    • PURPOSE: A method for hydroxycarbonylating a pentenoic acid is provided to be formed by reacting water and carbon monoxide under a condition of existence of a catalysis containing rhodium and/or iridium and an iodinated or brominated catalytic promoter. CONSTITUTION: The invention discloses pentenoic acid hydroxycarbonylation into adipic acid. More particularly it concerns one pentenoic acid hydroxycarbonylation method involving reaction water and carbon monoxide, in presence of a catalyst comprising at least rhodium and/or iridium and an iodinated or brominated catalytic promoter. In the method, the catalyst is derived at least in part from a previous pentenoic acid hydroxycarbonylation operation. The reaction is effected in the presence of an amount of branched carboxylic diacid having 6 carbon atoms not exceeding 200 grams per kilogram of reaction mixture.
    • 目的:通过使含有铑和/或铱的催化剂和碘化或溴化催化促进剂的存在条件下的水和一氧化碳反应形成戊烯酸羟基羰基化的方法。 构成:本发明公开了戊烯酸羟基羰基化成己二酸。 更具体地说,涉及包含反应水和一氧化碳的一种戊烯酸羟基羰基化方法,所述方法包括至少包含铑和/或铱的催化剂和碘化或溴化催化促进剂。 在该方法中,催化剂至少部分地由先前的戊烯酸羟基羰基化操作得到。 反应在一定量的碳原子数不超过200克/克反应混合物的支化羧酸二酸存在下进行。
