clonazepam is a benzo, benzo stands for benzodiazepanes.
i made a mistake on my post, you CAN make chloral hydrate yourself, by bubbling chlorine gas through anhydrous alcohol.
heres a website i found:
Procedure
Put 350ml of anhydrous alcohol (Dry or distill pure grain alcohol.) into a 600ml flask and put a 2-hole stopper into the top.
Put 2" of bleach and 1 tsp. 'Sani-flush' into a clean 500ml flask and put a 2-hole stopper into the top.
Attach a fish tank aerator to the flask in step 2 by a lenght of plastic tubing and inserting this tubing into the top of the stopper.
Connect the remaining opening of the flask in step 2 to one of the openings on the flask in step 1 using another piece of plastic tubing.
Place a piece of glass tubing long enough to reach the bottom of the flask in step 1 and insert it into the tubing in step 4 so that it reaches into the bottom of the alcohol flask. (This should start the bubbling of chlorine gas through the alcohol.)
Place another piece of plastic tubing into the remaining opening of the alcohol flask and put the open end into the bottom of a 500ml flask.
Place the 500ml flask in step 6 in a cold water bath.
Continue to bubble the chlorine gas through the alcohol until it will absorb no more gas.
Gently heat the alcohol flask using a water bath until the alcohol begins to boil. (Some of the alcohol will distill off into the flask in step 6, several times during the chlorinating process pour the alcohol that distills back into the alcohol flask into the alcohol flask.)
When the flask is totally chlorinated it is poured into a pyrex dish and allowed to cool. (If the above steps were done properly you should have a large mass of crystals upon cooling.)
Pour concentrated sulfuric acid equal to 3 times the volume of the impure Chloral Hydrate (the crystal mass) into the dish.
Heat this dish on a water bath until the Chloral Hydrate crystals are melted, this soultion should then be stirred for approx. 3 min.
Pour the solution from step 12 back into a clean dry 1000ml flask and heat (Do not heat above 200F.)
As the solution in step 13 heats up the still impure Chloral Hydrate will begin to float to the surface, when it stops rising use a basting syringe (Or whatever you prefer.) to draw off the floating layer of Chloral and place this into a clean, dry beaker.
Repeat step 14 until no more Chloral rises to the surface.
Heat the beaker in the above step 14 to around 190F for 20 min. to get rid of any alcohol or acid remaining in this solution.
Pour the solution from step 16 back into the flask in step 13 (1000ml flask) and add an equal amount (by volume) of sulfuric acid to this flask and stir for approx. 5 min.
Distill off the Chloral Hydrate (which distills at 210F) into a clean dry beaker that is placed in an ice bath. (This should not be hard as the sulfuric acid distills at 722F.)
Place the distilled Chloral from the above step back into a cleaned, dry 500ml flask and add an equal amount (by volume) of calcium oxide to this flask.
Once again distill off the Chloral until the surface of the calcium oxide is dry.
the saniflush and bleach thing is just so you can find a chlorine source.
