Speed of sound data for butyl acetate+benzene,or toluene,or ο-xylene,or m-xylene,or P-xylene bInary mixtures have been measured over the entire range of mole fraction at 308.15 K.The excess isentropic compressibilities(KES)were computed from speed of sound and density data,derived from molar excess volume data.The KES values were analyzed by using graph theoretical approach.The KES values evaluated by graph theory compared reasonably well with their corresponding experimental values.The KSE data were also expressed in terms of Redlich-Kister polynomial equation to derive the coetficients and the standard deviation.
