Solubilities of some tetra-n-butylammonium salts in liquid ammonia at −37°C. Specific conductances of the saturated solutions

The solubilities of (n-C4H9)4NI, (n-C4H9)4NClO4, (n-C4H9)4NNO3 and (n-C4H9)4NSCN in liquid ammonia at −37°C were determined gravimetrically. Specific conductances of the saturated solutions were measured. Tetra-n-butyl-ammonium nitrate is recommended as supporting electrolyte for electrochemical experiments in liquid ammonia.
