Abstract

1,172,655. Oxidation of cyclohexane. TOA GOSEI CHEMICAL INDUSTRY CO. Ltd. 6 March, 1968, No. 10894/68. Heading C2C. Cyclohexanol and cyclohexanone are obtained by continuously oxidizing cyclohexane in the liquid phase in a plurality of reactors connected in series with molecular O 2 or an O 2 -containing gas, under elevated pressure and at an elevated temperature in the presence of a transition metal catalyst, the O 2 consumed in the first reactor being in a range from about 0À010 to about 0À045 mols of O 2 /mol of cyclohexane supplied to the first reactor and supplying to at least the first reactor water in an amount defined by the following expression wherein X = the sum of the amount of O 2 consumed in first reactor/mol cyclohexane supplied to the first reactor and the amount of H 2 O carried by waste gas from the first reactor. The operating temperature may be from about 100‹ C. to about 180‹ C. and the pressure may be from about 5 to about 100 kg./cm.<SP>2</SP> An apparatus suitable for carrying out the process is described and the results of numerous runs are given.
