Abstract

PURPOSE: To lower the cyanide concentration in the reaction mixture after the completion of the reaction, in the preparation of an alkali salt of amino-polyacetic acid, by controlling the feeding amount of the raw materials referring the concentration of cyanide in the reaction mixture determined from the potential difference between the cyanide ion electrode and the reference electrode.
