The association compounds of TOA and amine extractants exist widely,which were associated through hydrogen bond into 1: 1 compounds. The order of association ability (TOA>DOA>N1923) was consistent to their extraction abilities. Therefore, in different diluents, the association order of HPMBP and TOA was toluene>cyclohexane>n-hexane>benzene.展开更多
文摘以磷钼钒杂多酸H4PMo11V1O40为催化剂、乙酸为溶剂,用双氧水氧化2-甲基萘制备2-甲基萘醌.实验表明：H4PMo11V1O40具有一定的催化活性.通过正交试验和单因素试验考察了催化剂用量、乙酸用量、双氧水用量、反应时间、反应温度等对收率的影响,获得较佳的合成条件：杂多酸∶2-MN（质量比）=7%,乙酸∶2-MN（质量比）=10.5∶1,双氧水∶2-甲基萘（摩尔比）=4.2∶1,较适宜的温度为40~50℃,反应时间为30 min.
