题 目：草甘膦的合成工艺与检验摘 要 本文研究了关于草甘膦的性质合成方式与检验方法。草甘膦的合成方法在国内常用的有两种方法分别为亚氨基二乙酸(IDA)路线和路亚磷酸二烷基脂线。国内较多的则是用甘氨酸法制备草甘膦。 而草甘膦的检验方法有很多，例如气相色谱法、分光光度法、液相色谱紫外检测器法等在草甘膦溶于水后可在酸性介质中与亚硝酸钠生成化合物，而该化合物在 342nm处有最大吸收峰，可以通过测定吸光度定量。关键词：草甘膦 合成 检验 AbstractIn this paper, the synthetic methods and inspection methods of glyphosate were studied.There are two methods for the synthesis of glyphosate in China, which are respectively the two methods: the amino acid (IDA) route and the two alkyl phosphoric acid. 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 water can be in acidic medium with sodium nitrite generation compound, and the compound at 342nm have maximum absorption peak, through the quantitative determination of absorbanceKey words: glyphosate synthesis test 11目 录摘 要...............................................................................................................1Abstract............................................................................................................21 绪论................................................................................................................42 草柑膦的合成................................................................................................42.1 甘氨酸法合成草甘膦 ..............................................................................................42.1.1 不同反应阶段合成液中水分的测定.............................................................42.1.2 脱水剂用量对合成草甘膦的影响.....................................
