  • 上游原料:氧 --> 一氧化碳 --> 石蜡 --> 醋酸铜 --> 丙醛 --> 环己基氨基磺酸钠 --> 环烷酸钴 --> 羰基镍 --> 环烷酸锰
  • 所属类别三:饲料添加剂: 饲料贮存添加剂
  • 方法二:其制备方法是以乙烯与一氧化碳、氢气为原料,在环烷酸钴等催化剂存在下,于100~200℃、20~30 MPa条件下在极性溶剂中反应生成丙醛,进一步经空气或氧气氧化,催化剂用环烷酸钴、环烷酸锰、乙酸铜等,反应温度为60℃,常压氧化反应而制得丙酸,丙醛的转化率为95%~98%。反应方程式:CH 2 =CH 2 +CO+H 2 →CH 3 CH 2 CHO 2CH 3 CH 2 CHO+O 2 →2CH 3 CH 2 COOH 该方法是国外生产丙酸的主要方法。
  • 可燃性危险特性:遇明火、高温、强氧化剂可燃; 燃烧排放刺激烟雾
  • 用途五:丙酸是重要的化工原料,是杀菌剂甲霜灵、苯霜灵,除草剂敌稗、喹禾灵、嗯唑禾草灵、吡氟禾草灵、噻唑禾草灵、氟吡氯禾灵、乳氟禾草灵、丙草胺、敌草胺等的中间体,也是医药中间体,并可作为食品工业防腐剂、青饲料的保鲜剂等。
  • 外观性质:无色液体,有刺激性气味。
  • 下游产品:丙酸甲酯 --> 甲霜灵 --> 3,4-二氨基喹啉 --> 丙酸乙酯 --> 环丙沙星 --> 4-氨基-3-硝基喹啉 --> DL-丙氨酸 --> 富马酸二甲酯 --> 5-羧基-异二氢吲哚 --> 丙酸钠 --> 2-溴乙酸乙酯 --> 4-氯-3-硝基喹啉 --> 异二氢吲哚-5-甲酸甲酯 --> 3-苯基环氧乙烷甲酸乙酯 --> 2-溴蒽 --> 3-氯丙酸 --> 敌稗 --> 5-溴异二氢吲哚 --> 2-甲基己酸 --> 4-溴异二氢吲哚 --> 3-甲基喹啉 --> 2-氯丙酸 --> 硫普罗宁 --> 6-溴-1,2,3,4-四氢-2-喹啉酮 --> 敌草胺 --> 2-氯丙酸乙酯 --> 6-氨基-2-(2,4-二甲苯基)-1H-苯并[DE]异喹啉-1,3(2H)-二酮 --> 2-溴丙酸 --> 2-氯丙酰
  • 用途六:丙酸是重要的精细化学品,也是其他许多精细化学品的中间体。主要用作食品和饲料添加剂,其次用于家药珍重草剂及医药、香料等。在谷物和饲料添加剂方面,丙酸的应用效果显著,消费量增长很快。(1)食口添加剂。丙酸钙和丙酸钠能防止由于微生物作用而引起的食物腐败变质,延长食品保存时间,行之有效用于面包和糕点的保存。(2)谷物保存剂。丙酸用于谷物的防霉烂和防结块获得成功,为谷物的长期贮藏保鲜提供了新方法。(3)饮料保藏剂。试验证明,丙酸、丙酸钠、丙酸钙都是较好的饲料保藏剂,多用于保藏猪、牛、羊和家禽用饲料,其中以丙酸钙效果最好。丙酸盐类中的丙酸锌和丙酸镉是生产对苯二甲酸酯的聚酯用催化剂;丙酸酯类品种很多,具有各自的用
