    摘要: The phase separation in the decanter of a process for producing acetic acid by carbonylating methanol in the presence of a catalyst under low water-high acid conditions is improved by forming a liquid mixture (D) which has a water content of at most 20% by weight, based on the weight of the liquid mixture, and a weight ratio of acetic acid to water of at least 1:1, and partitioning the liquid mixture by providing for an alkane(s) content of D of from 0.1 to 15% by weight, based on the weight of D, to obtain a light, aqueous phase and a heavy, organic phase.

    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.
