DTA heating rates

Differential thermal analysis under vacuum (DTA heating rate 20 C/min.) as shown in Figure 9 indicated three endotherms with peak temperatures at -98 C, -122 C and -182 C. The first two endotherms correspond to loss of water of hydration and the one at 182 C to melting. [Pg.247]

Fig. 1. Trimesic Add (i) solid state reactions as recorded by DTA (heating rate 10 °C/min, in air). Together with parallel high-temperature X-ray diffraction studies, these results lead to identification of 1 as the a p phase change and to 2 as the incompletely resolved combination of the P y quasiphase change, vaporisation and melting (taken from Ref.
