Abstract: The present invention relates to a process for the preparation of N-phosphonomethyliminodiacetic acid by reacting an alkali metal salt of iminodiacetic acid with phosphorus trichloride in aqueous solution with formation of the hydrochloride of iminodiacetic acid, phosphorous acid and of the corresponding alkali metal chloride, followed by reaction with a formaldehyde source and, if desired, recovery of the N-phosphonomethyliminodiacetic acid from the reaction mixture, in which water, which may comprise HCl, is removed from the reaction mixture during and/or after reacting the alkali metal salt of iminodiacetic acid with phosphorus trichloride until the concentration of iminodiacetic acid hydrochloride is at least 40% by weight, based on the weight of the reaction mixture minus the weight of alkali metal chloride. The process makes possible the preparation of N-phosphonomethyliminodiacetic acid in a simple fashion and in high yield.

Abstract: A process for the separation of acids from reaction mixtures by means of an auxiliary base (I) is characterized by (a) the base (I) forming a salt with the acid that is liquid at temperatures that do not lead to significant decomposition of the product during separation of the liquid salt (b) the salt of the base (I) forming two non-miscible phases with the product or solution of the product in a suitable solvent.

Abstract: In the process for preparing ionic liquids, an ionic liquid is firstly reacted with an alkoxide or with barium hydroxide and is subsequently neutralized with an acid. The ionic liquid contains a phosphonium and/or ammonium cation and an anion selected from the group consisting of halides, arylsulfonates, alkylsulfonates, sulfate, hydroxysulfate, alkylsulfates, hydrogencarbonate, carbonate. triflate and carboxylates. In this process, virtually any anions can be introduced into the ionic liquids.
