| titleOfInvention | PROCESS FOR THE PRODUCTION OF DI AND POLYAMINES OF DIFENILMETHANE SERIES. |
| abstract | Process for the production of di- and poly (diamino diphenyl methane) comprising the steps of (a) reacting aniline and formaldehyde in the presence of an acid catalyst to produce a reaction mixture containing di- and polyamines; (b) neutralize the reaction mixture containing di- and polyamines; (c) separating the neutralized reaction mixture into an organic phase containing di- and polyamines and an aqueous phase; (d) further treating the organic phase separated in step (c) by (d1) washing with water followed by (d2) separation of the washed mixture into an organic phase and an aqueous phase and (d3) additional fractionation of the organic phase to produce purified di- and polyamines on the one hand and aniline / water on the other; (e) further treating the aqueous phase separated in case (c) by (e1) washing with aniline followed by (e2) separating the washed mixture into an aqueous phase and an organic phase and (e3) further treatment of the aqueous phase to remove the aniline thus leaving an effluent flow where the separation of the phase in step (c) and / or step (e2) is facilitated using either of the methods either alone or in combination of one or more of the other methods: (A) removing some of the water from the neutralized reaction mixture obtained in step (b) or the aqueous phase separated in step (c); (B) adding the inorganic salt to the neutralized reaction mixture obtained in step (b) or the aqueous phase separated in step (c); (C) return some of the aqueous phase obtained in step (e2) or (e3) to the neutralized reaction mixture obtained in step (b) or to the mixture washed in step (e1). |
