Is it fesible to separate two liquids boiling points less than 5 degrees?
Yes. It’s the principle on which fractional distillation works. As you heat the mixture, it will first start to boil at the lower of the two liquids boiling points, and that liquid will boil off while the temperature of the mixture will remain constant. After the first liquid is boiled off, the temperature of the remaining fluid will then start to rise till it reaches it’s boiling point. The second liquid will then start to boil.
