Method of purifying carboxylic acid |
| abstract |
FIELD: chemical industry. SUBSTANCE: described is method of purifying C 2 -C 11 carboxylic acid resulting from liquid phase C 1 -C 10 alkyl alcohol and/or reactive derivative thereof in said method volatile iridium and/or volatile copromoter impurities are converted into non-volatile forms when the latter are reacted with iodide in the presence of carbon monoxide at its partial pressure which is less than that during carbonylation reaction. Nonvolatile impurities are then separated from carboxylic acid. EFFECT: more efficient purification method. 10 cl, 2 dwg, 2 ex |
