Abstract
A process is disclosed for the separation of p-fluoroaniline from a mixture, containing aniline and p-fluoroaniline, by contacting the mixture with a mineral acid in the presence of an organic solvent. The corresponding salt of p-fluoro-aniline is insoluble and can easily be isolated by conventional means such as filtration. If desired, the isolated salt can be converted to p-fluoroaniline by reaction with a base.
