摘　　要：研究了低压条件下,以活性炭为催化剂,采用氧气氧化双甘膦制备草甘膦的工艺条件。结果表明:在压力0.2MPa、温度80℃、时间100min、双甘膦质量分数15%时,草甘膦的收率可达96%。Glyphosate Synthesis from N-phosphonomethyliminodiacetic acid（PMIDA） by oxidazing of oxygen along with the catallysis of activated carbon under the low pressure is studied. The results of the experiment show that when presure is 0.2 MPa, temperature is 80℃, time is 100 rain and the concetration of PMIDA is 15%, the yield of glyphosate can be up to 96%.
