The main focus is to test different solvents in the Ionic Liquid [C1C1im][NTf2] to see which concentrations they are soluble in. In order to test for solubility, first we synthesize and make our Ionic Liquid. After we synthesize we confirm it through NMR and then we purify it through various processes: Silver Iodide Test, Benzene Azeotrope, and lastly the column filtration. Previously for the solubility tests we used 10 and 20mol% concentrations. The main three solvents used are: CCl4, CS2, and n-pentane. Previous tests proves that “the relative solubility’s of these molecular solutes in C1C1 at room temperature to be in the order n-pentane< CS2< CCl4.” The solubility of CS2, CCl4, and npentane in [C1C1im][NTf2] were studied at 10-20 mol.% concentrations. This study involves the interaction of a nonpolar nonaromatic molecular solute and only the charged group of the IL1. [C1C1im][NTf2] was synthesized and confirmed by NMR spectra. Iodomethane was used in the quaternization step because it is easier to handle and has higher boiling point (i.e., CH3I b.p. 43◦C versus CH3Br b.p. 4◦C). Benzene extraction was performed for the complete removal of the iodine contaminant. Previous solubility test results that “the relative solubility’s of molecular solutes in [C1C1im][NTf2] at room temperature to be in the order n-pentane< CS2< CCl4” are further proved by this experiment.
