Excess molar volumes V{sub m}{sup E} of binary liquid mixtures of trichloroethylene, C{sub 2}Cl{sub 3}H, and tetrachloroethylene, C{sub 2}Cl{sub 4}, with ethylene glycol monomethyl ether, CH{sub 3}OC{sub 2}H{sub 4}OH, diethylene glycol dimethyl ether, CH{sub 3}(OC{sub 2}H{sub 4}){sub 2}OCH{sub 3}, and 1,4-dioxane, [(OC{sub 2}H{sub 4}){sub 2}], have been measured as a function of composition at 298.15 K. The measurements were carried out with a continuous-dilution dilatometer. The excess molar volumes V{sub m}{sup E} are positive over the entire range of composition for the systems trichloroethylene + ethylene glycol monomethyl ether and tetrachloroethylene + ethylene glycol monomethyl ether, + diethylene glycol dimethyl ether, and +1,4-dioxane and change sign from positive to negative for the remaining systems, trichloroethylene + diethylene glycol dimethyl ether and +1,4-dioxane. The measured excess volumes have been compared to previous published data with an effort to assess the effects of replacing the hydroxyl hydrogen by methyl groups, of inserting oxyethylene groups, and of switching linear to cyclic ethers. These results are fitted to the Redlich-Kister equation to estimate the binary coefficients.
