) has been studied using Fourier transform (FT) near-infrared (NIR) spectroscopy. The experimental
