    Abstract: A process for oxidizing ethyl-substituted benzenes to benzene carboxylic acids in a solvent mixture consisting of acetic acid and water using a cobalt carboxylate and manganese carboxylate catalyst and maintaining the concentration of unreacted ethylsubstituted benzene in reaction mixture at a value of at least 5 percent by volume on a solvent-free basis.

    Abstract translation: 使用羧酸钴和羧酸羧酸钴催化剂将乙基取代的苯氧化成由乙酸和水组成的溶剂混合物中的苯羧酸的方法,并将反应混合物中未反应的乙基取代的苯的浓度保持在至少5 以无溶剂为基础的体积百分数。
