Purify the ketone by fractionation using an efficient column. It can be converted into the oxime which is distilled, b 117-118o/2mm, 145-146o/15mm, d 25 1.036, n D 1.5363; decompose the oxime, and the ketone is redistilled. It can also be purified via the semicarbazone which has m 154-155o. [Meyers et al. J Am Chem Soc 77 5655 1955, Hass et al. J Org Chem 15 8 1950, Beilstein 7 IV 712.]
