【摘要】 采用气相色谱-质谱法(GC-MS)对双氧水生产用乙基蒽醌工作液/氢化液组成进行分析,结合蒽醌工作液制备双氧水的反应原理,形成了乙基蒽醌工作液/氢化液的组成信息表。同样采用GC-MS对戊基蒽醌工作液/氢化液的组成进行分析,结合乙基蒽醌工作液/氢化液的组成信息,推测戊基蒽醌工作液/氢化液中组成的可能结构信息,形成了戊基蒽醌工作液/氢化液组成信息表。该法可以为蒽醌法生产双氧水的企业提供降解物的相关信息,为脱除无效降解物提供参考。更多还原

【Abstract】 A method for the qualitative analysis of compositions of anthraquinone working solution（WS）/hydrogenated working solution（HWS） by gas chromatography-mass spectrometry（GC-MS） was developed. The composition of ethylanthraquinone（eAQ） WS/HWS was identified by GC-MS. Then the samples of amylanthraquinone（AAQ） WS/HWS were analyzed by GC-MS. Combined with the reaction mechanism, the composition of AAQ WS/HWS was inferred. The list of the degradation as well as the intermediate products in the industrial synthesis of H₂O₂ in anthraquinone WS was generated, and the information obtained regarding the composition of the anthraquinone WS/HWS was helpful in identifying and removing the unacceptable degradation products.更多还原
