Simple and fractional distillation
First, what you might see again is a slight increase at the beginning when you're just heating up your flask. If you were to distill this compound again, the next time you might get something that looks kind of like this orange line.

You'll see this temperature register in the thermometer, and then it'll condense back down into the liquid phase since this side is so cool, and there you'll be collecting these two drops of hexane. You have this toluene now at degrees, again hitting a plateau, because once more that represents a phase change going from liquid to gas, then condensing back into liquid again and dripping into this new receiving flask. Fractional distillation addresses this dilemma -- improving on simple distillation by achieving higher degrees of separation in only one distillation procedure. This is a process which is used to separate out components with boiling points that are very close to each other. Distillation is a process which separates the components of a mixture with different boiling points, through application of heat. Two primary types of distillation processes are fractional and simple distillation. As you can see, ethanol and water, their boiling points aren't too different from each other, only 22 degrees Celsius. Purification of water through distillation is an example. To produce strong drinks, this is the kind of distillation they might need to do. So, simple or fractional? New feed is always being added to the distillation column and products are always being removed. This distills the vapor along the length of the column, and eventually the vapor is composed solely of the more volatile component or an azeotrope. In this way, the two components can be isolated and their respective boiling points recorded for purposes of identification.
It is generally used in the separation of volatile components of the mixture from the other non-volatile components with higher boiling points. What happens if instead you have a three-component mixture?
This is known as continuous, steady-state fractional distillation. When enough energy is added to the boiling flask, the high boiling point component will boil, ascend the column as a gas, and condense as a second fraction.
The distillation towers have liquid outlets at intervals up the column which allow for the withdrawal of different fractions or products having different boiling points or boiling ranges.
By turning the cow or pig, the distillates can be channeled into any chosen receiver.
