This laboratory shows teachers and students a save and efficient way to make propane hydrate clathrate. The procedure uses finely ground ice which is called snow and a gas that is at high pressure. In this experiment you will be using propane under approximately 10 atm pressure. Snow will be prepared by using liquid nitrogen to make ice pellets; these will be ground in a coffee grinder. After the propane clathrate hydrate is synthesized, it can be burned as a visual demonstration of the hydrates gas storage capability, or it can be slowly melted to compare its melting curve to that of simple ice. Complete instructions for the lab are available via the link below.
