摘　　要：为了改进蒽醌法生产H2O2的由重芳烃(AR)和磷酸三辛酯(TOP)组成的工作液的氢效,考察了2-乙基蒽醌(2-EAQ)在添加邻甲基环己基醋酸酯(2-MCHA)或二异丁基甲醇(DIBC)的三组分工作液(AR+TOP+2-MCHA和AR+TOP+DIBC)中的溶解度,并分析了三组分工作液的密度、黏度、界面张力和H2O2的分配系数,从中选取了体积比为75∶20∶5的AR+TOP+2-MCHA和体积比为75∶5∶20的AR+TOP+DIBC 2种性能优异的工作液,采用微反装置评价了其氢效。结果表明,与两组分工作液相比,2-EAQ在三组分工作液中的溶解度得到了显著提高;与两组分工作液的氢效5.65g/L相比,三组分工作液的氢效得到显著提高,分别达到12.53和11.31g/L。In order to improve the hydrogen efficiency of working solution containing two components of heavy aromatics（AR）and trioctyl phosphate（TOP）for H2O2 production by anthraquinone method,the solubilities of 2-ethylanthraquinone（2-EAQ）in working solutions of AR＋TOP added acetic acid（2-methylcyclohexyl）ester（2-MCHA）or 2,6-dimethyl-4-heptanol（DIBC）were measured.The density,viscosity,surface tension of AR＋TOP＋2-MCHA and AR＋TOP＋DIBC solutions,and the distribution coefficient of H2O2 in these solutions were analyzed.The AR＋TOP＋2-MCHA and AR＋TOP＋DIBC solutions with the volume ratios of 75∶20∶5and 75∶5∶20,respectively,were chosen as the working solutions,which possessed good properties for production of H2O2. Then their hydrogen efficiencies were evaluated in a microreactor.The results showed that compared with the AR＋TOP working solution,whose hydrogen efficiency was 5.65g/L,the hydrogen efficiencies of the two new working solutions were significantly improved,reaching 12.53 and 11.31g/L,respectively.
