摘要
采用分步加入原料-分步酸化、回流煮沸-乙醚萃取的方法合成了Keggin型磷钼钒杂多酸,并对其进行元素分析和红外光谱表征,结果表明此法合成的杂多酸产率可达90%以上。
The Keggin -type heteropoly acid were synthesized by modified literature method, in whith reactive raws were acided and then re.fluxed, ethyl ether - extracted. Their structures were determined using IR and ICP. The result indicates that yield of heteropoly acidss were improved.
