There is increasing interest in piperazine aqueous solutions due to their ability to capture carbon dioxide. This led to the development of piperazine based ionic liquids (ILs). ILs are salts that are liquid at room temperature and have unique properties, such as low vapor pressure. Piperazinium ILs show promise as a possible sequestration medium, although few studies currently exist examining their use for carbon dioxide capture. Here we present results of synthesizing and characterizing 1-methly piperazinium lactate (MPL). Several purification methods were employed to purify MPL including distillation, rotary evaporation, extraction methods, and filtration with activated carbon. The purity of MPL was examined using X-ray photoelectron spectroscopy (XPS), a surface analysis technique that is highly sensitive to IL impurities. By combining the worlds of chemical synthesis and physical chemistry, high purity MPL can be obtained for future carbon dioxide absorption studies.
