吡啶类化合物是农药生产中十分重要的原料和中间体,其中的一甲基吡啶是吡啶类化合物中的重要品种。一甲基吡啶主要为3-甲基吡啶,此外还有2-甲基吡啶和4-甲基吡啶。在以丙烯醛和氨为原料合成3-甲基吡啶中,有40%～50%为3-甲基吡啶,还有5%左右的2-甲基吡啶和8%左右的4-甲基吡啶。以一甲基吡啶为原料开发的农药品种中,尤以3-甲基吡啶的最多。以下分别对2-甲基吡啶、3-甲基吡啶
Pyridine compounds are very important raw materials and intermediates in the production of pesticides, of which picoline is an important variety of pyridine compounds. Monomethyl pyridine is mainly 3-picoline, in addition to 2-picoline and 4-picoline. In the acrolein and ammonia as raw materials to the synthesis of 3-methyl pyridine, 40% to 50% of 3-methyl pyridine, there are about 5% of 2-methyl pyridine and 8% of 4-methyl pyridine . Of methylpyridine as raw materials developed pesticide varieties, especially 3-methyl pyridine up. The following were 2-picoline, 3-picoline
