Abstract

This investigation was carried out with the aid of the Research Grant of the Iowa Academy of Science. The unusual solvent character of molten acetamide has been reported by Stafford¹. As a solvent for inorganic salts it is very similar to water. The conductance of salts dissolved in acetamide closely resembles that of aqueous solutions². Organic compounds with the exception of some aromatic hydrocarbons are very soluble in molten acetamide. The higher normal amides are quite similar in their solvent properties. In this investigation the freezing point-composition diagrams have .been determined for the binary systems, acetamide with propionamide, butyramide, valeramide, caproamide, and heptamide. The solubility of each amide in acetamide is compared with the ideal solubility calculated from heat of fusion and heat capacity data. The acetamide was obtained from Niacet Chemical Corporation, and purified by the method used by Kumler and Porter". The other amides, Eastman's, were purified by successive crystallizations from ethyl acetate, and washed with dry, cold ether until the melting point remained constant.
