Abstract

Abstract : The investigated salts form a eutectic mixture which melts below 100 °C, and surface analysis shows the depletion of phosphonium cations. Abstract : We show that both tetraphenylphosphonium bis(trifluoromethylsulfonyl)imide ([PPh4 ][NTf2 ]) and Cs[NTf2 ] are low melting salts of exceptionally high and also very similar thermal stability. This similarity indicates that the thermal stability is dominated by the anion. Moreover, eutectic mixtures of [PPh4 ][NTf2 ] and Cs[NTf2 ] with melting points below 100 °C are presented. Surface analysis of the latter in the liquid state reveals a surprising depletion of [PPh4 ] + ions from the surface.
