  • PROCESS FOR PRODUCTION OF DI- AND POLYAMINES OF THE DIPHENYLMETHANE SERIES
    Publication number: 20100204510
    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) neutralising the reaction mixture containing di- and polyamines; (c) separating the neutralised reaction mixture into an organic phase containing di- and polyamines and an aqueous phase; (d) further treating the organic phase separated off in step (c) by (d1) washing with water followed by (d2) separating the washed mixture into an organic phase and an aqueous phase and (d3) further fractionation of the organic phase to produce purified di- and polyamines on the one hand and aniline/water on the other hand; (e) further treating the aqueous phase separated off in step (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 thereby leaving an efflue

  • Polyols
    Patent number: 5767324
    Abstract: Process for reducing the level of unsaturation in a polyether polyol having an oxypropylene content of at least 30% by weight calculated on the total amount of oxyalkylene units in the polyol and having a number average equivalent weight of at least 1000 by subjecting the polyol to ultrafiltration.
