一、蒽醌降解问题概述蒽醌法生产过氧化氢的反应原理和主要降解物一般用图1表示图中各分子式中的R为烷基,我国目前各厂均采用乙基。当溶于溶剂中的乙基蒽醌EAQ(A)或四氢乙基蒽醌H_4EAQ(F) (以下均省略“乙基”二字)在催化剂存在下通H_2时,生成相应的蒽氢醌HEAQ或H_4HEAQ(即B或E),蒽氢醌用O_2氧化,又生成原来的蒽醌,并产出H_2O_2。用水萃取出H_2O_2即为粗产品。得到的蒽醌溶液经后处理(K_2CO_3
First, the overview of anthraquinone degradation problems Anthraquinone production of hydrogen peroxide reaction principle and the main degradation products are generally shown in Figure 1 R in the formula alkyl, China’s current plants are using ethyl. When ethylanthraquinone EAQ (A) or tetrahydroethylanthraquinone H_4EAQ (F) (all abbreviated as “ethyl”) dissolved in the solvent is passed through H 2 in the presence of a catalyst, the corresponding anthracene Hydroquinone HEAQ or H_4HEAQ (ie B or E), anthrahydroquinone with O_2 oxidation, but also generate the original anthraquinone, and output H_2O_2. H 2 O 2 extracted with water is the crude product. The resulting anthraquinone solution after treatment (K_2CO_3
