Continuous Miscibility from Dilute Solution to Fused Salt: Volumetric Properties of Binary Solutions of Nitrobenzene, 1-Butanol, and Anisole with Tetra-n-Butylammonium Picrate from 298.15 to 371.1 K

Protic Ionic Liquids: Properties and Applications

“…In addition to the EAN studies, in 1956 Kraus investigated ion-pair formation using various electrolytes in solvents, including the PILs butylammonium picrate and triisoamylammonium picrate in benzene . Investigations of binary systems have also been conducted on AILs, such as tetra- n -butylammonium picrate, which is miscible in a number of different solvents …”

“…116 Investigations of binary systems have also been conducted on AILs, such as tetran-butylammonium picrate, which is miscible in a number of different solvents. 120 In the investigation by Kraus, intermediate concentrations of butylammonium picrate and triisoamylammonium picrate, and other non-PIL electrolytes in benzene, were used to observe ion-pair formation. The PILs showed different behavior to other electrolytes because of their ability to form hydrogen bonds, which stabilized ion pairs 116 and led to far lower dissociation constants compared to similar AILs.…”
