In this study, density, speed of sound and viscosity of binary mixtures of ionic liquids + ethanol have been measured as a function of composition at T = (293.15–313.15) K and atmospheric pressure. The ionic liquids studied were: n -butylammonium acetate (N4Ace), n -butylammonium propanoate (N4Pro), n -butylammonium hexanoate (N4Hex), and n -butylammonium decanoate (N4Dec)}. Excess molar volume
在这项研究中,在 T =(293.15–313.15)K和大气压下,已测量了离子液体+乙醇的二元混合物的密度,声速和粘度与成分的关系 。研究了离子液体为: Ñ -butylammonium乙酸乙酯(N4Ace), Ñ -butylammonium丙酸乙酯(N4Pro), Ñ -butylammonium己酸酯(N4Hex),和 Ñ -癸酸正丁基铵(N4Dec)}。过大的摩尔体积\(V _ \ text m}} ^ \ rm E}} \),等熵压缩率偏差,\(\ Delta \ kappa _ \ text S}} \},粘度偏差,从实验结果中获得了\(\ Delta \ eta \)和激活粘性流的多余吉布斯能量\(\ Delta G ^ * \ rm E}} \\)并与Redlich–Kister多项式方程相关。合成了离子液体,并使用1 H-NMR,13C-NMR和FT
