Densities of dilute aqueous solutions of CH4, CO2, H2S, and NH3 were determined experimentally at temperatures ranging from 298.15 K to 705 K and pressures to 35 MPa by means of a vibrating tube densitometer. Appropriate techniques were developed for preparation, storing, and handling of solutions a

✦ Synopsis
Heat capacities of dilute aqueous solutions of methane, carbon dioxide, hydrogen sulfide and ammonia were measured at temperatures ranging from 300 K to 705 K and at pressure 28 MPa. The thermodynamic behaviour of aqueous non-electrolytes in the supercritical region is discussed. The results show the expected very large maximum and minimum near the critical density of water. Methods of correlating and predicting values of Vm,2 and Cp,m,2 are explored.
