Excess and unlike interaction second virial coefficients of mixtures of carbon monoxide with propane, n-butane and 2-methylpropane

Measurements have been made of the excess and unlike interaction second virial coefficients for equimolar mixtures of carbon monoxide with propane at five temperatures from 302.23 K to 343.19 K and with n-butane and 2-methylpropane at 348.17 K. The results are compared with the predictions of Tsonopoulos, and Mak and Leilmezs correlations.
