Abstract

Procedeu de obtinere a clorhidratatului acidului iminodiacetic, în care se supune reactiei acidul monocloracetic cu acidul aminoacetic în prezenta de hidroxid de calciu drept agent complexant, dupa care amestecul de reactie se aciduleaza cu acid clorhidric apos concentrat la 80 degree C, pH-ul amestecului în timpul adaugarii acidului aminoacetic este mai mare decît 10.The process for obtaining the iminodiacetic acid hydrochloride in which the monocloracetic acid is reacted with the aminoacetic acid in the presence of calcium hydroxide as a complexing agent, after which the reaction mixture is acidified with concentrated aqueous hydrochloric acid at 80 ° C, the pH of the mixture in during the addition of aminoacetic acid is greater than 10.
