Methf water azeotrope
WebEen bekende azeotroop is een mengsel van 97 vol-% ethanol en 3 vol-% water (95.5% bij massa). Een azeotroop heeft, als consequentie van de wetten van de thermodynamica, altijd een kookpunt dat óf hoger is dan het hoogste van de twee kookpunten van de componenten, óf lager is dan het laagste van de twee kookpunten van de componenten. Web1 sep. 2016 · Pressure-swing distillation is one such technique for ethanol separation. It can be observed from Fig. 1 that the mixture of ethanol and water shows significant change from 0.885 to 0.812 in azeotropic composition on changing pressure, making it suitable for pressure swing distillation.
