摘要：
Hydroxyaromatic compounds such as phenol are carbonylated with oxygen and carbon monoxide in the presence of a catalyst system comprising a Group VIIIB metal, preferably palladium; an alkali metal or alkaline earth metal halide, preferably sodium bromide; and a promoter compound which is at least one C2-8 aliphatic or C7-10 aromatic mono- or dinitrile, preferably acetonitrile or adiponitrile. The catalyst system also preferably contains a compound of a non-Group VIIIB metal, preferably lead.
