Abstract

1305486 Sodium nitrilotriacetate STAUFFER CHEMICAL CO 17 Sept 1970 [15 Oct 1969] 44425/70 Heading C2C Sodium nitrilotriacetate is prepared by continuously reacting an aqueous solution of nitrilotriacetonitrile with an aqueous solution of sodium hydroxide provided in a stoichiometric excess of up to 3%, maintaining the reaction at 95-100‹ C., the period of contact of the reactants not exceeding twenty minutes, and continuously removing ammonia formed during the reaction from the reaction mixture.
