ABSTRACT:
In a process for purifying a carboxylic acid fraction obtained by liquid phase carbonylation of an alkyl alcohol and/or its reactive derivative in which volatile iridium- and/or volatile co-promoter contaminants are converted to involatile forms by contacting with an iodide in the absence of carbon monoxide or at a partial pressure less than that of the carbonylation reaction. The involatile contaminants are then separated from the carboxylic acid.
