Abstract  

A combination of DSC and high resolution DTG coupled to a gas evolution mass spectrometer has been used to study the thermal properties of a series of Mg/Zn hydrotalcites of formulae MgxZn6-xAl2(OH)16(CO3) 4H2O where x varied from 6 to 0. The effect of increased Zn composition results in the decrease of the endotherms and mass loss steps to lower temperatures. Evolved gas mass spectrometry shows that water is lost in a number of steps. The interlayer carbonate anion is lost simultaneously with hydroxyl units.
