国内外DL-蛋氨酸生产现状及市场分析

我国是世界第二大饲料生产国，并以年均8％的速度增长，预计到2010年我国作为饲料添加剂的蛋氨酸需求量将由2002年的50kt／a上升至65kt／a。蛋氨酸是我国目前尚不能生产需大量从国外进口的少数几个精细化工产品之一。分析了国内外蛋氨酸的生产现状及市场情况，对制约我国蛋氨酸发展的重要因素进行了讨论，建议重点发展羟基蛋氨酸及其钙盐产品，并形成以丙烯醛为平台的精细化工产业链。

The Production Situation of D, L-methionine in the world and its Market Analysis

China is the second largest feed production country, and the output of it increases at a rate of 8%. The demand for D,L-methionine as feed additive in China is predicted to increase from 50kt/a in 2002 to 65kt/a in 2010. However, D,L-methionine is one of the few fine chemical products that China isn't able to produce and need to import from foreign countries in large quantities. This paper analyzed the production situation of D,L- methionine and its market situation both at home and abroad, discussed the major factors that restrict the development of D,L-methionine in China, proposed to develop empathetically hydroxymethionine and its calcium salt products, and form a fine chemical industrial chain with acraldehyde as platform.
