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。

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
稍有刺鼻的恶臭气味。能与水混溶，溶于乙醇、氯仿和乙醚。易燃。低毒，半数致死量（大鼠，经口）4.29g/kg。有腐蚀性。爆炸极限2.1%-12%。
用途四:防腐剂；防霉剂；香料。用于啤酒等的粘性物质抑阻剂。
蒸气压:2.4 mm Hg ( 20 °C)
含量分析:取试样3g(准确至0.1mg)，放入250ml烧瓶中，加水50ml，混合。加酚酞试液(TS-167)数滴，用lmol/L氢氧化钠滴定至最初出现微红色并维持30s以上。每毫升lmol/L氢氧化钠相当于丙酸(C3H6O2)74.08mg。
