Thermal behaviour study of solid state compounds of manganese (II), zinc (II) and lead (II) with cinnamic acid

Abstract

Foram preparados em meio aquoso os cinamatos de manganês, zinco e chumbo. Na caracterização, bem como no estudo da decomposição térmica desses compostos, foram utilizados a termogravimetria, termogravimetria derivada (TG, DTG), calorimetria exploratoria diferencial (DSC), difração de raios-x e complexometria.

Compounds of cinnamic acid with manganese, zinc and lead have been prepared in aqueous solution. Thermogravimetry, derivative thermogravimetry (TG, DTG), differential scanning calorimetry (DSC), X-ray diffraction and complexometry have been used in the characterization as well as in the study of the thermal stability and interpretation concerning the thermal decomposition.
