General description

Photocatalytic activity of mixtures of TiO2 (P25) with rare earth oxides for the oxidation of acetone has been reported. The vapor-phase aldol condensation of acetone over MgO promoted with alkali (Li, Na, K and Cs) or alkaline earth (Ca, Sr and Ba) metal ions has been studied. Acetone undergoes Aldol condensation in the presence of catalysts Mg-Al layered double hydroxides (LDH) and Cl- and/or CO32- as compensating anions to afford diacetone alcohol and mesityl oxide. Enantioselective Aldol condensation of acetone with several isatins has been described.

Application

Acetone is the suitable reagent for use in UV spectroscopy. It may be employed in the following studies:
  • As an organic solvent to investigate the zeta potential of TiO2 and Al2O3 powders.
  • Synthesis of poly(ortho esters) (POE), biodegradable carriers for drug delivery devices.
  • Spectrophotometric determination of ester groups in lipids.
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 .
