Abstract
Processes for producing carboxylic acid are included herein. The processes include contacting methanol and carbon monoxide in the presence of a liquid reaction medium under carbonylation conditions sufficient to form a carbonylation product including acetic acid and one or more components selected from acetaldehyde, formic acid and combinations thereof, wherein the liquid reaction medium includes: a carbonylation catalyst selected from rhodium catalysts, iridium catalysts and palladium catalysts; and water in a water concentration in a range of 1 wt. % to 14 wt. % based on the total weight of the liquid reaction medium; and contacting at least a portion of the carbonylation product or a derivative thereof with an adsorbent at adsorption conditions sufficient to selectively reduce a concentration of one or more components present in the carbonylation product, wherein the adsorbent includes a silicoaluminophosphate (SAPO).
