| titleOfInvention | Manufacture of highly chlorinated hydro-aromatic products containing nitrogen |
| abstract | Highly chlorinated hydroaromatic products containing nitrogen are prepared by chlorinating hydrochlorides of aromatic amines with gaseous chlorine in an indifferent liquid, moisture being excluded. Thus aniline hydrochloride, chlorinated first in cold and then in hot chlorobenzene, yields an octochlor-chlorketimido-hexahydrobenzene, and in benzene, if chlorination is stopped when dissolution has occurred, chiefly a hexachlor-chlorketimidohexahydrobenzene: a - and b -naphthylamines yield pentachlor-chlorketimido-tetrahydronaphthalenes; with b -naphthylamine the reaction is complete in cold benzene suspension but with a -naphthylamine a hot chlorbenzene suspension is necessary: a - and b -aminoanthraquinones similarly yield pentachlor-a - or b -chlorketimidotetrahydroanthraquinone when chlorinated in benzene and chlorbenzene respectively. Examples are given of the preparation of the above specified ketimides, the suspensions of the amine hydrochlorides being first prepared by passing gaseous hydrochloric acid into benzene or chlorbenzene solutions of the parent amines. |
