合成了3种新型的N-（2-羟乙基）乙二胺乙酸和甲酸铵盐（Hydeten）作为室温离子液体（RTIL）：2-（2-羟乙基氨基）-甲酸乙铵（IL 1a）、2-氨基-N-（2-羟乙基）-甲酸乙铵（IL 1b）和2-（2-羟乙基氨基）-乙酸乙铵（112）。通过元素分析、FT-IR、H-1和C-13 NMR等技术对其结构进行了表征。用TG和DSC技术测定了它们的热性能。研究了IL 1a-b、IL 2和掺杂IL 1 -2的真实的介电（ε“）-频率（ω）、虚介电（ε”）-频率（ω）和电导率（σ（AC））-频率（ω）关系。这些Is还被测试作为溶剂或催化剂在一些有机化合物的合成。(C)2012 Elsevier B.

Three novel acetate and formate ammonium salts of N-(2-hydroxyethyl)-ethylenediamine (Hydeten) were synthesized as room temperature ionic liquids (RTILs) {2-(2-hydroxy ethylamino)-ethanaminium formate (IL1a), 2-amino-N-(2-hydroxyethyl)-ethanaminium formate (IL1b), and 2-(2-hydroxyethylamino)-ethanaminium acetate (112)). Their structures were characterized by using elemental analysis, FT-IR, H-1 and C-13 NMR techniques. Some thermal properties of these Is were determined by using TG and DSC techniques. Real dielectric (epsilon')-frequency (omega), imaginary dielectric (epsilon '')-frequency (omega), and conductivity (sigma(AC))-frequency (omega) relationships of IL1a-b, IL2, and doped IL1-2 were investigated. These Is were also tested as solvent or catalyst in the synthesis of some organic compounds. (C) 2012 Elsevier B.V. All rights reserved.
