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.

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

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

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)

A breath-based adherence system to document ingestion of oral medications (e.g., HAART) was investigated. Specifically, the food additive 2-butanol, which can be easily packaged with a drug, is converted via alcohol dehydrogenase to the volatile metabolite 2-butanone that rapidly appears

The enantioselective chemisorption of R- and S-propylene oxide has been measured either on clean Pd(111) that has been exposed to S-2-butanol at various temperatures to vary the proportion of 2-butanol and 2-butoxide species or by adsorbing S-2-butanol on oxygen-covered Pd(111)
