Abstract:

In the present paper new compounds are characterized by TG-DTG-DTA thermal methods in order to investigate the structure-thermostability-degradation mechanism correlation. The results of thermal analysis are indicative of a complex degradation mechanism which is characteristic of every sample, some similarities reflecting the structure influence being also noticed.

The initial degradation temperatures resulting from TG-DTG-DTA led to the estimation of the temperature range of using and storing these compounds which is an useful information if their possible practical applications and of some derivatives as herbicides, plant growth stimulators, fungicides, acaricides are taken into account. Apart from this, the presence of the diazo and azo group in the structure of these new compounds could make possible some useful applications for dying of proteic fibres.

Keywords:

azomethine, diazoaminoderivatives, thermal analysis (TG-DTG-DTA), thermostability, action mechanism.
