摘要： The present application relates to a method for photochlorination, and specifically to photochlorination by a photochemical reaction of an aromatic compound with gaseous chlorine so as to prepare a trichloromethyl-substituted benzene, and to a method using bis-(trichloromethyl)-benzene as the trichloromethyl-substituted benzene to prepare by further reaction bis-(chloroformyl)-benzene. Through the control of temperature, illuminance and consumption of gaseous chlorine, the method of this application can greatly improve the purity of trichloromethyl-substituted benzene and further prepare polymer-grade bis-(chloroformyl)-benzene with low cost. The present application also relates to a method for purifying trichloromethyl-substituted benzene, and specifically to a method for purifying trichloromethyl-substituted benzene via molecular distillation. The present application further relates to a photochlorination reactor for use in photochlorination reactions (such as those of the present application).
摘要翻译：本申请涉及一种光氯化方法，具体涉及通过芳族化合物与气态氯的光化学反应进行光氯化，以制备三氯甲基取代的苯，以及使用双（三氯甲基） - 苯作为三氯甲基的方法通过进一步反应双 - （氯甲酰基） - 苯制备。通过控制气态氯的温度，照度和消耗量，本方法可以大大提高三氯甲基取代苯的纯度，进一步制备聚合物级双（氯甲酰基） - 苯，成本低廉。本申请还涉及三氯甲基取代的苯的纯化方法，特别涉及通过分子蒸馏纯化三氯甲基取代的苯的方法。本申请还涉及用于光氯化反应的光氯化反应器（例如本申请的那些）。

摘要： A method for preparing chlorine gas through catalytic oxidation of hydrogen chloride is carried out by one-time hydrogen chloride feeding and multi-stage oxygen feeding, one-time oxygen feeding and multi-stage hydrogen chloride feeding, or both, returning a product gas stream without separation thereof, and optionally carrying out heat insulation means. In the present invention, excessive reaction heat concentration is prevented, therefore, the method of the present invention is a chlorine gas recovery method implemented through the Deacon catalytic oxidation of hydrogen chloride that may be industrialized.
