| titleOfInvention | Diaminoalkyldiphenyl ethers, a process for their preparation and their use |
| abstract | New diaminoalkyldiphenyl ethers of the formula ##STR1## wherein R 1 and R 2 are identical or different and denote hydrogen or methyl, but R 1 and R 2 do not simultaneously represent methyl, n are prepared by a process wherein alkyldiphenyl ethers of the formula ##STR2## wherein R 1 and R 2 have the above-mentioned meaning are acetylated, the diacetyl compounds obtained, in aqueous-alcoholic solution or suspension, are converted to the corresponding dioximes with hydroxylamine, the dried dioximes are subjected to a Beckmann rearrangement and thereafter the diacetylaminoalkyldiphenyl ethers formed are hydrolyzed by means of aqueous mineral acids or alkali metal hydroxide solutions to give the diamines. n The new diaminoalkyldiphenyl ethers are used in the preparation of dyestuffs and polyurethanes and serve as monomers for the preparation of polymers. |
