Density, Electric Conductivity, and Viscosity of Several N‐Alkylpyridinium Halides and Their Mixtures with Aluminum Chloride

Abstract

The specific conductivities of molten N‐methyl‐, N‐ethyl‐, N‐(n‐propyl)‐, and N‐(n‐butyl)pyridinium chlorides and N‐ethylpyridinium bromide were measured from near the melting points to the thermal decomposition temperatures. Conductivities also were measured from 25° to 125°C for mixtures of each of these compounds with aluminum chloride. The composition of the mixtures was 1:2 . In addition, the equimolar melt 1:1 was investigated. Densities and viscosities were measured and equivalent conductivities calculated for each of the 1:2 melts. The viscosities of the mixtures displayed Arrhenius behavior, whereas the conductivities behaved as though a glass transition were involved.
