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.1 Its anticonvulsant property has been studied. Acetone in combination with tetraalkylammonium chloride forms an efficient solvent system for dissolving cellulose. P84 (polyimide membrane)/TAEA (tripodal amine (tris(2-aminoethyl)amine) cross-linked asymmetric flat sheet membranes based pervaporation for the dehydration of acetone has been reported. A recent study reports the photolysis of acetone vapors 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.1

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

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