摘要: Disclosed is a continuous process wherein carbon monoxide, a carbonylatable reactant, and a halide in the gas phase are contacted with a non-volatile catalyst solution comprising an ionic liquid and a Group VIII metal to produce a carbonylation product in the gas phase. The process is useful for the continuous preparation of acetic acid by the carbonylation of methanol.
