Process for the preparation of bis(aminophenyl)alkanes |
| abstract |
An improved process is described for the preparation of bis(aminophenyl)alkanes which comprises heating the corresponding bis(di-alkoxyphenyl)alkane or corresponding cyclic ethers of bis(phenyl)alkanes with an at least stoichiometric proportion of an aniline acid addition salt, optionally in the presence of an inert organic solvent. |
