摘　　要：研究了双甘膦浓硫酸氧化法制草甘膦水剂,考察了物料比、反应温度及反应时间等对双甘膦氧化的影响。得出物料比、反就温度及反应时间对双甘膦氧化都有很大影响。以双甘膦∶浓硫酸=1∶2.5(重量比),反应温度为105～115℃,反应时间控制在3h的条件下双甘膦转化率为90%The paper researched of oxidizing pmida to produce glyphosate aqueos solution with oxidizer that was sulfuric acid. In the experiment, a test with react substance proportion and temperature, which affected greatly pmida oridized was done. the condition controlled pmida oridzed, pmida：sulfuri acid =1 ： 2.5（weight rate）, reaction temperature at 105-115℃ and reaction time on 3 h, thc rate that pmida was made into glyphosate reached 90 %.
