Sigma Aldrich Fine Chemicals Biosciences Acetone suitable for HPLC1L
Supplier: Sigma Aldrich Fine Chemicals Biosciences 348501L
Mixtures of TiO2 (P25) with rare earth oxides (La2O3 or Y2O3) calcined at 700C or 650C efficiently causes 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.
