摘　　要：双甘膦氧化是合成草甘膦的关键步骤。在200 m L的智能反应釜中通过一系列实验测定了不同温度、压强下双甘膦和草甘膦浓度随时间变化的规律,考察了反应时间、反应压力、反应温度等对双甘膦催化氧化反应的影响。结果表明,草甘膦的收率随着时间呈现先升高后降低的情况,随着压力的增大出现先升高后较小的情况,随着反应温度的增大,草甘膦的收率反而减小。The oxidation of PMIDA was a key step in the glyphosate in the production process. A series of experiments were carried out in a 200 mL reactor to determine the reaction rates with different temperatures and pressures. In influence of reaction time, reaction pressure, reaction temperature on the oxidation of PMIDA were studied. The results showed that the yield of PMG increased at first and then it reduced with the growth of reaction time, reaction pressure and reaction temperature.
