本文以双甘膦为原料催化氧化制备草甘膦，考察了双甘膦浓度、分散剂、反应温度以及搅拌速度等对双甘膦转化率和草甘膦收率的影响。在最佳工艺条件下，双甘膦的转化率可以达到99.3％，草甘膦的收率可以达到87.3％。%In this paper,N-phosphonomethyl iminodiacetic acid was synthesized by catalytic oxidation of glyphosate. The effects of the concentration, dispersing agent, temperature and stirring speed on both the conversion of N -phosphonomethyl iminodiacetic acid and the yield of the glyphosate were investigated. Under appropriate condition,the conversion of N-phosphonomethyl iminodiacetic acid is 99. 3%,the yield of the glyphosate is over 87. 3%.
