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.
