Popis

General description

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 CO₃^2- 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.

Application

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.

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 .
