Özet

Thermal behaviour of substituted monoazo dyes I-XVI, have been investigated by means of differential thermal analysis (DTA) and thermogravimetry (TG). The thermal stabilities of these dyes have been determined using the DTA and TG curves and the influence of the substituents and intramolecular hydrogen bonds on the DTA and TG curves of the dyes together with the melting points were also examined.
