Synthesis and metallochromic properties of some hydrazones of 2-, 3- and 8-hydrazinoquinoline.
Twenty-two new hydrazones were synthesized for evaluation as possible calorimetric reagents for trace determinations of iron, cobalt, nickel, copper and zinc. Spectrophotometric studies revealed that several show promise as sensitive reagents, with possible utility for simultaneous determinations of two or more of the metals. Conclusions regarding geometric structures of some of the hydrazones and chelates were deduced from mole-ratio studies.
