Equilibrium constants for the Diels-Alder reaction of 9-chloroanthracene with tetracyanoethylene have been determined in the pressure range 0-970 kg cm-2 in 1,2-dichloroethane at 298 K and the value of the reaction volume (-20.6±1.5 cm3 mol-1) has been compared with the difference in partial molar volume of the dienophile (107.8±0.2), diene (170.7±0.5) and adduct (255.5±1.5 cm3 mol-1).
