Abstract

Process for the production of alkaline salts of aminopolycarboxylic acids by reaction of the corresponding nitriles of the carboxylic acid with aqueous alkali at high temperature, characterized in that a suspension of the nitrile of aminopolycarboxylic acid is obtained in an aqueous solution of at least 30%. % by weight of alkaline hydroxide which, at least, contains stoichiometric quantities of alkali hydroxide, this suspension is placed in a reaction vessel which is maintained at a temperature of 60 to 150ºC and by intensive agitation and, if necessary, using pressure, the salt formation is started and the salt is continued, regulating in such a way the speed of transport of the suspension in the reaction vessel, that the mixture, which reacts strongly and swells, does not rise above the zone of a perfect intermixed and that the ammonia that forms during the reaction, as well as the existing water in the container, are evacuated in a continuous manner, essentially by the heat of the reaction but, in any case, in such form of the said container, that during the development of the reaction always penetrate water or steam through the entire mixture of reaction until the product of the reaction evaporates until it is approximately dry.
