Produced by treatment of Pinacone (Methyl-tertiary-butylketone) with Methyl iodide and Sodium amide. The process yields a number of homologues of subject material, and the Ethyl-tertiary-butyl ketone is the lowest boiling of these. The ketone can also be produced from Pentamethyl ethylene glycol by dehydration and rearrangement.
