  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.

  本文描述了生产醋酸和测定其中腐蚀性的工艺。这些工艺一般包括在足以形成乙酸的羰基化条件下，使甲醇和一氧化碳在液体反应介质存在下接触，其中液体反应介质包括：选自铑催化剂、铱催化剂和钯催化剂的羰基化催化剂；1 wt.其中一种或多种添加剂独立选自不含苯甲酰基的五价膦氧化物、至少四种膦氧化物的化合物混合物和包括一个或多个苯甲酰基的五价芳基或烷基芳基膦氧化物；以及从该工艺中回收乙酸。
