Speeds of sound and excess isentropic compressibilities of butyl acetate plus aromatic hydrocarbons
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 mote 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.
