COLOUR SYSTEMS OF MIXED POLYNUCLEAR COMPLEXES OF LANTHANUM-2,7-BISAZOCHROMOTROPIC ACID DYES-ZINC-O-PHENANTHROLINE
【摘要】 <正> In the preceding work we discussed the formation of mixed polynuclear complexes (MPC) of rare earth-arsenazo Ⅲ-copper-o-phenanthroline. This note reports the action rule of various 2, 7-bisazochromotropic acid dyes with different structures in this kind of colour reactions. The experiments showed that only those symmetric 2, 7-bisazochromotropic acid
