    • An improved process for producing benzophenone-azine in which a catalyst can be removed, recovered and recycled is disclosed. The process comprises the steps of:(a) oxidizing benzophenone-imine with molecular oxygen in the presence of cuprous chloride catalyst to produce an oxidation reaction mixture containing benzophenone-azine;(b) contacting the oxidation reaction mixture obtained in step (a) with an aqueous solution containing ammonium chloride and hydrochloric acid to decompose the remaining benzophenone-imine substantially without causing decomposition of the produced benzophenone-azine and simultaneously to extract the catalyst from the oxidation reaction mixture;(c) separating the oxidation reaction mixture containing benzophenone-azine after the extraction in step (b) to recover benzophenone-azine as a solution;(d) neutralizing the catalyst-containing aqueous solution separated after the extraction step (b) with ammonia and then contacting the neutralized catalyst-containing aqueous solution with benzophenone-imine to extract the catalyst into benzophenone-imine; and(e) separating the benzophenone-imine solution containing the catalyst obtained after extraction in step (d) from the aqueous layer and recycling said solution to step (a) to reuse as a catalyst for step (a), without isolating the catalyst from said benzophenone-imine solution.
    • 公开了可以除去,回收和回收催化剂的二苯甲酮 - 吖嗪的改进方法。 该方法包括以下步骤:(a)在氯化亚铜催化剂存在下用分子氧氧化二苯甲酮 - 亚胺以产生含有二苯甲酮 - 吖嗪的氧化反应混合物; (b)将步骤(a)中获得的氧化反应混合物与含有氯化铵和盐酸的水溶液接触,基本上分解剩余的二苯甲酮 - 亚胺,而不会引起生成的二苯甲酮 - 吖嗪的分解,同时从催化剂中提取催化剂 反应混合物; (c)在步骤(b)中提取后分离含有二苯甲酮 - 吖嗪的氧化反应混合物,以二苯甲酮 - 吖嗪为溶液回收; (d)用氨中和提取步骤(b)后分离的含催化剂的水溶液,然后使中和的含有催化剂的水溶液与二苯甲酮 - 亚胺接触,将催化剂萃取到二苯甲酮 - 亚胺中; 和(e)将步骤(d)中提取后得到的含有催化剂的二苯甲酮 - 亚胺溶液从水层中分离出来,并将所述溶液再循环到步骤(a)中以再利用作为步骤(a)的催化剂,而不将催化剂从 称二苯甲酮 - 亚胺溶液。
