Studies on the synthesis of 5-(p-aminobenzylidene)-rhodanine and its properties.
A new analytical reagent 5-(p-aminobenzylidene)-rhodanine (ABR) was synthesized. The acidic dissociation constant of ABR has been determined. The properties, the acid-base behavior of ABR and the reactions of ABR with metallic ions have been studied. The color reactions of the reagent with Pd(II), Au(III), Ag(I), Ru(III), Hg(II) and Cu(II) are studied in detail. The composition of Pd(II)-ABR, Au(III)-ABR and Ag(I)-ABR complexes were discussed.
