Oximes from Oximes
« on: September 23, 2002, 03:39:00 AM »
US Patent 3124613 discusses reacting lower oximes such as acetoxime with ketones to form higher oximes. e.g. 36.5 gms acetoxime, 60 gms cyclohexanone and 1 ml HCl refluxed and the acetone is distilled off as it forms giving 41.5 gms of the cyclohexanone oxime. Some of the lower oximes are used as anti skinning agents in paints (eg methyl ethyl ketoxime) and are probably available.
