吡啶是目前杂环化合物中开发应用范围最广的品种之一,作为一种重要的精细化工原料,主要应用于农药、医药、饲料添加剂等领域,含吡啶环结构的化合物已成为新型农药的创制方向。近年来随着我国吡啶工业化合成技术的突破,截至2014年底我国吡啶生产能力已达到4.7万t/a左右,逐渐摆脱了依靠进口的局面,市场价格开始大幅度下滑,国内市场价格由2007年的6万元/t下降到目前的3万元/t,原料的本地化供应和价格走低为生产企业积极开发下游产品创造了良好的条件,其
Pyridine is one of the most widely used varieties of heterocyclic compounds. As an important fine chemical raw material, pyridine is mainly used in the fields of pesticides, pharmaceuticals and feed additives. Pyridine ring structure compounds have become the creation of new pesticides direction. In recent years, with the breakthrough of industrial synthesis of pyridine in our country, as of the end of 2014, the production capacity of pyridine in our country has reached 47,000 t / a, gradually getting rid of the situation of relying on imports and the market prices have started to drop sharply. The domestic market prices have dropped from 2007 60,000 yuan / t down to the current 30,000 yuan / t, the localization of raw materials and lower prices for the production of enterprises to actively develop downstream products to create a good condition, its
