General description
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.
Application
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-isopropylidene-2-methylhydrazine
- 1-isopropylidene-2-hydroxyethylhydrazine
- 1-isopropylidene-2-formylhydrazine

Acetone containing tetraalkylammonium chloride is found to be an efficient solvent for cellulose. The addition of an amount of 10 mol% (based on acetone) of well-soluble salt triethyloctylammonium chloride (Et3 OctN Cl) adjusts the solvent's properties (increases the polarity) to
