Abstract

e -Caprolactone is prepared by oxidizing cyclohexanone in the liquid phase by means of a gas containing molecular oxygen in the presence of benzaldehyde and an iron salt catalyst dissolved in the reaction mixture. The iron salt may be ferric benzoate produced by introducing into the reaction mixture an iron compound capable of reacting with benzoic acid therein to produce ferric benzoate, e.g. iron oxide. Other useful iron salts are ferric oleate, naphthenate and acetate. The temperature should be kept below 100 DEG C., preferably between 20 DEG and 50 DEG C. A solvent may be used, e.g. a hydrocarbon, chlorinated hydrocarbon or an ester. Benzoic acid and adipic acid are also produced in the process.ALSO:Polymerized caprolactone is prepared in a process for making e -caprolactone (see Division C2) which comprises oxidizing cyclohexanone in the liquid phase by means of a gas containing molecular oxygen, in the presence of benzaldehyde and an iron salt catalyst dissolved in the reaction mixture. The iron salt may be ferric benzoate produced by introducing into the reaction mixture an iron compound capable of reacting with benzoic acid, e.g. iron oxide. Other useful iron salts are ferric oleate, naphthenate and acetate. The temperature should be kept below 100 DEG C., preferably between 20 DEG and 50 DEG C.
