用液体比重天平测定了甲基叔丁基醚(MTBE)-苯二元系在293.15～318.15K每间隔5K下的密度值。求得过剩摩尔体积V_m~E。在所测定的每一温度下,V_m~E都是负值,且随温度升高,V_m~E的绝对值稍有减少。实验数据用Redlich～kister方程关联,用线性回归方法求得参数。
The density of methyl tert-butyl ether (MTBE) -benzene binary system at 293.15 ~ 318.15K at 5K intervals was measured by liquid specific gravity balance. Find the excess molar volume V_m ~ E. At each temperature measured, V_m ~ E are negative, and with increasing temperature, the absolute value of V_m ~ E slightly reduced. The experimental data were correlated with the Redlich-Kister equation and the parameters were obtained by the linear regression method.
