In the hydrogen peroxide production by anthraquinone working solution containing 2 - Ethyl Anthraquinone (hereinafter referred to as 2 - EAQ), ethyl 2 - 4 hydrogen anthraquinone (hereinafter referred to as 2 - ETHAQ), 2 - EAQ, 2 - ETHAQ with catalytic hydrogenation to obtain an intermediate product, intermediate product by oxidation are hydrogen peroxide, and intermediate products into a 2 - EAQ and 2 -ETHAQ, so as to achieve the purpose of the use of recyclable materials
Tengzhou City Xiangying Analysis Technology Co., Ltd. phase chromatograph by gas XiangyingGC7990plus. Quantitative determination of anthraquinone working solution of process 2 and 2 -ETHAQ, examines the internal standard working curve of the results of quantitative analysis, repeatability and recovery rate were discussed. The results show that the method of anthraquinone working solution analysis with fast, accurate, precision higher characteristic, better than HPLC method.
在蒽醌法生产双氧水的工作溶液中 ,含有 2 -乙基蒽醌 (以下简称 2 - EAQ)、2 -乙基四氢蒽醌(以下简称 2 - ETHAQ) ,2 - EAQ、2 - ETHAQ经催化加氢反应得到中间产物 ,中间产物经氧化得到双氧水 ,同时中间产物又转变成 2 - EAQ和 2 -ETHAQ,从而达到原料循环使用的目的
滕州市翔鹰分析技术有限公司用 XiangyingGC7990plus气相色谱仪，定量测定蒽醌工作液中的 2 -EAQ和 2 -ETHAQ,考察了内标工作曲线的定量分析结果 ,讨论了重复性和回收率的情况 ,结果表明 ,本方法对蒽醌工作液的分析具有快速、准确、精密度高等特点 ,优于HPLC方法。
