Synthesis of Ionic Liquid from Benzyl Chloride and TMPDA

N,N,N,N-tetramethyl-1,3-propanediamine (0.01 mol) was dissolved in acetonitrile. Benzyl chloride (0.02 mol) was then added after that the mixture was refluxed at 80 °C for 2 h. Product crystallization was performed 3 times using ethanol with a yield of 80% at a melting point of 70 °C. Figure 1 shows a summary of the preparation process. The structure of the synthesized compound was confirmed using FT-IR spectroscopic analysis with KBr pellets on Perkin Elmer in Egyptian Petroleum Research Institute. ¹H-NMR spectroscopy was carried out in dimethyl sulfoxide (DMSO) using a Varian Gemini-200 MHz system.Figure 1
