摘要
过氧化氢(H_(2)O_(2),又名双氧水)是一种重要的绿色化工原料,其作为强氧化剂、漂白剂、消毒剂等在化工、纺织、造纸、国防、电子、医疗、环境保护等行业中有着广泛的应用。本文介绍过氧化氢的5种生产方法,包括电解法、异丙醇法、氧阴极还原法、氢氧直接合成法以及蒽醌法,对蒽醌法过氧化氢工艺原理进行详细分析,主要包括2-乙基蒽醌(EAQ)和四氢-2-乙基蒽醌(H_(4)EAQ)氢化、2-乙基蒽氢醌(EAQH_(2))和四氢-2-乙基蒽氢醌(H_(4)EAQH_(2))氧化、过氧化氢萃取、工作液净化回收,探讨了生产过程中可能存在的蒽醌中芳环的氢化、羰基键的氢解以及氧化降解等多种副反应。结合工程实践,利用DCS系统对蒽醌法生产过氧化氢的工艺过程进行全程监测,为蒽醌法的工业化应用提供一定的参考。
Hydrogen peroxide(H_(2)O_(2),also known as hydrogen peroxide solution)is one of important cleanest chemical materials,which is widely used in the chemical,textile,papermaking,defense,electronic,medical,environmental protection and other industries as oxidant,bleaching agent,disinfectant,etc.This paper introduced the various production methods of hydrogen peroxide,including electrolytic method,isopropanol route,oxygen cathodic reduction,direct synthesis from hydrogen and oxygen,anthraquinone process.The technology principle of hydrogen peroxide produced in anthraquinone auto-oxidation method was analyzed,which mianly included 2-Ethyl-9,10-anthraquinone(EAQ)and 6-ethyl-1,2,3,4-tetrahydroanthracene-9,10-dione(H_(4)EAQ)hydrogenation,2-Ethyl-9,10-anthrahydroquinone(EAQH_(2))and 6-ethyl-1,2,3,4-tetrahydroanthracene-9,10-Diol(H_(4)EAQH_(2))oxidation,hydrogen peroxide extraction,working solution purification and recycling.The possible side reactions such as hydrogenation of aromatic ring,hydrogenolysis of carbonyl group and oxidation degradation of anthraquinones in the production processin detail were discussed,which provided a certain reference for the application of hydrogen peroxide production technology by anthraquinone process.
