Density-Pressure-Temperature Relations of the Hydrogen Chloride-Propylene System in the Critical Temperature-Pressure Region. Reaction Velocity Near the Critical Temperature

The relation between the density, pressure, and temperature of a 2:1 and of a 1:1 mixture of hydrogen chloride and propylene has been determined over the temperature range 78° to 115 °C. and up to pressures of 115 atm. These determinations are of interest in connection with the investigation of the influence of a "structure" of the liquid state on reaction velocity. Some preliminary measurements of reaction velocity in the critical temperature-pressure region have been made.
