42、量为 60%、间硝基甲苯的含量为 4%，纯品具有低毒、代用品少的特点，广泛用于染料、颜料、塑料、医药、纤维以及助剂中间体等有机合成工业；近年伴随着国际、国内化学工业的不断发展，三种异构体的市场需求量增长强劲。甲苯硝化反应是有机合成中一类重要的反应，一硝基甲苯主要用于生产对甲苯胺，3-氯-4-硝基甲苯，二硝基甲苯等，也用作染料中间体及农药，医药，塑料和合成纤维助剂的中间体。近年来，硝基甲苯的下游用途不断地被进一步开发，其应用前景十分被看好，导致国际市场硝基甲苯的供应日益紧张。二、 国内外发展现状目前我国一硝基甲苯的产量足以左右欧洲市场行情，导致了欧洲一些中间体生产企业日渐萎缩和停产，中间体生产重

43、心逐渐向亚洲转移，使我国的开发，生产销售出现了良好的机遇。国内一硝基甲苯的主要生产企业有：江苏淮河化工有限公司（国营 9395 厂） ，国营375厂，四川红光化工厂(国营565厂)、湖北东方化工厂(国营525厂)、吉化公司染料厂、湘潭有机化工厂、广东茂名有机化工厂等，总生产能力超过20万吨。一硝基甲苯作为医药、农药、染料、香料的中间体，应用广泛。在国际市场上，我国一硝基甲苯及其衍生物的价格比欧洲同类产品平均低30，具有极强的竞争力。目前，我国一硝基甲苯及其衍生物产品的产量，足以左右欧洲市场行情，也导致了欧洲一些历史悠久的中间体生产企业日趋萎缩。据统计，近10年中，西欧被迫关闭 living s
