伯胺喹啉(Primaquin),学名6-甲氧-8-(4'-氨基-1'-甲丁基)氨基喹啉,和扑疟喹啉是同类氨基喹啉衍生物.扑疟喹啉用于检定铬(Ⅵ)、铈(Ⅳ)、金(Ⅲ)、钒(Ⅴ)、碘酸根和高碘酸根曾有报道[1~3],但伯胺喹啉用作无机分析试剂尚未有记载.本文报道在硫酸溶液中伯胺喹啉与八十七种离子的作用,铈(Ⅳ)与伯胺喹啉反应的最适条件和反应灵敏度,有机溶剂对反应产物的作用以及检定铈(Ⅳ)的步骤.本法检铈(Ⅳ)的灵敏度虽不很高,但其选择性甚佳,尤其钪、钇和稀土元素与伯胺喹啉不显色,因此本法适用于混合稀土氧化物中铈(Ⅳ)的检定.

Primaquin in the presence of 0.1 N sulfuric acid reacts with cerium (IV) to give a brightly red-violet coloration which is insoluble in ordinary organic solvonts (18 organic solvents have been tested). The optimum conditions and selectivity of the colour reaction have been investigated in detail.
