Abstract
Heat capacities and dissociation properties of trimethylene oxide and its structure I and structure II clathrate hydrates in the temperature range 85 to 270 K were determined using a Tian–Calvet heat flow calorimeter. The hydrates dissociate incongruently. The heat capacities of the hydrates are similar in magnitude to those observed for other structure I and structure II hydrates. For the structure I hydrate two thermal anomalies were observed. The one centered at 107 K can be identified as due to ordering of the trimethylene oxide dipoles along the [Formula: see text] axes of the cages as suggested by the previous dielectric and nmr relaxation studies. The second centered at 168 K is interpreted as due to trimethylene oxide rich eutectic rather than due to some restructuring of the host lattice as has recently been suggested.
