摘要/Abstract

摘要： Speed of sound data for butyl acetate+benzene, or toluene, or o-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 (K_S^E) were computed from speed of sound and density data, derived from molar excess volume data. The K_S^E values were analyzed by using graph theoretical approach. The K_S^E values evaluated by graph theory compared reasonably well with their corresponding experimental values. The K_S^E data were also expressed in terms of Redlich-Kister polynomial equation to derive the coefficients and the standard deviation.
