For the purpose of isolating caffeine, i have made some Methyl Trichloride (Chloroform) from the Calcium Hypochlorite/Acetone method. I then distilled
the Methyl Trichloride from the mix of biproducts and obtained what i assume is Methyl Trichloride with a layer of water ontop. Now i can just use a
syringe to draw off the water layer, for the most part. But how would i go about removing the remaining traces of water?
I have done some research and found this site: http://orgchem.colorado.edu/hndbksupport/drying/drying.html
Would i be correct in saying i could use magnesium sulfate (epsom salts) to remove the traces of water? Would there be any adverse reactions with the
Methyl Trichloride and magnesium sulfate? Is this method advisable or would there be a better method? Also, in regards to evaporation rate, what kind
of loss could i expect from processing to remove the water? Also note i have no lab equipment or difficult-to-obtain chemicals, so everything is
improvised.
Any help would be appreciated.

the drying of organic solvents is exhaustively described elsewhere. i'm not trying to be rude, but this is basic knowledge, and you're far better off
educating yourself on this topic and in your case, the toxicological profile of chloroform before you attempt to use it AT ALL.

I'm just asking for some confirmation about a drying method that seems applicable. I just dont want to screw up ~8 hours of work.
Also, because i have 2 posts doesnt mean i'm ignorant to safety precautions.

MgSO4 is ok for CHCl3. and there is always google

Doesn't the trichloromethane thread have info on drying this? It should have a couple posts in one of the four pages.
