One or more embodiments include processes for controlling downstream water concentration in acetic acid production process including contacting methanol and carbon monoxide in the pres - ence of a reaction medium under carbonylation conditions sufficient to form a carbonvlation product including acetic acid, wherein the reaction medium includes a carbonylation catalyst, water in an upstream water concentration of from 1 wt.% to 14 wt.% water, and a tertiary phosphine oxide; recovering acetic acid from the carbonylation product: and controlling a downstream water concen­ tration by determining a target water concentration and introducing the tertiary phosphine oxide to the reaction medium at a rate, ba - sicity, concentration or combination thereof sufficient to provide a downstream water concentration within 1 wt.% of the target water concentration.
