Beschreibung

Allgemeine Beschreibung

Acetone is a ketone. Mixtures of TiO₂ (P25) with rare earth oxides (La₂O₃ or Y₂O₃) calcined at 700°C or 650°C has been reported to efficiently photocatalyze the 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 was used in the affinity purification of modified proteins using streptavidin beads for the mass spectrometric (MS) identification of poly(ADP-ribose) polymerases (PARP) substrate proteins.
It may be used in the following studies:

• NMR spectroscopic evaluation of glucose metabolism in biological samples (blood).
• Preparation of 13wt% amorphous poly (lactic acid) (PLA) solution, which was required for the preparation of electrospun PLA membranes.
• As a precursor for the synthesis of methyl isobutyl ketone (MIBK) in the presence of sulfonated graphene oxide-Pd/cordierite catalyst.
• Synthesis of (4-hydroxymethyl-2,2-dimethyl-1,3-dioxolane), a solketal from glycerol using supercritical fluids (SCF) technology.

It may be used in the synthesis of the following acetone hydrazones:

• 1-isopropylidene-2-methylhydrazine
• 1-isopropylidene-2-hydroxyethylhydrazine
• 1-isopropylidene-2-formylhydrazine
