Abstract
Viscosity and density measurements at 25°C on solutions of small straight-chain and cyclic quaternary ammonium iodides, and on methyl and ethyl pyridinium iodide are reported. The derived apparent molal volumes ϕ°ν and viscosity B-coefficients Bη change by constant amounts (0.015 dm3 mol–1 and 0.067 dm3 mol–1 respectively) per CH2 group for all except the pyridinium salts, and are related by the equation Bη= 4.6 ϕ°ν–0.54.
