Homebrew PCBs

I remember molecular sieves ,but would they get all the water ? what was nice about them you could bake them and reuse them

Distillation of ethanol will only produce about 95% ethanol. The mixture of ethanol and water produce what is known as an azeotrope. Azeotropes are a mixture of at least two different liquids. Their mixture can either have a higher boiling point than either of the components or they can have a lower boiling point. Azeotropes occur when fraction of the liquids cannot be altered by distillation.

Here's an interesting youtube video explaining this. How to make 100% Ethanol (anhydrous) <https://www.youtube.com/watch?v=ratR1ngcWss>

in this video we will be making some 100% Ethanol from 95% Ethanol. I use molecular sieves but other drying agents can be used. I just like sieves the most....
