Application

2-Propanol (Isopropanol) has been used for isolation and quantitative determination of carotenes and xanthophylls from Capsicum annum pericarp extracts by HPLC. It has been used as solvent in the dissolution of Pt and TiO2 precursors, for the fabrication of Pt-TiO2/Ti electrodes.

2-propanol may be used in the synthesis of methyl isobutyl ketone with satisfactory yield in the presence of bifunctional Cu-base catalysts. It can undergo oxidation in the presence of titanium oxide-supported manganese oxide to form acetone.

General description

2-Propanol (Isopropanol) is a secondary alcohol. It has been tested as substitute to fuel for various fuel cells. Cuo powder dissolved in 2-propanol has been used for the laser ablation assisted synthesis of Cu colloids. Its suspension with Zn(NO3)2 has been employed for the fabrication of titanium dioxide-coated stainless steel (P25-TiO2/SS) photoanode coated with uniformly thick layer of P25-TiO2. This photoanode was used for the electrochemical photocatalytic (ECPC) degradation process.
