Beschreibung

Allgemeine Beschreibung

Acetone is an organic solvent widely used in the polymer and pharmaceutical industry. It is found in mammalian tissues as a by-product of metalbolism. It shows potent anticonvulsant property. Acetone in combination with tetraalkylammonium chloride forms an efficient solvent system for dissolving cellulose. The dehydration of acetone can be accomplised by pervaporation using P84 (polyimide membrane)/TAEA (tripodal amine (tris(2-aminoethyl)amine) cross-linked asymmetric flat sheet membranes. The acetone vapors can undergo photolysis in a titanium dioxide (TiO₂) photocatalyst immobilized UV irradiated reactor.

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 may be employed in the following studies:

• 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.
• As a starting material to synthesize methyl methacrylate.

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

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