  Processes for producing terephthalic acid are disclosed, the processes comprising combining in a reaction medium p-xylene, a solvent comprising water and one or more saturated organic acids having from 2-4 carbon atoms, and an oxygen-containing gas, at a temperature from about 135° C. to about 165° C., in the presence of a catalyst composition comprising cobalt atoms and manganese atoms, with bromine atoms provided as a promoter. The amount of cobalt used may be from about 1,800 ppm to about 6,000 ppm, with respect to the total weight of the liquid in the reaction medium, and the weight ratio of cobalt to manganese may be from about 40 to about 400. The processes according to the invention produce terephthalic acid as a precipitated reaction product, with typically no more than about 10 ppm 2,6-dicarboxyfluorenone produced, with respect to the weight of the terephthalic acid produced, or no more than about 20 ppm 2,6-dicarboxyfluorenone, with respect to the total weight of the reaction medium, per batch or upon one pass through a reactor. The terephthalic acid so produced may be further purified by one or more additional oxidation reactions, without the need for expensive hydrogenation purification processes.

  公开了生产对苯二甲酸的工艺，该工艺包括在反应介质中混合p-二甲苯、包含水和一个或多个具有2-4个碳原子的饱和有机酸的溶剂以及含氧气体，在存在钴原子和锰原子的催化剂组合物的情况下，以溴原子作为促进剂，在温度约为135℃至165℃之间进行。使用的钴量可以是相对于反应介质中液体的总重量约为1,800 ppm至6,000 ppm，而钴与锰的重量比可以是约40至400。本发明的工艺产生沉淀的对苯二甲酸作为反应产物，通常不会产生超过约10 ppm的2,6-二羧基芴酮，相对于所产生的对苯二甲酸的重量，或不超过约20 ppm的2,6-二羧基芴酮，相对于反应介质的总重量，每批次或通过反应器的一次通行。因此生产的对苯二甲酸可以通过一个或多个附加的氧化反应进一步纯化，而无需昂贵的氢化纯化工艺。
