The binary system acetamide and water, investigated by the solubility method, shows the formation of a hydrate of acetamide of composition (CH3CONH2)2H2O. The system is especially characterized by two solubility curves of acetamide in water, one lying ten to twelve degrees below the other. This is due to the two modifications of pure acetamide, with melting points at 80°C. and 69.4°C. In the more dilute solutions, supercooling can be carried to 80° below the crystalizing temperature in sealed tubes. The Binary System acetamide-naphthalene, investigated by the freezing point method shows two eutectics, one compound formation and a pair of immiscible liquids with a critical solution temperature.
