Abstract
Shock compression experiments were used to obtain an enthalpy–pressure–volume equation of state of the Rice and Walsh form for liquid CCl4 in 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 1–20 μsec duration of shock experiments even though the equilibrium liquid–solid phase line has been crossed.
