The samples were melted in an oven and kept in an incubator
for 15 min at 100 C to ensure destruction of the crystalline forms.
After removing from the oven, the samples were placed in a dry
static thermal bath with the temperature controlled by a Duratech
tcon Peltier system (temperature range from 5 to 70 C) at a temperature
of 70 C for 1 h (Campos, 2005). After this period, they
were subjected to a temperature of 25 C and readings of the solids
contents taken every 60 s, using low-resolution magnetic pulsed
nuclear resonance equipment (NMR) (Minispeq mq 20, Bruker; Silberstreifen,
Rheinstetten, Germany), until the solids level became
stable.
