Synthesis And Spectral Properties Of Some New Derivatives Of 4-Aminoantipyrine Azo Dyes Part I
Abstract
Abstract
This study involves the synthesis of three new azo dyes 4-aminoantipyrine with 8-hydroxyquinoline (L1) , 2- thiobarbituric acid (L2) and 2-methylthiobarbituric acid (L3) . The characterization of dyes have been described by C.H.N. , I.R. and visible . spectroscopic techniques , the electronic spectra of these azo dyes were studied in term of acid-base properties at different pH values ( 0.65- 12 ) ,which includes establishing isobestic point , mechanism and determination of protonation and ionization constants of dyes. The effect of solvents of different polarities on the electronic spectra were also investigatedDownloads
