ABSTRACTMaster of Science ThesisSYNTHESIS OF MONOAZO COMPOUNDS OF SOME SUBSTITUE ANILINEWİTH BENZENE-1,3,5-TRIOL INVESTIGATION OF THEIR TAUTOMERICEQUILIBRIUMSerap YILDIRIMAnadolu UniversityGraduate School of SciencesChemistry ProgramSupervisor: Asst.Prof.Dr. Halil BERBER2007, 118 pagesIn the first stage of the study, different aniline derivation were synthetized by usingappropriate diazonium salts. Azo-coupling reaction was carried out using benzene-1,3,5-trioland substitue aniline derivations and dyestuffs of monoazo were obtained.1The structures of substituted compounds were characterized by using H- NMR,13C-NMR, IR and elementary analysis techniques.In the second stage, the tautomeric structures of obtained compounds were searched.The tautomeric forms were searched in DMSO, CH3CH2OH, CHCl3, benzene, cyclohexanesolutions, in solvent affect, acidic and basic media at 25±1oC, 35±1oC ve 45±1oC wereexamined.Keywords: Substituted Aniline, Benzene 1,3,5-triol, Dyestuffs of Monoazo, Tautomerism,UV Spectroscopic Determination
