In this video I will show the synthesis of Iodoform by the haloform reaction. This is the synthesis I got from the sciencemadess member woelen Take 1.4 grams of potassium iodide. Add 10 ml of 10% HCl or 10% H2SO4 and dissolve all KI. Add excess amount of H2O2 (eg 10 ml of 3% H2O2), such that all iodine precipitates and only a fairly light brown solution remains. Let iodine settle, decant the solution, add a lot of water, let iodine settle again, decant the water, and then add 1 ml of acetone. Swirl and let as much as possible dissolve. No need to have all of it dissolved, the iodine is somewhat flocculent and is not compact. Add 10 ml of water and then add the 5 ml of NaOH-solution with 0.5 gram of NaOH. Just over 0.5 grams of CHI3 will precipitate. Again you can scale up. If you don’t have H2O2 use bleach as oxidizer instead, but assure that no excess is added. Excess bleach redissolves the iodine and will lead to chloroform and mixed haloforms. For this reason the use of H2O2 is highly recommended. Excess H2O2 does not redissolve the iodine. Keep in mind that only 50% of the iodine is used. After precipitation of the CHI3 you can collect the remaining iodine with acid and H2O2 and use that to make more CHI3. See above in this thread. Spread the CHI3 on a piece of filter paper to have almost all adhering water absorbed in the filter paper (coffee filter is perfectly suitable for this, but do not use paper tissue or toilet paper). Scrape the solid from the filter and …
