Beschreibung

Allgemeine Beschreibung

Mixtures of TiO₂ (P25) with rare earth oxides (La₂O₃ or Y₂O₃) calcined at 700°C or 650°C 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 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.

Anwendung

Die Lumineszenz-Intensität von Aceton ist abhängig von den Komponenten in der Lösung. Die Absorption von UV-Licht durch Aceton führt zur Photolyse und der Bildung von Radikalen .

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.
