      abstract     = {The stability of 1-methyl-1-propylpyrrolidinium

                      imide (EMIM TFSI) ionic liquids (ILs) at different
                      temperatures (room temperature and 95 °C) was investigated
                      by ion chromatography (IC) hyphenated to a mass
                      spectrometer. The degradation of the cations can be
                      summarized in the following way: The side chain of the main
                      molecule cleaves and reacts subsequently with the main
                      cation molecule to new decomposition products. In addition,
                      the results show that at elevated temperatures more
                      decomposition products are formed.The influence of Li+
                      cation based electrolyte salts, lithium hexafluorophosphate
                      (LiPF6), lithium bis(trifluoromethanesulfonyl) imide
                      (LiTFSI) and lithium perchlorate (LiClO4), on the
                      decomposition of the ionic liquids was analyzed over a long
                      term stability study at room temperature and 60 °C. It was
                      found out that in the mixtures of ILs and electrolyte salt,
                      the same decomposition products were formed like in the pure
                      ILs at the same temperature. Accordingly, there is no
                      influence of the electrolyte salts on the decomposition
                      behavior of the IL cation. The influence of the counter
                      anion on the decomposition of PYR13+ was analyzed as well.
                      It was observed that different decomposition products were
                      detected for PYR13TFSI and PYR13FSI.},
