Abstract
The study has been done to produce [C2CN-2-DEEim][DOSS] and [C2CN-Pr-3-
Pheim ][DOSS] and to prove the effect of ether towards viscosity and COz solubility.
The process involves three sections. The first section is alkylation of propanenitrile
imidazole, followed by section two by quaternization reaction to produce ether nitrile
imidazole. In section three, metathesis reaction is done by mixing the ether nitrile
imidazole with Sodium Dioctylsulfosuccinate (DOSS). The characterization of
synthesized ionic liquids was conducted, namely Raman Analysis, water content,
density, viscosity and thermogravimetry measurement. The thermo-physical and phase
behavior properties .of the ionic liquids produced obey the theory which is the thermal
stability ranges between 250°C to 500°C. It has been found that the ether incorporated in
the ionic liquid have an effect towards the viscosity of the ionic liquid and the COz
solibility. Aromatic ring in ether hinders the ionic liquid from achieving maximum COz
absorbed. The objectives were successfully achieved.
