吡啶系列原料是化学工业的重要原料,广泛应用于医药、农药、饲料及一些精细化工产品的生产中。进入九十年代后我国对吡啶系列产品数量和品种的需求加大,从过去的两三个品种发展到近十个,年需求量也从1000多吨发展到4500～5000吨左右,更可喜的是一些化工厂逐步利用吡啶系列原料 Pyridine series raw materials are important raw materials for the chemical industry and are widely used in the production of pharmaceuticals, pesticides, feedstuffs and some fine chemical products. After entering the 1990s, China’s demand for the number and variety of pyridine series products has increased. From the past two or three varieties to nearly ten, the annual demand has also grown from more than 1,000 tons to about 4500 to 5,000 tons, which is even more gratifying. Some chemical plants gradually use pyridine series raw materials
