METHOD OF REMOVAL OF C-C-ALKYLIODIDE COMPOUNDS FROM LIQUID CARBOXYLIC ACID CONTAINING 2-6 CARBON ATOMS, AND/OR FROM CORRESPONDING CARBOXYLIC ACID ANHYDRIDE Russian patent published in 1995 - IPC

FIELD: chemical technology. SUBSTANCE: purification of acetic acid from impurities of C₁-C₁₀-alkyliodide compounds is carried out by contacting liquids with macroporous cation-exchange resin on the basis of cross-linking polystyrene matrix functional groups of which were substituted with silver or mercury atoms by at least 1%. Resin has thiol-groups, in part, arylthiol-groups of the formula , or thiouronium groups of the formula (I) as functional groups. Preferable content of silver or mercury is 7-12% of resin mass; carboxylic acid is acetic acid, corresponding carboxylic acid anhydride is acetic anhydride. Method is used for acetic acid purification. EFFECT: improved method of purification. 6 cl, 2 dwg, 1 tbl
