  • Process for the production of acetic acid
    Patent number: 5672743
    Abstract: A process for the production of acetic acid by carbonylation of methanol or a reactive derivative thereof by contacting the methanol or derivative with carbon monoxide in a liquid reaction composition comprising (a) acetic acid, (b) an iridium catalyst, (c) methyl iodide, (d) at least a finite quantity of water and (e) methyl acetate is improved by the use as promoter of at least one of ruthenium and osmium.

  • Process for purifying a carboxylic acid
    Patent number: 5663430
    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.
