Abstract

A series of bis(trifluoromethylsulfonyl)imide hydrophobic monocationic ionic liquids (ILs) with alkyl and siloxane substituents in the imidazolium cation were synthesized and their physicochemical properties were studied. The effect of the substituent nature in the imidazolium cation on the properties of the synthesized ILs was studied. The ILs obtained are characterized by a working temperature range from −70 to 300 °C, viscosity values in the range of 65–184 cSt (30 °C), and surface tension ranging from 23 to 31 mN m⁻¹ (20 °C), being promising lubricants for modification of hydrophobic solid surfaces.

咪唑阳离子中取代基性质对单阳离子离子液体性质的影响

合成了咪唑阳离子上以烷基和硅氧烷为取代基的双（三氟甲基磺酰基）亚胺疏水单离子液体，并对其理化性质进行了研究。研究了咪唑阳离子中取代基的性质对合成的苯胺类化合物性能的影响。所获得的液态润滑剂的工作温度范围为- 70至300°C，粘度值范围为65-184 cSt(30°C)，表面张力范围为23至31 mN m - 1(20°C)，是改性疏水固体表面的有前途的润滑剂。
