And if so could I make bromoform byĪdding sodium hydroxide to bromine and acetone in water? What about the bleach method and bromoform, can we expect the same problems with iodoform? I don't see why not. Guess it was too good to be true, sorry if I ever doubted you woelen. Produced was a problem and making mixed halogen haloforms. I tried the bleach method and was really happy with the amount of product I got compared to your method woelen. Maybe I should, and force myself to learn something I can't believe I didn't read this thread before my iodoform experiments, but I hardly ever go in the organic section here as I usually don't know That no CCl4 is formed, but only CHCl3 and possibly lower substitution products like CHCl2I and CHClI2. Based on the results of this experiment I'm almost 100% sure The second experiment describes what happens when chlorine gas is passed over iodoform. I found it sufficiently interesting to make a small (text-only) web page about this experiment: I have done a few experiments to check what happens with this I also received a few questions about the reaction of iodoform with chlorine gas. Of acidifying, oxidizing and basefying becomes too much for the small amount of iodine used for making more iodoform. Three steps most likely is most economical, above that, the hassle In a single step,ĥ0% of the iodine is used, with two steps, 75%, with three steps 87.5% and so on. ![]() Posted on 10-6-2011 at A few posts earlier I explained how most of the iodide in the remaining solution can be used for further haloform reaction. Thanks!ĮDIT: Looking up BPs, it may be possible to distill off the acetic acid and leave behind sodium iodide, but there may be more interactions here that This looks like a dead end, but I thought I'd ask a more experienced group. Mechanism has many stages (see the above link). Also, things may be more complicated than this, given that the haloform The least soluble combination would seem to be sodiumĪcetate, but that's the least interesting thing we could recover IMHO. Left with an aqueous solution of the remaining ions. Assuming we wash the CHI3 with water, we are My question is whether or not anything else can be recovered on the right hand side of the equation. Assuming we use acetone as the reactant/solvent, and NaOH as the source of OH-, and strip out/balanceĪll the stages of the mechanism, we get the following balanced equation:ģI2 + CH3COCH3 + NaOH -> CHI3 + CH3COO- + Na+ + 3I- + 3H+ ![]() I've been reviewing the haloform reaction and Woelen's preparation. I would have expected an article like this (Phones death)īringing up this iodoform thread again to ask about purification. Death by phosgene is probably one of the most atypicial ways for a 16 year old to kill himself so I'm suprised it didn't I am very surprised I cannot find a single reference online other than hearsay (Just2DIY on yt and him being The lungs can't survive that long filled with HCl. ![]() Symptoms of pulmonary odema can take a little while to manifest. I was only worried in the 24-72hour bracket where the I didn't smell hay so I doubt there was over 1ppm entering my nose and even so it was days ago. The Iodoform was slightly wet and heated strongly with a blow torch.Īnyway, this issue no longer concerns me. Out my lab which is in a fairly confined space (I usually work outside). If I dissolved it in propanone and flushed it down the sink it would have stank I heated it because I thought that was a good way to dispose of it. "Hey its 2 centuries and I'm still alive!"(But answering from the other side, everything is fine, I play with Adam and Grand-Grand-Pa and Mom)" Knew that iodophosgen had injured me in some way" "Heeeyyy iiittttsss 1111 ccceeennttuuurrryyy aaannddd III''''mmmm sssstttiiiillll aaallliiivvvveeee!!!! (But I suffer from Parkinsonian disease.I ![]() I think he suffers from the survivor paradox symptom Two of themĪre still alive and well after 85+ years, so all chemicals can't be as bad as the media claims. Issues from chemical exposures are very hard to detect by X-rays.īut I know several chemists who have had many exposures to harsh chemicals and if they were fine after a couple of days, they were OK. Meaning that if you had symptoms, then they might be due to physical problems that show up on an xray. Without symptoms, most X-rays will not likely showĪnything useful. Should i get my lungs x-rayed?Ģ) If you have no symptoms and are alive, then you will not likely suffer any ill effects. I cleaned it with a paper towel and burnt said paper strongly with the bt. With the blowtorch there was some mess on the pan. So just to confirm 44 hours and nothing means im fine? I also forgot 2 mention that after heating it I thnk you should make a difrent thread for that.
