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.

Diastereomeric adducts between (S)-1-(4-fluorophenyl)-ethanol and R and S 2-butanol, formed by supersonic expansion, have been investigated by means of a combination of mass selected resonant two-photon ionization-spectroscopy and infrared depletion spectroscopy. Chiral recognition is evidenced by the specific spectroscopic signatures

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)
