Descripción
Sumario:The thermal decomposition of calcium propionate, in inert and oxidative atmospheres, has been investigated by thermogravimetry combined with infrared evolved gas analysis; the main volatiles formed during thermal decomposition have been identified. The intermediate and final products have been characterized by infrared spectroscopy, x-ray diffraction, elemental analysis and scanning electron microscopy. The different mechanisms involved in thermal decomposition are discussed as a function of atmosphere and sample structure. The kinetics of the decomposition and the ability of powders to undergo a thermal runaway are also investigated
