摘要
介绍了除草剂苯磺隆的性质、国内应用现状和合成方法。以双氰胺钠和糖精为起始原料,经过开环、光气化、缩合等一系列反应制备了苯磺隆,合成反应的总收率可达57.0%以上,纯度可达95.6%以上。此合成工艺已经完成了工业化应用。
The properties, domestic application situation and synthesis method of the herbicide tribenuron-methyl are introduced. Using sodium dicyandiamide and saccharin as raw materials, tribenuron-methyl is synthesized via ring-opening reaction, phosgenation and condensation with total yield of 57.0% and product purity of 95.6%. This synthetic method has been industrialized practically.
