Application

2-Propanol (Isopropanol) may be used in the following processes:Isolation and quantitative determination of carotenes and xanthophylls from Capsicum annum pericarp extracts by HPLC. As solvent in the dissolution of Pt and TiO₂ precursors, for the fabrication of Pt-TiO₂/Ti electrodes.As a solvent in the synthesis of di- and trisubstituted ortho biaryls by Suzuki-Miyaura cross-coupling reaction.As an alternate solvent to benzene in the analysis of total carbonyl compounds in heated and frying oils.As a reaction medium in the preparation of cyclic ureas by reacting CO₂ with diamines in the presence of pure cerium oxide (CeO₂).

Suitable for HPLC, spectrophotometry, environmental testing

General description

2-Propanol (Isopropanol) is a secondary alcohol. It has been tested as a substitute of the fuel for use in various fuel cells. CuO powder dissolved in 2-propanol has been used for the laser ablation assisted synthesis of Cu colloids. Suspension of 2-propanol 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. Preparation of methyl isobutyl ketone (MIBK) using 2-propanol as the precursor has been reported with yield as high as 25%. Solubility of benzoic acid has been investigated in 2-propanol by gravimetric method in the temperature range, 277-346K.
