Chloroform is classified as an extremely hazardous substance in the United States as defined in Section 302 of the U.S. Emergency Planning and Community Right-to-Know Act (42 U.S.C. 11002), and is subject to strict reporting requirements by facilities that produce, store, or use it in significant quantities.
Here is how you can make it at home.
Chloroform, or trichloromethane, is an organic compound with formula CHCl3. It is a colorless, strong-smelling, dense liquid that is produced on a large scale as a precursor to PTFE. It is also a precursor to various refrigerants. It is one of the four chloromethanes and a trihalomethane. It is a powerful anesthetic, euphoriant, anxiolytic and sedative when inhaled or ingested. A rag soaked in Chloroform can put someone under after about 5 minutes of deep exposure, and remain under so long as applied to the nose and mouth (Though there is a high change of them choking on their own tongue).
Chloroform if stored improperly (on purpose or otherwise) degrades over time into Phosgene which was a chemical weapon that was used in World War 1. Phosgene is the organic chemical compound with the formula COCl2. It is a colorless gas; in low concentrations, its odor resembles that of freshly cut hay or grass.
The supplies and ingredients needed to make Chloroform at home are...
Wear PPE! Begin with wearing your gloves and gas mask. This process should be done in a well lit and well ventilated area.
Cool your Bleach. Add some ice into your glassware and add 1/2 liter of bleach or place 1/2 liter of bleach into a freezer. Always cool your bleach as the reaction will cause the mixture to heat up drastically.
Add Acetone. Add 10ml of acetone into the glassware. You want to use the bleach as a 50:1 ratio to acetone or 50 parts Bleach to 1 part Acetone. Stir gently.
This is where the two chemicals react with each other. It is not instant. Leave it alone for about 60 minutes. It will take about that time for the reaction to fully process. You will later notice a white cloud of vapor coming from the solution and the solution itself will become cloudy. You will also be able to see a white residue, powder, or bubble forming on the bottom. That is the chloroform.
After the time has passed, the reaction should be completed. The Chloroform will be at the bottom of the container. Pour out the excess bleach that is on top while being careful to leave the Chloroform in the container. Pour out as much bleach as you can without wasting any Chloroform. When you’re done pouring, transfer the rest of the container to your separation funnel. Let it sit there and settle for 10 minutes. When it is settled, drain out the Chloroform. All that is left should be water from the ice if used.
THE RESULT IS IMPURE OR COMMON CHLOROFORM AND IS NOT SAFE TO BE USED ON HUMANS OR ANIMALS. DISTILLATION IS NEEDED FOR DISTILLED CHLOROFORM.
Storage As mentioned, if stored improperly, Chloroform will degrade into a poison over time. In order to store Chloroform, place mixture in a dark container or dark storage area with no light, make sure the container is air tight and vacuum sealed.
