ESDU 99008 tabulates from near the melting point to the critical point density in kg/cu m and molar volumes in cu cm/mol, both at 10 K intervals, for 41 halogenated alkylbenzenes and 4 halogenated styrenes. For each compound, a further table gives at specified Celsius temperatures the density, molar volume and their derivatives with respect to temperature. The critical density was calculated using the Rackett and Riedel equations, and values of critical temperature and pressure were adjusted to give the best correlation of experimental results extracted from the literature for both the density data given here and the vapour pressure data given for these compounds in ESDU 99007. The equation used to fit the density data related log reduced density to a polynomial function of reduced temperature. Values for the coefficients in the equation are tabulated for each compound together with estimates of the accuracy of the predictions using them and a list of sources of data used. Values at the critical point are also given together with normal boiling and melting points.
