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 （ Ks^E ） were computed from speed of sound and density data, derived from molar excess volume data. The Ks^E values were analyzed by using graph theoretical approach. The Ks^E values evaluated by graph theory compared reasonably well with their corresponding experimental values. The Ks^E data were also expressed in terms of Redlich-Kister polynomial equation to derive the coefficients and the standard deviation.
为丁基 acetate+benzene 的健全数据的速度，或甲苯，或 o 二甲苯，或 m 二甲苯，或 p 二甲苯二进制代码混合物在 308.15 K 在鼹鼠部分的全部范围上被测量了。过量 isentropic 压缩的可能性(KES ) 从声音和密度数据的速度被计算，源于臼齿的过量音量数据。KES 价值被使用图分析理论途径。KES 价值由与他们的相应试验性的价值相当作比较很好的图理论评估了。KES 数据也以 Redlich-Kister 多项式方程被表示导出系数和标准差。
