ABSTRACT:
A process for the production of a carbonyl compound such as acetic acid by reacting a carbonylatable compound such as methanol with a carbon monoxide in the presence of a carbonylation catalyst containing a noble metal complex supported on a porous, cross-linked vinylpyridine resin at a temperature of 140-250.degree. C., a carbon monoxide partial pressure of 7-30 kg/cm.sup.2 and a hydrogen partial pressure of 0.1-5 kg/cm.sup.2 to obtain a liquid product containing the carbonyl compound and an unreacted CO-containing gas product. The water content and the carbonylation degree of the liquid product within the reactor are maintained at 0.5-10% by weight and 0.5-0.9, respectively, The carbonyl compound is separated from the liquid product in a flasher and/or a distillation tower formed of titanium or a titanium-palladium alloy. The liquid product is introduced into a pressure reducing valve and then mixed with the CO-containing gas product before being fed to the flasher and/or distillation tower.
