The method for preparing an alkyl acetylene by the action of an alkyl halide on sodium dissolved in liquid ammonia was modified in certain details. Ethyl and methyl acetylene were prepared and purified and their melting and boiling points determined. Vapor pressures, densities and surface tensions were measured over a considerable temperature range. These properties together with constants calculated from the data are compared with similar data for paraffins and olefines.

The solubility parameters,δH(Tb), of nonreactive permanent gases at their boiling pointsTb(<290 K) are calculated from individually discussed values of their molar enthalpies of vaporization and densities obtained from the literature. These values are tabulated and where available the coefficients of the temperature dependence expressionδH(T)are also tabulated. The trends noted in theδH(Tb)values are dealt with and the values are compared with those reported in the literature and derived from the solubilities of the gases in various solvents. TheδH(Tb)values are shown to correlate linearly with the depths of the potential wells (attractive interaction energies,ε/kB) for binary collisions of the gaseous molecules and with the surface tensions,σ(Tb), of the liquefied gases.
