Molecular Solid Solutions with Steric Complementary Pairing from the Binary Mixtures of 1-Naphthylmethylammonium Alkanoates

A product of the formula AuCd has been isolated by Heycock and Neville by placing a known quantity of gold, together with a considerable excess of cadmium, in a hard glass tube exhausted by a mercury pump, and distilling the mixture for five or six hours at a temperature as high as the glass was capable of withstanding. The composition of the non-volatile residue always approximated closely to that required by the formula AuCd, and the authors concluded that the product was a definite inter-metallic compound. It would appear, however, from the work of Vogel, that these two metals are capable of forming the compounds Au 4 Cd 3 and AuCd 3 . The compound Au 4 Cd 3 forms a series of solid solutions with cadmium, and this author concludes that the product AuCd isolated by Heycock and Neville "dürfte daher als ein kadmium-reicherer Mischkristall der Verbindung Au 4 Cd 3 aus der Reihe Be, seine Zusammensetzung als eine zufällige zu betrachten sein. At the suggestion of Mr. Heycock, the author has commenced a general investigation of the distillation of binary mixtures of metals, one of which at least is readily volatile, in order to ascertain if this method is of general applicability as a means of isolating inter-metallic compounds.

ABSTRACTConvenient methods of correlation and prediction of S+L diagrams exist only for systems forming eutectics. To deal with solid solutions, we have adopted the model of strictly regular solutions of Guggenheim [3–5]. Our key assumption is that values of the Gibbs function of interchange w are different in the two coexisting phases: wS and wL. The assumption is based on the fact that the average interatomic distances R are also different, and this affects the averages of the interatomic (or intermolecular) potentials. The input parameters are enthalpies and temperatures of melting of pure components and any pair of experimental points on the diagram. For a number of binary alloy systems the agreement with the experiment is good. Since we believe in the basic unity of materials (see Chap. 1 in [7]), calcuations have also been made for organic mixtures, again with good results.
