DESCRIPTION
General description
Mixtures of TiO2 (P25) with rare earth oxides (La2O3 or Y2O3) calcined at 700°C or 650°C efficiently causes oxidation of acetone.[1] 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.[2] 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.[3] Enantioselective Aldol condensation of acetone with various isatins in the presence of dipeptides (catalyst) has been described.[4]
Application
Acetone has been used in the preparation of 13wt% amorphous poly (lactic acid) (PLA) solution, which was required for the preparation of electrospun PLA membranes.[5] Acetone′s luminesence intensity is dependent upon the solution components. T
he absorption of UV light by acetone, results in its photolysis and the production of radials.
