用于制备乙酸的方法
摘要：
用于制备乙酸的方法，包括：将甲醇和/或其反应性衍生物和一氧化碳引入包含包括羰基化催化剂的第一反应区域中；将至少一部分该液态反应组合物与溶解的和/或夹带的一氧化碳和其他气体从该第一反应区域中取出；将至少一部分该取出的液态反应组合物送入第二反应区域，其中消耗掉该溶解和/或夹带的一氧化碳的至少一部分；将至少一部分该液态反应组合物从该第二反应区域送入闪蒸分离区域，其中从该第一反应区域中取出的该液态反应组合物的温度在170～195℃的范围；从该第二反应区域送入该闪蒸分离区域中的该液态反应组合物的温度比从该第一反应区域中取出的该液态反应组合物的温度高至少8℃。
摘要（英）：

A process for the production of acetic acid comprising: introducing methanol and/or a reactive derivative thereof and carbon monoxide into a first reaction zone containing a liquid reaction composition comprising a carbonylation catalyst, optionally a carbonylation catalyst promoter, methyl iodide, methyl acetate, acetic acid and water; withdrawing at least a portion of the liquid reaction composition together with dissolved and/or entrained carbon monoxide from the first reaction zone; passing at least a portion of the withdrawn liquid reaction composition to a second reaction zone; passing at least a portion of the liquid reaction composition from the second reaction zone into a flash separation zone; wherein the temperature of the liquid reaction composition withdrawn from the first reaction zone is in the range of 170 to 195 DEG C; and the temperature of the liquid reaction composition passed from the second reaction zone to the flash separation zone is at least 8 DEG C greater than the temperature of the liquid reaction composition withdrawn from the first reaction zone.
