By reactions of three kinds of quaternary ammonium salts such as Bu4NCl,(C8H17)3CH3NCl and π-C5H5NC16H33Br with H2WO4 or Na2WO4,a series of quaternary ammonium peroxotungsto phosphate catalysts Q+3{PO4[W(O)O4]3[W(O)O4]}3-(Q+:quaternary ammonium cationR4N+) were prepared and their catalytic activities for expoxidant of styrene were studied with 1,2-dichloroethane as solvent and H2O2 as oxidation.
分别采用不同的季铵盐四丁基氯化铵(Bu4NCl)、三辛基甲基氯化铵(C8H17)3CH3NCl和溴化十六烷基吡啶(π-C5H5NC16H33Br)与钨酸或钨酸钠、磷钨酸反应制得过氧化磷钨杂多酸季铵盐Q3+{PO4[W(O)O4]3[W(O)O4]}3-(Q+:季铵盐正离子R4N+),以其为催化剂、二氯乙烷为溶剂、H2O2为氧化剂氧化苯乙烯,结果发现过氧化磷钨三辛基甲基铵有很好的催化活性,在反应温度55℃、pH=3。

【诗文】:
困睫蒙蒙渴煮茶,系船来叩野人家。
风翻翠浪千畦麦,水漾红云一坞花。
健犊破荒耕荦确,幽禽除蠹啄槎牙。
寻春非复衰翁事,且伴儿童一笑哗。
