Abstract
A process for preparing 6-chloro-2-hexanone which comprises the steps of (a) dehydrating cyclohexanol in the presence of a suitable catalyst and at a suitable temperature and for a sufficient period of time to form cyclohexene; (b) rearranging said cyclohexene at a higher temperature than in step (a) in the presence of a suitable catalyst and for a sufficient period of time to form 1-methylcyclopentene; (c) hydrating said 1-methylcyclopentene at a temperature lower than step (b) and in the presence of a resin catalyst for a sufficient period of time to form 1-methylcyclopentanol; (d) reacting said 1-methylcylcopentanol with a suitable amount of an alkali metal hypochlorite in the presence of a carboxylic acid to form 1-methylcyclopentyl hypochlorite; and (e) heating said 1-methylcyclopentyl hypochlorite for a sufficient period of time to form 6-chloro-2-hexanone.
