| titleOfInvention | Separation process for para-fluoro-aniline |
| abstract | The invention provides a process for separating a para-fluoro aniline from a corresponding para-unsubstituted aniline characterised by dissolving a starting mixture of a para-fluoro aniline of general formula In wherein one of R 1 , R 2 , R 3 and R 4 is a hydrogen atom, a halogen atom, a C 1-3 alkyl group or a CF 3 group, the others being independently selected from hydrogen atoms, halogen atoms and C 1-3 alkyl groups, and R 5 and R 6 are selected from hydrogen and alkyl groups, and a corresponding para-unsubstituted aniline of general formula IIn wherein R 1 , R 2 , R 3 , R 4 , R 5 and R 6 are the same as in formula I in an aqueous solution of a non-oxidising acid, and cooling the solution to allow a mixture of salts of the anilines of formulae I and II having a highest mol percentage of the aniline of formula I than in the starting mixture to crystallise out. |
