Vapor‐liquid and liquid‐liquid vapor phase behavior of the carbon monoxide‐propane and the carbon monoxide‐ethane systems

Abstract Low‐temperature vapor‐liquid phase data are reported for the carbon monoxide‐propane and the carbon monoxide‐ethane systems. The data for the carbon monoxide‐propane system are reported at eight temperatures ranging from −125°C to +50°C., with pressure up to 2,000 lb./sq. in. abs., those for the carbon monoxide‐ethane system are reported at four temperatures from −100°C to 0°C., with pressures ranging up to the critical locus. Liquid phase immiscibility was observed at low temperatures in both the carbon monoxide‐ethane and the carbon monoxide‐propane systems. The pressure‐temperature loci for these two systems in liquid‐liquid vapor equilibrium were determined.
