The published experimental P-rho-T data for 21 ethers, 10 ketones, 9 aldehydes, 9 carboxylic acids, and 25 esters (74 substances) in the liquid phase are summarized and reviewed, and the parameters of the Tait equation are given for 73 substances considered. This equation allows the calculation of smoothed values of either the volume ratio, V(P)/V(P-ref), and related properties (relative density, rho(P)/rho(P-ref), compression, {1 - V(P)/V(P-ref)}) or, using density data at atmospheric pressure (P-ref - 0.1 MPa) or at saturation (P-ref = P-sat), the liquid density of the substances over a temperature and pressure range.
