Descrição geral

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.

Aplicação

A intensidade de luminescência da acetona depende dos componentes da solução . A absorção de luz UV pela acetona causa sua fotólise e produção de radiais .
Acetone may be employed in the following studies:
  • As 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.
