During the present reportinB period, experimental measurements were obtained on the solubility of :arbon monoxide (CO) in selected hydrocarbons using our static type equilibri'_m ceil. Binary mixtures involving CO + n-eicosane (n-C20), n-octacosane _n-C28), and n-hexatricontane (n-C36) were studied at temperatures from 22_.2 to _23.2 K and pressures to 104 bar. These data were analyzed using the Zsave-Redlich-Kwong and Peng-Robinson equaUions of state. While a single inter=_c_ion parameter, Cij , describes the n-C20 and n-C28 measurements within 0.CO-in mole fraction over the full temperature range, :emperature dependent :arameters are required to adequately fit the n-C36 data. The present data are in reasonable agreement with the earlier measurements of Huang and cowor::ers: in _eneral, deviations within 0.004 in mole fraction are observed.
