New Glyphosate Production Technology      

Zhejiang Jingma Chemicals Co., Ltd. and Zhejiang University have jointly developed a glyphosate production technology using the air oxidation process. The technology has already passed technical appraisal. Jingma Chemicals Co., Ltd. is engaged in the export of herbicides such as glyphosate. The production capacity of glyphosate in the company is 10 000 t/a. The glyphosate production in the company used hydrogen peroxide for oxidation in the past, and the production process not only had hazards of combustion and explosion but also generated great quantities of waste acids and waste gases.
   The new process is innovative in air oxidation and membrane separation. It has the features of high reaction yield, low production cost, comprehensive resource utilization, energy conservation and little pollutant discharge. The product purity can reach over 97%, being around 2.0 percentage points higher than that in the traditional process.
