    • 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.
    • 一种通过使羰基化合物如甲醇与一氧化碳在羰基化催化剂存在下反应生产羰基化合物的方法,所述羰基化催化剂含有负载在多孔交联的乙烯基吡啶树脂上的贵金属配合物, 140-250℃,一氧化碳分压为7-30kg / cm2,氢分压为0.1-5kg / cm2,得到含有羰基化合物和未反应的含CO气体产物的液体产物。 反应器内的液体产物的水含量和羰基化度分别保持在0.5-10重量%和0.5-0.9。羰基化合物与闪蒸器和/或蒸馏塔中的液体产物分离,由 钛或钛 - 钯合金。 将液体产物引入减压阀中,然后在加入闪蒸器和/或蒸馏塔之前与含CO气体产物混合。
