Orthobaric densities and molar volumes of liquids. Fused ring compounds.
Abstract:(Scanned original: to be superseded.)
ESDU 93029 tabulates density and molar volume for 30 compounds in units of kg/cu m and cu cm/mol respectively from near the melting point to the critical point (although for some compounds the tables are terminated at about 0.8 of critical temperature). The temperature interval is varied from 10 K to 1 K to keep the increments in density reasonably small. The critical density was calculated using the Rackett and Riedel equations and values of critical pressure and temperature adjusted until the predictions of critical density from the two equations were in good agreement. Experimental data for density for each compound were taken from a wide range of sources in the literature and fitted by an equation for log reduced density as 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 the sources of data used. Values at the critical point are also given together with normal boiling and melting points. Vapour pressure data for all the compounds are given in ESDU 93028.
