Abstract
The presence of trichlorofluoromethane hydrate in bulk water and in water-in-oil emulsions has been detected by differential scanning calorimetry. Hydrates have been observed during the heating of samples introduced into the head of a calorimeter. The amount of hydrate crystals was found to be dependent on the sample volume, the temperature reached during the cooling performed prior to the heating, and the time spent at the subambient temperature. These results confirm the kinetic aspects of hydrate formation and show that ice crystals may act as hydrate nucleating agents. Furthermore, two polymorphic forms are suspected to exist, but this must be confirmed by another technique.
