摘要： Methods and systems for producing acetic acid, including glacial acetic acid. A first stream of a reactor fluid that includes methyl acetate, water, and a first amount of carbon monoxide may be forwarded from a reactor to a reactor cooler to form a cooled reactor fluid. The cooled reactor fluid may have a concentration of methyl acetate that is lower than the concentration of methyl acetate in the reactor fluid.

摘要： Reactor liquids, compositions, and methods of forming acetic acid, which may reduce catalyst loss. The reactor liquids and compositions may include, and the methods may use, a tri-aliphatic hydrocarbyl phosphine oxide. The carbonylation catalyst used in the methods may include rhodium. A composition comprising: acetic acid; water; and at least one tri-aliphatic hydrocarbyl phosphine oxide; wherein the acetic acid is present in the composition at an amount of about 60% to about 80%, by weight, based on the weight of the composition; wherein the water is present in the composition at an amount of about 0.1% to about 6%, by weight, based on the weight of the composition; and wherein the at least one tri-aliphatic hydrocarbyl phosphine oxide is present in the composition at an amount of about 2% to about 20%, by weight, based on the weight of the composition.
