双季铵盐和钨酸钠催化下双氧水溶液清洁氧化醇和烯烃Oxidation of alcohols and olefins with hydrogen peroxide using Bis-quaternary ammonium and sodium tungstate石先莹
摘 要：利用三种双季铵盐和钨酸钠催化体系,在无有机溶剂条件下,实现了30%过氧化氢水溶液清洁催化氧化环己醇、苯甲醇、环己烯为环己酮、苯甲醛(苯甲酸)、己二酸;考察了不同催化体系的催化性能.实验结果表明,钨酸钠和双季铵盐催化体系能在温和的条件下,催化稀过氧化氢溶液氧化环己醇、苯甲醇、环己烯.其中,己二酸、苯甲酸、苯甲醛、环己酮的最高产率分别为:74.92%,91.37%,94.51%,82.17%.苯甲醇氧化时,随过氧化氢加入量的不同,可以选择性地给出苯甲醛和苯甲酸.关键词：催化氧化;双季铵盐;过氧化氢;过钨酸分类号：O622.31 文献标识码：A文章编号：05)01-0078-04 基金项目：国家自然科学基金资助项目();陕西师范大学研究生创新基金资助项目作者简介：石先莹(1977-),女,陕西户县人,陕西师范大学助教,硕士.魏俊发,通讯联系人:魏俊发,男,陕西师范大学教授,博士. 作者单位：石先莹（陕西师范大学,化学与材料科学学院,陕西,西安,710062）
