Temperature dependence measurements and molecular interactions for ammonium ionic liquid with N-methyl-2-pyrrolidone

Measurement and correlation of physical properties of aqueous solutions of tetrabutylammonium hydroxide, piperazine and their aqueous blends

“…Overall it was found that density decreases with an increase in temperature. The same trend was found by Kavitha et al and Kurnia et al [37,38].…”

Speed of sound of ionic liquids: Database, estimation, and its application for thermal conductivity prediction

“…(3) Based on the initial search results, the database is expanded by the inclusion of new publications and references contained in the selected publications. Finally, the speed of sound data are collected and tabulated from the publication pool which including totally 96 ILs, containing 51 cations and 23 anions (see Supporting Information for more detail) . In Supporting Information Table S1, the abbreviation of ionic liquids, full name of ionic liquids, CAS registry number, molecular formula, molecular structure, and molar mass were listed.…”

Densities, viscosities, and excess properties of binary mixtures of two imidazolide anion functionalized ionic liquids with water at T= (293.15 to 313.15) K

“…The densities of the two studied systems appearing maximum value near x 1 % 0.20 seem to suggest that the interaction water and ion pair of [HDBU]IM or [BDBU]IM reaches the maximum. According to literature [31], the decrease in density values of the studied systems with x 1 may be due to a decrease in the ion pair interactions between IL and water. As can be seen from table 2 and figure S3, the density values of the mixtures always decrease with the increasing temperature.…”

“…figure 1a and b, respectively. As can be seen in figure 1, the V E values of the two systems show negative deviations over the entire mole fraction range, indicating that both the packing efficiency and the specific interactions between IL and water are dominant [31,32]. The packing efficiency of the studied systems may be due to the difference in molecular volume between the ILs and water, which leads to the accommodation of water in the interstice of the ILs networks and the contraction in volume of mixture.…”
