摘要

Abstract

The physicochemical properties of three different amide-AlCl

based ionic liquid (IL) analogues and their mixtures with copper salt

such as conductivity

viscosity

density and isobutane solubility were determined over a wide range of temperatures. The effects of amide structure

amide/AlCl

molar ratio and CuCl modification on these physicochemical properties were investigated. Results showed that the conductivity of amide-AlCl

based IL analogues was much lower than that of traditional Et

NHCl-AlCl

IL with same ligand/AlCl

molar ratio due to incomplete splitting of AlCl

whereas the density and viscosity of amide-AlCl

based IL analogues were slightly higher. The viscosity of amide-AlCl

based IL analogues was closely related to the amide structure

and followed the order of DMA-AlCl

AA-AlCl

NMA-AlCl

with same amide/AlCl

molar ratio. Meanwhile

the density of amide-AlCl

based IL analogues ranked in the following order:AA-AlCl

NMA-AlCl

DMA-AlCl

. Increasing

the amide/AlCl

molar ratio decreased the conductivity and density

while increased the viscosity. The solubility experiment indicated that the isobutane solubility in NMA-AlCl

was highest than that in two other IL analogues. Under the modification of CuCl

the conductivity

viscosity and density of these IL analogues increased

whereas the isobutane solubility decreased. These results provide the foundation for the development of a suitable IL analogue catalyst for isobutane alkylation.
