    Abstract: The solid-state disproportionation of potassium benzoate to dipotassium terephthalate and benzene using zinc benzoate catalyst is conducted with the solid reagents dispersed as a slurry in liquid terphenyl diluent. The reactor effluent is water-quenched to obtain a liquid terphenyl phase, a water phase containing dissolved phthalates, and solid spent zinc oxide catalyst. The catalyst is separated by filtration, reslurried in terphenyl, reacted with benzoic acid to regenerate zinc benzoate, and the resultant catalyst slurry recycled to the reactor. The solids-free aqueous phase is contacted with benzoic acid to precipitate terephthalic acid crystals and form soluble potassium benzoate. The crystals are separated by filtration and recovered as a product of the process. The aqueous potassium benzoate solution is concentrated by evaporation and then contacted with hot terphenyl to produce a slurry of solid potassium benzoate in terphenyl for recycle to the reactor. Byproduct benzene is vented from the reactor and/or the effluent quench step.

    Abstract translation: 使用苯甲酸锌催化剂，苯甲酸钾对苯二甲酸二钾和苯的固态歧化用固体试剂作为浆液分散在液体三联苯稀释剂中进行。 将反应器流出物水淬，得到液体三联苯相，含有溶解的邻苯二甲酸酯的水相和固体废氧化锌催化剂。 通过过滤分离催化剂，在三联苯中重新成型，与苯甲酸反应以再生苯甲酸锌，并将所得催化剂浆料再循环至反应器。 不含固体的水相与苯甲酸接触以析出对苯二甲酸晶体并形成可溶的苯甲酸钾。 通过过滤分离晶体并作为该方法的产物回收。 通过蒸发浓缩含水的苯甲酸钾溶液，然后与热三联苯接触，产生固体苯甲酸钾在三联苯中的浆液循环到反应器中。 副产物苯从反应器和/或流出物骤冷步骤排出。

    Abstract: A propylene or ethylene stream containing small quantities of carbon monoxide is contacted with a supported copper oxide catalyst wherein 20 to 95 weight percent of the copper is in the cupric state and the remainder is in a lower valence state. The catalyst is advantageously prepared by treating an oxidized copper oxide catalyst with carbon monoxide or hydrogen.
