There is disclosed a process for producing the alkali metal salts of N-phosphonomethylglycine which comprises heating to an elevated temperature an aqueous solution of a di- or tri-alkali metal salt of N-alkyl-N-phosphonomethylglycine. The N-alkyl substituent contains at least one hydrogen on the beta carbon atom.
本发明公开了一种生产N-膦酰甲基甘氨酸碱金属盐的工艺,该工艺包括将N-烷基-N-膦酰甲基甘氨酸的二碱金属盐或三碱金属盐的水溶液加热至高温。N- 烷基取代基在 beta 碳原子上至少含有一个氢。
