Mendelejev Posted June 4, 2005 Share Posted June 4, 2005 I would like to make H202 with very cheap chemicals. Also NaI ! Does someone knows a good method ?? Link to comment Share on other sites More sharing options...
akcapr Posted June 4, 2005 Share Posted June 4, 2005 pehaps a displacement reaction of some kind for the NaI? Link to comment Share on other sites More sharing options...
akcapr Posted June 4, 2005 Share Posted June 4, 2005 HI + NaHCO3 → NaI + H2O(l) + CO2(g) Link to comment Share on other sites More sharing options...
jdurg Posted June 4, 2005 Share Posted June 4, 2005 2Na(s) + I2(s)[in excess] -> 2NaI(s) Just make sure you do this experiment in a large, heat resistant container and that the sodium you use has had the majority of its oxide coating and oil removed from it. Then you put the chemicals in the container and heat it up until the activation energy barrier is met and the reaction proceeds on its own. Some may say that you need to initiate the reaction with a drop of water, but that can create some contamination with sodium hydroxide. Link to comment Share on other sites More sharing options...
budullewraagh Posted June 4, 2005 Share Posted June 4, 2005 it's much easier to get NaI than HI, Na and I2. just buy it. HI is controlled in the US because of its ability to, when used with rp, reduce ephedrine. I2 is hazmat to a degree and sublimes. Na is, well, Na. reactive metal. NaI is a pretty harmless salt Link to comment Share on other sites More sharing options...
H2SO4 Posted June 4, 2005 Share Posted June 4, 2005 You can probaly get NaI as a household product at an aquarium store or something. Link to comment Share on other sites More sharing options...
akcapr Posted June 5, 2005 Share Posted June 5, 2005 ya. i knew the na+i method (duh) i just dint think someone would get sodium and iodine and combine them. I dont really recommend doing that. Link to comment Share on other sites More sharing options...
woelen Posted June 5, 2005 Share Posted June 5, 2005 I would like to make H202 with very cheap chemicals. Also NaI ! Does someone knows a good method ?? If you look for NaI, KI probably will be OK for you also. KI can be purchased online at virtually every raw photography chemical supplier. They sell to individuals. Some addresses: http://www.artcraftchemicals.com http://www.jdphotochem.com Beware, however, KI is not really cheap at $15 to $20 for 100 grams.

akcapr Posted June 5, 2005 Share Posted June 5, 2005 in the first link, its hard to belive all those chems are used for photographic purposes Link to comment Share on other sites More sharing options...
budullewraagh Posted June 5, 2005 Share Posted June 5, 2005 at the second link i found indole and tetrahydrofuran. see, that's confusing. indole is legal? people can just buy it and make any sort of tryptamine. and THF? great for certain organic syntheses Link to comment Share on other sites More sharing options...
H2SO4 Posted June 5, 2005 Share Posted June 5, 2005 the first link has lots of pyro stuff (i.e. lampblack, "book of pyro" lol.) Link to comment Share on other sites More sharing options...

Look at the list of chems I have ordered online in the last 7 years and which I now have in my home lab. http://81.207.88.128/science/chem/exps/expadd.cgi?compounds=list I think that 75% of all these chems is from photography suppliers, and from that 75% a large part is coming from the two I mentioned earlier. In fact, some of the chems I do use for photography, but some I just ordered for playing with in my home lab. If I order chems, then I order many chems in one go and 10 - 100 gram per chem. That keeps costs acceptable and besides that, what is the use of having a pound of NaCN around, just for performing some experimenting? I do microscale experiments. If you are in for pyro, then the photography suppliers are not the place to buy from. Purity is high, but prices are too high for pyro-applications. I'm not a pyro-man, so for me it is exactly what I want. Link to comment Share on other sites More sharing options...
Hephaestus Posted June 8, 2005 Share Posted June 8, 2005 If you enjoy sushi or are near the sea, grab some seaweed. Dry and burn. Gather the ashes which contain plenty of I- and oxidise with bromate, permanganate, dichromate, cupric salts or chlorine. Place a watch glass over the beaker with ice on top. I2 forms on underside of watchglass. If react with sodium NaBrO3 get nice NaBr too. Reaction with NaOH: I2 + 2OH- = I- + IO- +H2O Ive always wanted to use IO- for something...

akcapr Posted June 8, 2005 Share Posted June 8, 2005 the iodine would actually sink to the bottom, unless heated maybe Link to comment Share on other sites More sharing options...
Hephaestus Posted June 8, 2005 Share Posted June 8, 2005 yes, only slight heating needed. Link to comment Share on other sites More sharing options...
Mendelejev Posted June 9, 2005 Author Share Posted June 9, 2005 Mmm, thanx a lot for the information. But don't forget H202. Are there simple and cheap methods for his synthesis ?? Link to comment Share on other sites More sharing options...
akcapr Posted June 9, 2005 Share Posted June 9, 2005 burn water in oxygen ;-). (jk) Link to comment Share on other sites More sharing options...
budullewraagh Posted June 9, 2005 Share Posted June 9, 2005 h2o2 synthesis is really impractical for the home lab. theoretically, one could possibly do it, but it would be remarkably difficult and would require a plasma arc. Link to comment Share on other sites More sharing options...
Mendelejev Posted June 10, 2005 Author Share Posted June 10, 2005 Mmm, a plasma arc. Don't think I've got that in my lab. Link to comment Share on other sites More sharing options...
budullewraagh Posted June 10, 2005 Share Posted June 10, 2005 you can make one. i know of someone who made a birkeland-eyde reactor at home Link to comment Share on other sites More sharing options...
akcapr Posted June 11, 2005 Share Posted June 11, 2005 makin h2o2 definately impractical, defiantely Link to comment Share on other sites More sharing options...
budullewraagh Posted June 11, 2005 Share Posted June 11, 2005 hardly, but whatev. if you really want to, you can, and it's not particularly expensive Link to comment Share on other sites More sharing options...
Mendelejev Posted June 11, 2005 Author Share Posted June 11, 2005 Think I'll just go to the chemistry shop (Don't have friends with a Birkeland-Eyde reactor at home ) Link to comment Share on other sites More sharing options...
