草甘膦的合成工艺与检验

南通职业大学毕业设计（论文）草甘膦合成工艺与检验AbstractIn this paper,the synthetic methods and inspection methods of glyphosate werestudied.There are two methods for the synthesis of glyphosate in China,which arerespectively the two methods:the amino acid (IDA)route and the two alkyl phosphoricacid.Domestic more is the preparation of glyphosate by glycine method.And inspection of glyphosate is a lot,such as gas chromatography,spectrophotometry,liquid phase chromatography Ultraviolet Detector method in glyphosate soluble in watercan be in acidic medium with sodium nitrite generation compound,and the compound at342nm have maximum absorption peak,through the quantitative determination ofabsorbanceKey words:glyphosate synthesis test
