Crystallisation of organic hydrates by sublimation

Abstract

A series of five organic molecules with known crystalline hydrates were sublimed under vacuum in the presence and absence of water. In two systems, crystals of the hydrate could easily be grown from sublimation. Generally, a mixture of hydrated and anhydrous forms were obtained from sublimation. In several cases, an increase in the quantity of water added to the sublimation system resulted in an increase in water content of the sublimed crystals. Competition studies demonstrated that transfer of water can take place between hydrate and anhydrous forms during a sublimation experiment.
