Equation of State of Liquid CCl4to 16 kbarmdash;a Comparison of Shock and Static Experiments

摘要

Shock compression experiments were used to obtain an enthalpyndash;pressurendash;volume equation of state of the Rice and Walsh form for liquid CCl4in the pressure region below 16 kbar. Existing zero pressure data were used to introduce a temperature dependence into the specific heat at constant pressure and into the partial derivative of volume with respect to temperature at constant pressure. Sonic velocities and Hugoniot temperatures calculated from this equation of state agree well with data obtained by other investigators. Carbon tetrachloride apparently exists in the liquid state for the 1ndash;20 mgr;sec duration of shock experiments even though the equilibrium liquidndash;solid phase line has been crossed.
