Descrição geral

Mixtures of TiO2 (P25) with rare earth oxides (La2O3 or Y2O3) calcined at 700°C or 650°C have been reported to efficiently photocatalyze oxidation of acetone. Its aldol condensation in vapor-phase has been investigated over MgO promoted with alkali (Li, Na, K and Cs) or alkaline earth (Ca, Sr and Ba) metal ions. It undergoes Aldol condensation 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. Enantioselective Aldol condensation of acetone with various isatins in the presence of dipeptides (catalyst) 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 was used in the synthesis of Ga (Gallium)-DOTATATE (where DOTA=1,4,7,10-tetraazacyclo- dodecane -1,4,7,10-tetraacetic acid) chemicals. It may be used in an assay for determination of ester groups in lipids by spectrophotometric methods.
