The processes include contacting an alcohol and carbon ----. monoxide in the presence of a liquid reaction medium under carbonylation conditions sufficient to form a carbonylation product in- cluding the carboxylic acid and recovering the carboxylic acid from the carbonylation product. The liquid reaction medium may in- c dude a carbonylation catalyst selected from rhodium catalysts, indium catalysts and palladium catalysts; water in a water concentra- ei tion ranging from 1 wt.% to 14 wt.% based on the total liquid reaction medium weight; and an additive, one or more in situ gener- 0 ated derivatives of the additive or combinations thereof, wherein the additive includes one or more salts of one or more compounds, each compound including at least one ammo group and at least one acid group, the at least one acid group capable of forming an al - 5- kali metal salt.
