1.title : 분별증류(Fraction Distillation )
2. Theory : Liquid separation by fractional distillation is based on truth that there are more components than original liquid to vaporized stream when liquid mixture is vaporized partially. Boiling point that the stream is pure finally if evaporate again partially after condense new stream becomes vapor of low ingredient. Distillation that this method is simple by fabrication of once can have effect that like do several times apart.
- Fractional distillation pipe
Because most of stream that stand vertically on flask that mixture to separate is filled and comes here are condensed, become to come back by flask. This pipe does stream that also rise and role that widen contact area between liquid that come back. In surface between stream and liquid Some of stream emits heat and condensation. Some liquid is Evaporation by the heat. That these process is continued while stream passes pipe and ingredient that volatility is big in top of pipe
