Abstract:
A process for the production of a carbonyl compound, comprising the steps of:(a) reacting a carbonylatable compound with a carbon monoxide feed in a reactor in the presence of carbonylation catalyst including a noble metal complex supported on a porous, cross-linked vinylpyridine resin to obtain a liquid product containing the carbonyl compound; and(b) discharging said liquid product from said reactor and separating said carbonyl compound from said liquid product said discharged liquid product in a flasher and/or a distillation tower,wherein step (a) is performed at a temperature of 140-250.degree. C and at a carbon monoxide partial pressure of 7-30 kg/cm.sup.2 and a hydrogen partial pressure is maintained at 0.1-5 kg/cm.sup.2 while maintaining the water content and the carbonylation degree of the reaction solution within said reactor at 0.5-10% by weight and within the range of 0.5-0.9, respectively, andwherein the water content and the carbonylation degree of said discharged liquid product are maintained at not greater than 10% by weight and not greater than 0.9, respectively.
