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 solubilities of anhydrous CaSO4 and CaSO4.2H2O in concentrated aqueous solutions of NaCl at a series of temperatures—25 °C, 30 °C, 40 °C, and 50 °C, have been determined. It was found that the transition temperature for the reaction[Formula: see text]which in pure water has a value of 42 °C, is shifted progressively to lower temperatures with increasing NaCl concentration. It was also found that the variation of the transition temperature with NaCl concentration could be adequately represented by the equation[Formula: see text]where ΔG, ΔH, and ΔS are the Gibbs free energy, enthalpy, and entropy of the reaction and P0 and P are the vapor pressures of pure water and the solution respectively at the absolute temperature T.
