草甘膦是一种广谱灭生性有机磷除草剂,具有良好的传导性能,在农业等方面具有广泛的用途。目前,草甘瞵的工业生产方法主要有甘氨酸法和亚氨基二乙酸(IDA)两种。其中IDA路线是目前最先进的生产工艺,使用该路线生产的草甘膦占总产量的75%以上。这一路线的关键点有两个:一是中间产物IDA的合成,二是双甘膦的氧化。1.中间产物IDA的合成目前,IDA的合成主要用氯乙酸法(已被淘汰)、 Glyphosate is a broad spectrum of extinct organic phosphorus herbicides, has good conductivity, has a wide range of uses in agriculture and so on. At present, there are two main methods of industrial production of Glycyrrhiza glabra: glycine method and iminodiacetic acid (IDA). Among them, IDA route is the most advanced production technology at present, and glyphosate produced by using this route accounts for more than 75% of the total output. There are two key points in this route: one is the synthesis of intermediate product IDA and the other is the oxidation of PMIDA. 1. Synthesis of Intermediate Product IDA At present, the synthesis of IDA is mainly based on the chloroacetic acid method (which has been eliminated)
