Abstract: The invention relates to a method for fractionation of water soluble or dispersible synthetic polymers containing amino groups with a broad molar ma ss distribution by means of ultrafiltration. The polymer solution or dispersion which is to be fractionated is continuously fed into an utltrafiltration circuit comprising at least one ultrafiltration unit and the retentate with a narrower molar mass distribution and the permeate are continuously discharge d in such a way that the ultrafiltration circuit is placed in a substantially stationary state. The invention also relates to polymers which can be obtain ed according to the inventive method and to the use thereof.

Abstract: The present invention relates to a process for the recovery of N-phosphonomethylglycine from an aqueous mixture which contains N-phosphonomethylglycine, ammonium halides, and alkali metal or alkaline earth metal halides and optionally organic impurities in dissolved form, where (a) the pH of the mixture is adjusted to a value in the range from 2 to 8, (b) a separation of the mixture on a selective nanofiltration membrane is performed, a retentate which is richer in N-phosphonomethylglycine and poorer in halides and a permeate which is richer in halides and poorer in N-phosphonomethylglycine being obtained, and (c) the N-phosphonomethylglycine is recovered from the retentate. The process according to the invention makes possible the recovery of the N-phosphonomethylglycine with simultaneous separation of the halide salts.

Abstract: La invencion se refiere a un metodo para producir ajustes de liquidos de colorantes azo basicos a partir de fenilendiamina I, la cual puede ser sustituida por alquilo o alcoxi, por diazoacion y copulacion en solucion acida. De acuerdo con este metodo, la fenilendiamina se diazotiza con nitrito de sodio en presencia de al menos dos acidos organicos que consisten en al menos un primer acido (A) con un valor pKA = 4.0 y al menos un segundo acido (B) con un valor pKA = 4.1, y una vez que se completa la copulacion, se lleva a cabo una nanofiltracion.
