Acetonitrile can be successfully dried by means of pervaporation with PVA membranes. A substantial amount of data is required to descriptionbe the behaviour of the system with the solution-diffusion model. Wijmans and Baker have formerly proposed a method to descriptionbe pervaporation systems with permeation data only. This method was used to attempt to descriptionbe the pervaporative behaviour of acetonitrile-water systems in the vicinity of the thermodynamic azeotrope. The method was found to be sufficiently accurate for interpolation between experimental data.
