摘要：

The addition of a densitometer to the flow calorimeters developed earlier made possible the simultaneous measurement of heats of mixing (H(m)E) and solution densities. The availability of H(m)E and density data measured at the same temperature-pressure coordinates should be useful in developing more accurate models of fluid behavior in the critical region. The instrument was used to measure H(m)E and density values for the systems n-hexane + CO2 and neopentane + CO2.
