    摘要: In a process and an apparatus for the continuous preparation of N-acylamino carboxylic acids and N-acylamino sulfonic acids, and their alkali metal salts, from the alkali metal salts of amino carboxylic acids and amino sulfonic acids, respectively, and carbonyl halides in a reactor designed as circulating circuit, the reactants are fed for immediate reaction into the circulating circuit, and a part of the product solution corresponding to the amount fed in is continuously discharged from the circulating circuit. The reactants are circulated by a circulating pump. The temperature in the reactors is controlled. The heat produced in the reaction is removed.
