FIELD: industrial organic synthesis.
SUBSTANCE: method comprises contacting vapor-phase mixture at 150-205°C with alkali and/or alkali-earth metal carboxylate dispersed on activated carbon resulting in conversion of alkyl iodides into corresponding carboxylic acid esters, while iodine becomes bound in the form of inorganic iodide.
EFFECT: facilitated freeing of carboxylic acid product from organic iodine compounds.
