During the present reporting period, experimental measurements were obtained on the solubility of carbon monoxide (CO) in selected hydrocarbons using our static type equilibrium cell. Binary mixtures involving CO + n-eicosane (n-C{sub 20}), n-octacosane (n-C{sub 28}), and n-hexatricontane (n-C{sub 36}) were studied at temperatures from 323.2 to 423.2 K and pressures to 104 bar. These data were analyzed using the Soave-Redlich-Kwong and Peng-Robinson equations of state. While a single interaction parameter, C{sub ij}, describes the n-C{sub 20} and n-C{sub 28} measurements within 0.004 in mole fraction over the full temperature range, temperature dependent parameters are required to adequately fit the n-C{sub 36} data. The present data are in reasonable agreement with the earlier measurements of Huang and coworkers in general, deviations within 0.004 in mole fraction are observed.
