How dry do you want them? 1 ppb water or 5% water? You need to be a tiny bit more specific.

Process for drying ethanol and acetone is written in Vogel's Textbook of Practical Organic Chemistry, 3rd ed. You can find it on Rhodium's page.

It's motherfuckers like you that ruin the hive's spirit. Cluttering up the forums with stupid as shit questions. You're the ignorant one. It's annoying as hell to see the same fucking questions over and over. Get a fucking clue. It's not enough you're a fucking dumbass, asking pathetic questions, but you have an attitude, getting on here telling us our business? Get-FUCKING-lost!
Us? Ignorant? We go out of our way to help stupid ass people like you - BUT FIRST YOU HAVE TO HELP YOURSELF. Nobody responds to stupid fucking questions like yours... it's just a waste of time.

Short simple answer. Dry out epsom salt in oven for about an hour or so on 350f. Put dried epsom in your acetone or whatever you want to dry. Repeat 2 more times. This answer is in the search engine and over at rhodiums. Try doing a little searching before asking questions that have been covered numerous times.

Title: CaCl2 for acetone and CaO for alcohol.

CaCl2 for acetone and CaO for alcohol.  Alcohol (ethanol) is very hydroscopic.  Salts that form hydrates are not good enough for drying alcohol.  You need something that reacts with water like CaO.  Download Vogels from Rhodium's page.

You didn´t specify that you wanted them for recrystallisation. Hence I, had no idea how dry you wanted the solvents. If I had knew I would have answered you dry ethanol by azeotropical distillation with toluene and acetone by simple distillation.

What´s this attitude you´re showing because you didn´t get an answer within 10 minutes after your lazy ass managed to scribble the question? Instead of getting used to be spoonfed all information, why don´t you learn how to fucking find it yourself. Noone here will spoonfeed you anyway.
