General description

Acetone is a polar organic solvent. It can undergo photocatalytic oxidation in the presence of mixed TiO2-rare earth oxides.

Application

Acetone undergoes aldolization in the presence of Mg-Al layered double hydroxides (LDH) as catalysts and Cl- and/or CO32- as compensating anions to afford diacetone alcohol and mesityl oxide as the main products. Its enantioselective Aldol condensation with various isatins in the presence of a dipeptide catalyst forms 1-alkyl 3-(2-oxopropyl)-3-hydroxyindolin-2-ones. Aqueous solution of acetone may be used as a medium for the oxidation of alkynes to 1,2-diketones using potassium permanganate.
Acetone′s luminesence intensity is dependent upon the solution components . The absorption of UV light by acetone, results in its photolysis and the production of radials .
