Also, kciray:, I'd like to remind you of the Forum Rules{click}  Whether its for a high school class,or just your knowledge, or something you're puttering about in a basement lab, we want you to learn to help yourself solve most problems.

Also, please realize, whether you "need" or "want" absolute ethanol, or need to learn how for the fun of it or some application, that the production of absolute ethanol, even in tiny amounts, is tantamount to bootlegging, which is illegal, in just about any jurisdiction that has laws.

I've already bought CaCl₂

You can use stoichiometry, if you'd like to try.  What is the reaction that is supposed to happen?  Can you convert that into numbers you can use?

CaCl₂ is soluble in ethanol. Moreover, Anhydrous CaCl₂ forms solvate with ethanol (CaCl₂·3C₂H₅OH). Lowitz around 1800 obtained small amount of absolute ethanol by this dehydrating agent. Using this method you do not dehydrate ethanol completely and you need repetead use a good distillation column.
In lab CaO, CaC₂ or azeotropic destillation with benzene are used.
