Abstract

Using a flow calorimetric apparatus, measurements of the isothermal Joule-Thomson coefficient of acetone and chloroform have been made over the range 313.15 to 373.15 K. Values of ( B- T dB dT ) obtained from the measurements are found to be consistent with measurements of the second virial coefficient B. For acetone the measurements are also found to be consistent with values of T 2 d 2B dT 2 obtained from the pressure derivative of the heat capacity. Best-fit equations are given, and parameters for the Stockmayer potential are found.
