I'm coming to a point where I might very well have a surplus of vapored pure or high concentrated Iodine.

solution A and B are mixed under mild heat and shazam, iodine vapor, only problem is I don't have glassware or contain the knowledge of how to properly condense iodine.

I have one theory of using a wine bottle system very similar to the P/P synth where A and B are seperated through an inert mechanical device inside and channeled through a rubber stopper/pvc hose into a chilled wine bottle roughly 40 degrees F. filled with acetone (I'm thinking at the moment correct me if this is a bad choice) I plan to keep the pvc into the condensing outfit without a stopper in the case of any vapor impurities that happen to be uncondensed will leave the auttomatically.

well thats my experimental I2 synth please give me advice on wether this is a possible/dangerous/good/retarded/misinformed idea TY

btw I may have some *spare* resublimed iodine in the near future if anyone has anything they would like to trade with, but thats if this works.

can anyone at least recomend an iodine friendly solvent?

The easiest way I've seen yet is to acidify

tinctures with hydrochloric acid then add H2O2 untill i2 reappears on top.

TY for the reply but, I'm not talking tincture, just vapors=>crystals.

thats all I care about I have plenty of VAPOR at my disposal I just need an effecient safe way to condense it into I^2. Like I said before I would like to know if forcing the vapor through a glass bottle/rubber stopper/pvc tube into acetone or better yet distilled water, would be an ok way to collect some I2 crystals.

chloroform is an excellent iodine solvent. Ether should work, and so should ethanol. Water isn't a very good iodine solvent.

okey dokey, but the acetone or distilled water would make a good an okay iodine condensation liquid? I can worry about resubliming/purification later.

PS thanks for the input. I'm going to have lots of CHEAP pure I2 is this works.

Iodine is mostly insoluble in water. It dissolves good in alcohol.

hey sheep--

Been thinkin about your idea. It seems that you may be close or have access to some kind of industrial facility or something. Its hard to come up with an idea without knowing or at least having some idea of where and how the "vapors originate.

So lets say that they are the byproduct of some kind of manufacturing process. The best way would be to capture the vapors or whatever they may be called (vapors suggest heated or at least it does to me) and then extract the "goo" from the media, then convert to crystals.

Like I said, its too hard to help you with a device without knowing the wheres and the hows.

Throw me a friggin' bone here.

sounds to me like he has iodine in a vaporisor and when heated with an alcohol it fumigates into a non open area within his

labware...he wants to know how to re-condonse it pure. but the way he's stating

it being iodine vapor I personnally don't

thuink it can be condensed to pure. he needs

to route the gas(iodine vapor) to something

that will atract the ions then further collect.

no secret or industrial ties or anything really rare like that. I have quite a bit of industrial waste handy, it seems amoung alot of carbon, roughly 80% and some other trace components including iron, sodium and chlorine there is a resonable portion of sodium iodine making the -isolated- iodine content somewhere between 8% and 12%.

I understand there are far more iodine potent mixtures available over the counter for not much money however, please bear in mind this dry mixture is VERY available at a near free cost in almost a lifetime supply.

My original plan was take the mixture and add 93% sulfuric acid in room temperature and low heat if yeild-effeciant. This according to my research will expell signifigant amounts of hot vaporized iodine estimated 50%-70% of all iodine present in the original mixture.

My current plan is to add a third compound of magnese oxide to help draw out the iodine at an estimated 90%-95% of all iodine present pre-reaction.

2 I (-)+ MnO2 + H(+) => Mn(2-) + 2 H2O + I2

I must stress I have no glassware so I was going to borrow some famous P/P phed symth teqniques. ie: I.W.M. (industrial waste mixture) is placed inside a wine bottle with a small glass container, very similar to a cheap shotglass contain the 93% sulferic acid. At this point the bottle is corked with a rubber stopper and PVC tube leading to a chilled container of distilled water roughly 35-40 degress farenheiht the container is not compleatly attached to the pvc tube leaving an escape for any unwanted vapors unable to condense within the distilled water. The bottel is heated to where the area directly surrouding the compounds are 120-150 degrees farenheiht. the glass sperator still inside the wine bottle is tipped over into the I.W.M. mixing the sulfuric acid, hopefully at this point releasing iodine to be channeled into the chilled water where the now crystalized iodine can be collected/processed resublimed/packaged, traded/sold on totse for somthing less avalable to blacksheep.

It appears that you have one major problem. A MIXTURE of industrial waste means that there is "God knows what" in there along with the iodine. If you add sulfuric acid to the mix, there is a strong possibility it will react with other constituents in the waste mixture, causing one of three things to happen

a) the iodine is the only thing that reacts and everything goes as you planned

b) other things react with the acid causing the iodine to react unpredictably

c)other things react with the acid creating toxic or violent eruptive reactions and possibly causing death to whoever is nearby.

Its that last one that you really have to consider before you actually do this experiment. If you have a shitload, then try a small trial size in an open field or the dump and see what happens.

Are you sure sulfuric is the best acid to use for this purpose? Plain ole hcl may be a better choice. I am no authority on the matter, but have created many devices and pieces of equipment to aid in things of this sort. Sorry, but my mind can't visualize this operation at this time. If it hits me, I will surely let you know.

Oh yeah, 8-12% is pretty friggin' high if you ask me. Usually 7% is about the best you can do. Some of the privledged few can get 12%, but thats as high as I've ever heard.
