Thermal Decomposition of Unsaturated Nickel(II) Dicarboxylates

详细

Thermal decomposition of nickel hydrogen carboxylates (NHCs) of unsaturated dicarboxylic acids has been studied by the TGA/DTA method in combination with DSC analysis and mass spectrometry of gaseous thermolysis products. The temperature ranges of the key stages of the thermal decomposition of NHCs were determined: (1) dehydration, 50–275°C; (2) polymerization of dehydrated carboxylate, 125–360°C; (3) decarboxylation, 290–450°C. A conclusion has been made that these stages can overlap one another and proceed simultaneously.
