The Comprehensive Utilization of Waste Water Derived from the Glyphosate Production

Abstract:

The glyphosate solution, sodium chloride and phosphate solid are separated concurrently by using different mixed solvent extraction processing from glyphosate production wastewater. Among them, ethanol-acetone is the best solvent extraction agent. In glyphosate solution after treatment, glyphosate content is 6.14 %, meanwhile, the content of sodium chloride and phosphate is rather low. So, it can be used as glyphosate agent production. The content of sodium chloride is up to 98 % after recrystallization, which can be as the raw material of chlor-alkai production. When the mother liquor of recrystallization combined with the original wastewater, the glyphosate can be close to the maximum recovery.
