Ideal-gas enthalpies of formation of butyl vinyl ether, 1,2-dimethoxyethane, methyl glycolate, bicyclo2.2.1hept-2-ene, 5-vinylbicyclo2.2.1hept-2-ene, trans- azobenzene, butyl acrylate, di- tert -butyl ether, and hexane-1,6-diol are reported. Enthalpies of fusion were determined for bicyclo2.2.1hept-2-ene and trans- azobenzene. Two-phase (solid + vapor) or (liquid + vapor) heat capacities were determined from 300 K to the critical region or earlier decomposition temperature for each compound studied. Liquid-phase densities along the saturation line were measured for bicyclo2.2.1hept-2-ene. For butyl vinyl ether and 1,2-dimethoxyethane, critical temperatures and critical densities were determined from the dsc results and corresponding critical pressures derived from the fitting procedures. Fitting procedures were used to derive critical temperatures, critical pressures, and critical densities for bicyclo2.2.1hept-2-ene, 5-vinylbicyclo2.2.1hept-2-ene, trans- azobenzene, butyl acrylate, and di- tert -butyl ether. Group-additivity parameters or ring-correction terms useful in the application of the Benson group-contribution correlations were derived.
