用反相离子对色谱方法从工业萘酐中分离出了十几种杂质,并进行了定量测定.在反相色谱体系中,苯酐及马来酸酐等转化成酯和酸,它们可以与萘酐及其它非离子型杂质实现良好的分离.
A dozen of impurities were separated from the industrial naphthalene anhydrides by reversed-phase ion-pair chromatography and quantified. In reversed-phase chromatography, phthalic anhydride and maleic anhydride were converted to esters and acids, And other non-ionic impurities to achieve a good separation.
