Název v původním jazyce

Use of emanation thermal analysis and evolved gas analysis in thermal study of zinc(II) benzoate complex compounds

Popis výsledku v původním jazyce

Thermal behaviours of three zinc(II) benzoate complex compounds (two new with caffeine and urea), namely Zn(C6H5COO)(2), Zn(C6H5COO)(2)center dot caf(2), Zn(C6H5COO)(2)center dot u(2), were characterized by using thermogravimetry (TG/DTG), differential thermal analysis (DTA), evolved gas analysis (EGA) with mass spectrometry (MS) detection and emanation thermal analysis (ETA). Temperature intervals of the stability of the compounds as well as the mechanisms of their thermal degradation were determined.From TG and DTA results it followed that the oxidative degradation of urea with CO2 or caffeine with CO2 from the investigated Zn(II) benzoate complex compounds takes place as the first step of their thermal degradation. In the second step of thermal degradation diphenylketone was release. The evolved gas analysis has been used to determine intermediate products of thermal degradation and temperature ranges of their evolution from the samples.
