引言 1960年美国俄亥俄标准油公司(Standard oil Co.,ohio)建成了用丙烯为原料,经氨氧化反应合成丙烯腈的工厂(2.2万吨/年)。由于此法具有显著的优越性,因而受到石油化学界的极大重视。其特点是:对原料(丙烯、氨及空气)要求不高;可以大量而且廉价供应;反应不需压力或特殊合金材料;操作安全;产品精制方便及成本低。目前日本已有四个公司用此法性产。此外,美国杜邦公司(Du Pont Co. )也发展了利用氨、丙烯及空气在銀催化剂上合成丙烯腈的方法,并将于今年投入生产(2.2万吨/年)。近几年来,英国 INTRODUCTION In 1960, Standard Oil Co. (ohio) established a plant for the synthesis of acrylonitrile by ammoxidation (22,000 tons / year) using propylene as feedstock. Because of this method has significant superiority, and therefore received great attention by the petrochemical community. Its features are: the raw materials (propylene, ammonia and air) less demanding; can be large and cheap supply; reaction without pressure or special alloy materials; safe operation; product refined convenience and low cost. At present, four Japanese companies have used this method to produce products. In addition, Du Pont Co., the United States, has also developed a method of synthesizing acrylonitrile on silver catalysts using ammonia, propylene and air and will start production this year (22,000 tons / year). In recent years, Britain
