| 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. |
| 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. |
