Excess volumes (V-E) of binary mixtures of ethyl acetate with toluene and its o- and p-chloro derivatives have been determined from density measurements from 283.15 to 303.15 K over the entire composition range. Excess volumes are negative for all mixtures at all temperatures. The V-E values are close to zero for the ethyl acetate + toluene system. The values decrease in the order toluene, o-chlorotoluene, and p-chlorotoluene. The effect of temperature on the excess volume is (partial derivative V-E/partial derivative T)(p), being generally negative.
