Abstract: Bu çalışmada, 5-amino-4-arilazo-3-metil-1H-pirazol türevleri diazolanmış ve malononitril ile kenetlenerek (4-arilazo-3-metil-1H-pirazol-5-ilazo)malonnitril bileşikleri elde edilmiştir. Elde edilen bileşikler, hidrazinmonohidrat ile reaksiyona sokularak bir seri 4-(4'-arilazo-3'-metil-1'H-pirazol-5'-ilazo)-3,5-diamino-1H-pirazol türevleri sentezlenmiştir. Sentezlenen disazo boyarmaddelerin yapıları element analizi ve spektrofotometrik yöntemler kullanılarak aydınlatıldı. Sentezlenen boyarmaddelerin görünür bölge absorpsiyon spektrumları üzerine değişik çözücü, asit ve baz etkileri incelendi.
In this study, 5-amino-4-arylazo-3-methyl-1H-pyrazoles were diazotised and coupled with malonitrile to give (4-arylazo-3-methyl-1H-pyrazole-5-ylazo)malononitrile. The synthesized components were then reacted with hydrazine mono hydrate to give 4-(4'-arylazo-3'-methyl-1'H-pyrazole-5'-ylazo)-3,5-diamino-1H-pyrazoles. The structure of synthesized disazo dyes were characterized by elemental analysis and spectral methods. The effect of varying solvents, acid and base upon the absorption spectra of resultant dyes has been investigated.
