In this communication, we report equilibrium pressures for nitrous oxide clathrate hydrates in the temperature range of (266.7 to 285.1) K and for clathrate hydrates of carbon dioxide in the temperature range of (264.5 to 271) K. The experimental data have been measured using isochoric pressure search methods. It is shown that the dissociation temperatures of nitrous oxide clathrate hydrates are approximately 2.3 K higher than the dissociation temperatures of carbon dioxide clathrate hydrates at given pressures.
