补充资料:水蒸气蒸馏
      直接向不混溶于水的液体混合物中通入水蒸气的蒸馏方法,常用来降低操作温度,以便将高沸点或热敏性物质从料液中蒸发出来,从而得到纯化,如脂肪酸、苯胺、松节油的提取和精制。
  
  将水蒸气连续通入含有可挥发物质 A的混合液,在达到相平衡时,汽相含有水蒸气和组分A,汽相的总压等于水蒸气分压和组分 A分压之和。当汽相总压等于外压时,液体便在远低于组分A的正常沸点的温度下沸腾,组分A随水蒸气蒸出。在水蒸气蒸馏操作中,水蒸气起到载热体和降低沸点的作用。原则上,任何与料液不互溶的气体或蒸气皆可使用;但水蒸气价廉易得,冷却后容易分离,故最为常用。如果蒸馏操作中使用饱和水蒸气,且外部加入的热量不足,水蒸气将部分冷凝,形成两个液相。这时汽相中水蒸气的分压最大,等于其饱和蒸气压,液体将在最低温度下沸腾,但由于水的饱和蒸气压远高于组分A的蒸气分压,所以馏出汽相中组分A的含量很少,水蒸气的耗用量最大。为节省能耗,在蒸馏釜内须避免出现水蒸气的冷凝。为此可采用外部加热或使用过热蒸汽将料液升温到允许的最高温度,以增大组分A的蒸气分压。同时选择较低的操作压力,降低水蒸气的分压,节省水蒸气的用量。
