Abstract: What is proposed is a process for preparing a crystalline L-MGDA tri-alkali metal salt by crystallization from an aqueous solution thereof which has been obtained by Strecker synthesis proceeding from L-a-alanine, by reaction with formaldehyde and hydrogen cyanide to give L-a-alanine-N,N-diacetonitrile and subsequent alkaline hydrolysis of the L-a-alanine-N,N-diacetonitrile to give the L-MGDA tri-alkali metal salt, which is characterized in that a temperature of 150°C is not exceeded in the course of alkaline hydrolysis.
Abstract translation: 一种方法，提出了一种用于通过从结晶通过Strecker合成获得的它们的水溶液，来自La丙氨酸开始产生结晶L- MGDA- Trialkalimetallsalzes，通过与甲醛和氢氰酸的La丙氨酸N，N- diacetonitrile和反应 得到的La丙氨酸N，N- Diacetonitrils随后碱性水解为L-MGDA Trialkalimetallsalz，其特征在于，对于在150℃的温度下的碱性水解，不被超过。
