吡啶系列原料国内市场分析

Market Analysis of Pyridine Series Raw Materials in China

吡啶的生产方法有两种:一是从煤焦油中提取;二是从氨和甲醛、乙醛的合成过程中获得。我国一直采用前者生产,产量为200-300t/a,市场需求主要依靠进口,进口量最大的是比利时Reilly公司,1999年为2000多吨,占全国总消耗量的45％。2000年底,该公司与中国南通醋酸化工厂合作建立了1.1万t/a的吡啶系列产品生产厂,其中纯吡啶生产能力8000t/a、甲基吡啶3000t/a,填补了国内合成吡啶的空白。随着国内应用技术的发展,现已有多种用吡啶原料生产的产品打入国际市场。

There are two manufacturing methods of pyridine: extraction from coal tar and synthesis of ammonia, formaldehyde and acetaldehyde. China has been adopting the first method with an output of 200 ~300t/a, and market demand mainly depends on imports. Belgium Reilly is the biggest exporter which exported over 2000 tons of pyridine to China in 1999, making up 45% of China's total consumption. At the end of 2000, Reilly cooperated with China Nantong Acetic Acid Chemical Plant to build a pyridine plant with a capacity of 11000t/a, in which pure pyridine capacity is 8000t/a, and 3000t/a is methyl pyridine. The plant filled up a domestic blank of synthetic pyridine. With the development of application technology in China, many products based on pyridine have entered the international market.
