| Abstract: | The thermal decomposition of zinc salicylate (HOC 6H 4CO 2) 2Zn, was studied by thermogravimetric analysis. The products of thermal decomposition at various stages were characterized by infrared spectrometry, powder X ray diffraction, gas chromatography and mass spectrography. The thermal decomposition of (HOC 6H 4CO 2) 2Zn proceeded in two stages: (HOC 6H 4CO 2) 2Zn(OC 6H 4CO 2)ZnZnO, C, C 6H 5OH, diphenylene oxide, xanthenone, etc. The thermal decomposition reaction mechanism was discussed. |
