On Hydrating Agents (Supplement)

Abstract

Basing upon the heat of formation, the number of hydrate and the crystal density previously measured and reported, the author made a comparison of the structure I with the structure II, and reached the conclusion that the structure II hydrate could more easily crystalize than the structure I and that as the number of hydrate increased the former was superior to the latter when used in the hydrate cycle.
By using the boiling point and the critical temperature of the hydrating agent, the author could draw a graph, which is accurate enough in practical use to determine unknown temperature and pressure of hydrate formation.
