This work presents density (ρ), dynamic viscosity (η), refractive index (n_D), and surface tension (γ) experimental data for three pure protic ionic liquids: 2-hydroxyethylammonium acetate ([2-HEA][Ac]), bis(2-hydroxyethyl)ammonium acetate ([BHEA][Ac]), and bis(2 hydroxyethyl)ammonium butyric ([BHEA][Bu]), along with experimental data for two binary systems, as follows: ([2-HEA][Ac] + [BHEA][Ac]) and ([2-HEA][Ac] + [BHEA][Bu]), at a temperature range of T = 278.15 to 343.15 K and atmospheric pressure (101.3 kPa). For the ([2-HEA][Ac] + [BHEA][Ac]) binary system, excess volume and refractive index deviation values are negative, while for the ([2-HEA][Ac] + [BHEA][Bu]) binary system are positive. For the first, there is a volume contraction, with higher probability of ion interactions. For the latter system, an expansive trend and lower ion interactions were found when compared to the ([2-HEA][Ac] + [BHEA][Ac]) system. Viscosity deviations values show a negative behavior for both binary systems studied. These results could indicate the predominance of dispersive forces. Furthermore, for the [2-HEA][Ac] + [BHEA][Ac] system, surface tension deviation values are positive. On the other hand, for the [2-HEA][Ac] + [BHEA][Bu] system this derivative property are negative. From these results, the [2-HEA][Ac] + [BHEA][Ac] binary system could be characterized by presenting prevalent dispersion forces and an unequal distribution of the mixture components between the bulk and interface.

双质子离子液体的二元混合物：密度、粘度、折射率、表面张力和导数特性

这项工作提供了三种纯质子离子液体的密度 (ρ)、动态粘度 (η)、折射率 ( n _D ) 和表面张力 (γ) 实验数据：2-羟乙基乙酸铵 ([2-HEA][Ac]) ，双（2-羟乙基）乙酸铵（[BHEA][Ac]）和双（2-羟乙基）丁酸铵（[BHEA][Bu]），以及两个二元系统的实验数据，如下：（[2 -HEA][Ac] + [BHEA][Ac]) 和 ([2-HEA][Ac] + [BHEA][Bu])，温度范围为T= 278.15 至 343.15 K 和大气压 (101.3 kPa)。对于 ([2-HEA][Ac] + [BHEA][Ac]) 二元体系，过量体积和折射率偏差值为负，而对于 ([2-HEA][Ac] + [BHEA][Bu ]) 二元系统是正的。首先，存在体积收缩，离子相互作用的可能性更高。对于后一种系统，与 ([2-HEA][Ac] + [BHEA][Ac]) 系统相比，发现了更广泛的趋势和更低的离子相互作用。对于所研究的两种二元系统，粘度偏差值都显示出负面行为。这些结果可能表明色散力占优势。此外，对于 [2-HEA][Ac] + [BHEA][Ac] 系统，表面张力偏差值为正。另一方面，对于 [2-HEA][Ac] + [BHEA][Bu] 系统，该导数性质为负。从这些结果来看，
