全球吡啶类化合物的市场现状及前景分析

Global Market Situation and Prospect Analysis on Pyridines

吡啶及其衍生物作为一种高附加值的精细化工产品,广泛应用于农药、医药、染料、香料、橡胶、饲料以及日用化工等领域。20世纪50年代以前,从煤焦油中分离是吡啶的唯一来源,之后开始了吡啶的化学合成。目前,全球98%以上的吡啶都采用化学法合成。世界上能够掌握吡啶合成技术的公司不多,10年前有美国、日本、德国和瑞士等几家公司;目前又增加了中国台湾、中国大陆和印度等几家公司。随着经济的发展和吡啶产能的增加,全球吡啶化合物的消费结构也发生了较大变化。

World consumption of pyridine was 118 thousand tons and global capacity utilization declined to 66% in 2007. During the period of 2003 to 2007, world capacity of pyridine grew at an average rate annually of 8.7%, exceeding its annual consumption with average rate of 3.5% in the world. During the period of 2003 to year-end of 2007, approximately 45 thousand tons of annual pyridine capacity was added, primarily in China, India and the United States. Most capacity increment was installed in Asia to meet strong demand for paraquat and niacinamide/niacin. Growth in demand for pyridine in the US and Europe is forecasted to be moderate, and significant growth is expected in China.
