Nineteen 8-aminoquinoline-5-post azo derivatives are synthesized, and fourteen of them is new compounds. Their color reactions with palladium were studied. The law of effects of substitute groups was found. Two new systems for the spectrophotometric determination of palladium with 5-(4-acetylaminophenylazo)-8-aminoquinoline and 5-(4-methoxyphenylazo)-8-aminoquinoline has been developed, and their conditions were better than those of phenylazo-8-aminoquinoline.
