Abstract: 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 of 2-8; b) a separation of the mixture on a selective nonofiltration membrane is performed, a retentate which is richer in N-phosphonomehtylglycine and poorer in halides and a permeate which is richer in halides and poorer in N-phophonomethylglycine being obtained; and c) the N-phosphonomethylglycine is recovered from the retentate.

Abstract: Composition (A) contains at least one alkoxylated 6-18C alkanol (I). Composition (A) contains at least one alkoxylated 6-18C alkanol of formula RO-(A)n-(B)m-H (I). R = 6-18C linear or branched alkyl; A = propyleneoxy (PO); B = ethyleneoxy (EO) or a mixture of EO and PO; n = integer or fractional number of 0-5; and m = integer or fractional number of 0-20. When R is C5H11CH(C3H7)CH2-, n is less than 1, provided that R is a mixture where 70-99 %, by weight of C5H11 is linear and 1-30 %, by weight is EtCH(Me)CH2 and/or MeCH(Me)CH-2CH2. An Independent claim is also included for a method for preparing (I) by reacting ROH with propylene and ethylene oxides.

Abstract: A process for the preparation of N-phosphonomethylglycine, wherein a hexahydrotriazine derivative of the formula (II), wherein X is CN, COOZ, CONR1R2 or CH2OY, is reacted with a triacyl phosphite of the formula P(OCOR3)3 in which the radicals R3 are C1-C18 alkyl, or optionally substituted aryl and the product is hydrolysed and, if X is CH2OY, oxidized.

Abstract: The invention relates to a method for producing N-phosphonomethylglycine fro m an aqueous mixture containing N-phosphonomethylglycine, ammonium halogenides and alkali halides or earth alkali halides and optionally, organic impuritie s in a dissolved form. According to the invention, (a) the pH-value of the mixture is regulated to a value of 2 - 8, (b) the mixture is separated by means of a selective nano-filtration membrane, to obtain a retentate rich in N- phosphonomethylglycine and poor in halogenides and a permeate rich in halogenides and poor in N-phosphonomethylglycine and (c) the N- phosphonmethylglycine is prepared from the retentate. The inventive method enables the production of N-phosphonomethylglycine by simultaneously separating the halogenide salts thereof.
