Abstract: 1493231 2-(1-Cycohexenyl)-cyclohexanone STAMICARBON BV 12 Jan 1976 [17 Jan 1975] 01032/76 Heading C2C The invention comprises a process for preparing 2-(1-cyclohexenyl)-cyclohexanone by condensation of cyclohexamene, comprising effecting the condensation in the presence of a macro-porous ion exchanger as hereinafter defined at substantially atmospheric pressure and a temperature below 125C. wherein the conversion of the cyclohexanone is not allowed to rise above 50% and subjecting the reaction mixture obtained to distillation in the absence of the ion exchanger to remove 2-(1-cyclohexenyl)-cyclohexanone. The term "macroporous ion exchanger" is hereby defined as an ion exchanger which consists of sulphonated copolymer of styrene with from 15 to 20% by weight of divinyl benzene having pores whose average size exceeds 100 in diameter and/or with an internal surface area larger than 30 m 2 per gram.
