摘要： The present disclosure provides for a method for measuring the concentration of one or more components in the reactor or a separation unit of an acetic acid process by both infrared and Raman spectroscopic analyses. In some embodiments, the conditions in the reactor or in any subsequent step of the acetic acid production process are adjusted in response to the measured concentration of one or more components.

摘要： Processes for producing acetic acid and determining corrosion therein are described herein. The processes generally include contacting methanol and carbon monoxide in the presence of a liquid reaction medium under carbonylation conditions sufficient to form acetic acid, wherein the liquid reaction medium includes: a carbonylation catalyst selected from rhodium catalysts, iridium catalysts and palladium catalysts; from 1 wt. % to 14 wt. % water; and one or more, in-situ generated derivatives of the one or more additives and combinations thereof; wherein the one or more additives are independently selected from non-benzoyl containing pentavalent phosphine oxides, compound mixtures of at least four phosphine oxides and pentavalent aryl or alkaryl phosphine oxides including one or more benzoyl groups; and recovering acetic acid from the process.

摘要： Processes for producing acetic acid are presented herein. One or more embodiments include processes for controlling downstream water concentration in acetic acid production process including contacting methanol and carbon monoxide in the presence of a reaction medium under carbonylation conditions sufficient to form a carbonylation 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 concentration by determining a target water concentration and introducing the tertiary phosphine oxide to the reaction medium at a rate, basicity, concentration or combination thereof sufficient to provide a downstream water concentration within 1 wt. % of the target water concentration.
