Abstract This work is inserted in a research program that consists mainly in the experimental and theoretical study of gas/liquid solubility in ionic liquids (ILs). In this study the experimental data of hydrogen sulfide solubility in ammonium-based ionic liquids, namely 2-hydroxyethylammonium acetate [2-HEA][Ace], bis(2-hydroxyethyl)ammonium acetate [B-2-HEA][Ace] and 2-hydroxyethyldiethylammonium hydrogen diacetate [2-HEDEA][H(Ace)2], were determined using a volumetric method in the 298 K to 318 K temperature range and at atmospheric pressure. The ionic liquids are functionalized with the OH group in the ammonium-based cations, in order to study the influence of hydroxyl group in the formation of hydrogen bonds between the IL-IL and IL-gas. The data gathered is modelled with the Cubic Plus Association Equation of State (CPA EoS), considering the association schemes four-sites (4C) for hydrogen sulfide and two-sites (2B) for the ILs ([2-HEA][Ace], [B-2-HEA][Ace] and [2-HEDEA][H(Ace)2]).

H2S 在铵基离子液体中的溶解度

摘要 这项工作被纳入一项研究计划，该计划主要包括气/液在离子液体 (ILs) 中的溶解度的实验和理论研究。本研究中硫化氢在铵基离子液体中溶解度的实验数据，即2-羟乙基乙酸铵[2-HEA][Ace]、双(2-羟乙基)乙酸铵[B-2-HEA][Ace]和2-羟乙基二乙基二乙酸氢铵 [2-HEDEA][H(Ace)2]，在 298 K 至 318 K 温度范围和大气压下使用体积法测定。离子液体用铵基阳离子中的 OH 基团进行功能​​化，以研究羟基对 IL-IL 和 IL-gas 之间氢键形成的影响。收集到的数据是用立方加关联状态方程 (CPA EoS) 建模的，
