摘要
20 0 3年 ,我国 2 氯 5 氯甲基吡啶的生产能力为 10 0 0t/a ,产量 6 0 0t左右 ,消费构成为农药 5 0 0t、医药30t、出口 70t。预计 2 0 0 5年我国 2 氯 5 氯甲基吡啶的总消费量将达到 95 0t,2 0 0 3～ 2 0 0 5年的年均增长率为 2 5 83%。在我国 ,2 氯 5 氯甲基吡啶主要用来生产吡虫啉和啶虫脒。
In 2003 the capacity of 2-chloro-5-chloromethylpyridine in China was 1000t/a, with output of 600t and consumption breakdown 500t for pesticide, 30t for pharmaceuticals and 70t for export. The total consumption of 2-chloro-5-chloromethylpyridine in China is forecasted at about 950t in 2005, and the average annual increase rate is estimated at 25.83% during 2003～2005.In China, 2-chloro-5-chloromethylpyridine is mainly used to produce imidacloprid and acetamiprid.
