| 摘 要： | 在283.15-318.15 K范围内,测定了离子液体四氟硼酸-1-甲基-3-丁基咪唑（BMIBF4）水溶液的密度,计算了其表观摩尔体积^φVB,讨论Pitzer-Simonson方程在278.15～338.15 K温度范围内对离子液体水溶液的适用性,以纯离子液体为参考态,根据实验数据拟合得到了相关的P-S方程体积参数,从拟合偏差得出P-S方程在较稀的BMIBF4离子液体水溶液中偏差较大的结论。

| Abstract: | The density and the viscosity of ionic liquid BMIBF4 aqueous solution were measured at the temperature range from 278.15 to 338.15 K. Values of the apparent molar volumes of aqueous BMIBF4, ^φVB, were calculated. The applicability of Pitzer-simomson （P-S） equation was examined, ranging from 278.15 to 338.15 K in ionic hydroliquid. Taking the pure ionic liquid as reference state, the values of P-S equation parameters were obtained by means of fitting data tested. And from the result, the conclusion was drawn that the P-S equation brought in a little large deviation when it was used to find deviation in the BMIBF4 dilute solution. |
