Colorless mobile liquid.
Slightly soluble in water, miscible with alcohol, propylene glycol and oils.

This ketone, commercially available in volume, has found some use as part of masking odors for industrial purposes. Its low cost and diffusive odor, also partly its very poor tenacity make it a useful masking odor where the objectionable odor is of high volatility (solvents, fuels, acrylic odors, etc.).
1) by oxidation of Methyl-iso-propylicarbinol (2-Methyl-3-butanol). 2) from iso-Propyl magnesium bromide plus Acetaldehyde, followed by reaction as 1). 3) from 2-Methylbutene plus Hydriodic acid via Methyl-iso-propyl carbinyl iodide.
