ETHER FUNCTIONALIZED IMIDAZOLIUM BASED IONIC LIQUIDS FOR CARBON DIOXIDE REMOVAL

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
