[Aims] The analysis method for glyphosate synthesis process was established by on-line reaction infrared analysis system. [Methods] The synthesis process of glyphosate prepared by glycine method was detected by React IR on-line analysis system. The reaction process of glyphosate synthesis steps and the changes in the internal composition of glyphosate synthesis were monitored without sampling. [Results] Glyphosate was prepared by glycine method.Depolymerization, condensation and esterification of the process were all quick reactions, which could reduce reaction time, reduce energy consumption and save cost. [Conclusions] The React IR real-time monitoring of glyphosate synthesis technology provides an effective monitoring and analysis method for the continuous production of glyphosate,which can be used in laboratory and industrial production.
