Abstract

본 발명은 C1∼C4의 알킬기로 이루어 지는 알칸올액중에서 NH3및 파라포름알데 히드의 반응에 의하여 이미노-디메탄올을 생성시킨후, 3차 염기의 존재하에 사용한 알칸올의 비점이하, 바람직하기는 50"C이하의 온도에서 트리알킬(또는 아릴) 포스파이트와 반응시키고, 뒤이어 별도로 C1∼C4의 알킬기로 이루어지는 알칸올에 용해시킨 모노클로로아세트산과 50℃이하의 온도에서 교반 반응시킨후, 무기산으로 처리, 가열하여 탈알킬(또는 아릴)하고. 더욱 가성알칼리로 처리하여 백색 결정의 N-포스포노메틸글리신을 얻는 H-포스포노메틸글리신의 합성방법에 관한 것이다.In the present invention, imino-dimethanol is produced by reaction of NH 3 and paraformaldehyde in an alkanol solution composed of C 1 to C 4 alkyl groups, and then the boiling point of the alkanol used in the presence of a tertiary base, Preferably it is reacted with trialkyl (or aryl) phosphite at a temperature of 50 " C or less, followed by monochloroacetic acid dissolved in an alkanol composed of C 1 -C 4 alkyl groups separately and stirred at a temperature of 50 캜 or lower. The present invention relates to a method for synthesizing H-phosphonomethylglycine, which is treated with an inorganic acid, heated to dealkyl (or aryl), and further treated with caustic alkali to obtain N-phosphonomethylglycine as white crystals.
