How to extract iodine crystals from a povidone-iodine solution?

[Haruwua]

Heyo! How do u extract iodine from an 11% povidone-iodine solution?
I followed the guide for extracting iodine from an alcohol solution using a polyethylene plate and water but that didnt really work out.
I do have some sodium hydroxide but i sadly dont have any hcl acid, nor any hydrogen peroxide to try out. Are there any other methods i can try out? I want to use the iodine for the red phosporus meth synthesis.
Appreciating any help!
Greetings

I would try to separate it via DCM and drain bottom layer out and see what will happen

There was a method where Fester captured the loose iodine in toluene or petroleum naptha. He did this with sodium hypophosphate, or hypophos- acid but I believe it will work with RP in water. So anyway, you add the iodine in toluene solution to RP in water, ideally you have a magnetic stirrer and eventually the iodine in the toluene gets reacted with the RP and creates an HI in H2O solution, which will have to be filtered and seperated from the rest, or most likely and better yet, distilled. You can tell when the iodine has been reacted/all used up when the toluene goes from purple iodine color back to a clear solvent color.

You have to get the iodine to precipitate to some extent, I think, before you can capture it into solution. So I don't know if it will work without HCl or H2O2. Sodium hydroxide is used in the povidone-iodine solution to activate and seperate all the gak that builds up.
I don't have any idea what could be subbed for HCl acid and hydrogen peroxide. I don't really understand how this works, I just know how to do it.
Good luck! o7

Recently i had the same tought and found a nilered video to it. Will post it in videos soon, will be important i guess bc typical iodine tinctures arent existent abymore at least where i live. It was something with peroxide and smth else which in theory first seperated iodine and povidone with distillation afterwards but i dont remeber. Will live forever in video category :3>

The betadine (povidone-iodine) and regular iodine tinctures use the same process. Only with the povidone you add NaOH solution and reduce the volume, the polymer will precipitate for decantation. Then you use HCl and H2o2 to precipitate the iodine and filter that out. The crude iodine can then be futher washed and purified for use in Nagai method.

use Hydrogen peroxide
(or chlorine-household bleach...)
and Hydrochloric acid....l

et it settle --
filter quickly...

then watch "resublimation" tutorials on youtube.....


and be quick and prepared to feel lachrymatory ( tears running / nose running / diffic.to breathe etc.) effects....its doable although...try to find Potassium-Iodine (powder or hi dose tablets) is less a hassle

 

[W.P.3]

Bleach + HCl is a very bad idea my friend

 

[Eleusius_hive_reboot]

sodium hypochlorite in acidic medium is nasty (like i mentioned above, wise master....dammit)
>>lachrymatory properties.....
but it is also very doable in a moderately ventilated area

we give clandestine OTC-preferably solutions for
people in need .... i am a very responsible academic higher graduate in organic synthesis and other disciplines...as well as very in picture how cooking in ghetto prep.level looks....

harm reduction is always priority.....but yeah obviously you are so far gone....i mean ahead...sorry....so illuminate me master chemist....please, what does the method bring upon us unworthy street maggots? (not that 1000 random blokes on youtube showed this but they surely died ....if you say so...

and i wouldnt dare considering myself a friend of the holy chemistry entity....so FOR YOU ITS " A bad IDEA MISTER, (even Dr.) Eleuzius" clear?

 

[W.P.3]

Sorry, I didn't meant to harm your ego.
I was just saying that most people on this forum won't read your message entierely and even if they do, you did not mentioned ventilation or mask use in the first half, you simply wrote "be prepared" and "be quick" which are not sufficient. I mean, being prepared will harm you anyway...

Is this even a feasible method? Just based on my limited knowledge of what a povidone is I'd expect the yield of this extraction to be extremely low and completely unfeasible given the price of the source material. There must be a dozen of better ways to get iodine than to extract it from a povidone solution.

For the kemistz in the USA that can't buy I2 crystal without bringing attention, it is something. I try to get people to think "if you didn't have to pay for it, would it be worth it?" then it comes down to yield and other things, but, at some point you are just happy that it works and you can continue your quest. This is who this is for. Obviously, if you are competent at doing total synthesis routes, going back and scraping matchbook is anathema. It is much more important for me to know how these things work, how they can be used, etc. than the product that comes out at the end, you know?

To answer your question. No. You could buy an oz and have it mailed to you for less cost and time than it would take you just to go buy the iodine to make an oz and do all the work.

For the new bees learning to make honey, reducing pseudo with OTC products is probably the best place I can suggest for someone to start. That was the goal I set for myself - "I am going to reduce pseudo one way or another or I'm gonna die trying." So I am out grabbing boxes of matches and lithium batteries not knowing there are two different ways, but I figured that out, of course. How to extract, purify, clean, wash + dry all the ingredients, concepts, techniques .. lab etiquette.. get "the novice mistakes" out of the way, you know? You know what the end product is supposed to look like, so if you can replicate that with stuff you got from the grocery store, then you're a pretty worthy cook in my eyes. If you fuck it up, the main thing is noone got hurt, but the ingredients and gear are inconsequential.

If I missed the part that said this was only a thought experiment then you have a point.

But I didn't see such a remark and I imagined some punk kids buying liters of Betadine to extract few grams of iodine thinking how smart they are.

 

[Eleusius_hive_reboot]

I agree here with you Soldado
--> I personally thinlk anyways that the Birch - Ghetto Method is to high in terms of risking to hurt others
and ofc yourself ...
you stated as well , priority no.1 is to let no one pay for your fuckup who hasnt deserved it or you stated something in this direction i am obviously a man of hurt EGO as you know me all here, like the critic from before mentioned.

but besides, is the US Betadine Polivinyl-pyrolydione-iodine only ? were having potassium iodide as crystaline supplement in pure form.

and a expensive tincture with potassium-iod. and free iodine + some other shit aiding materials ......

as for the phosphorous its way less required if you add Phosphoric -Acid / water + fine active charcoal.


I did blend matchbook striker with my ephedrine shrup blender one time just to see if this would work as catalyst with the acid and carbon -> i ONLY WASHED THE PAPER - POWDER with a splash acetone/water and squeezed the sludge out with a glove - by hand....i had to piss my pants almost, how well this worked comparing to my expectation.....so use PSEUDO and the LWR HI/P as number one choice

I do appreciate your posts from what I have seen so far, Mr. Eleusius_hive_reboot. Even when you lose your patience and have to make an example and burn one of these lazy, incompetent, blood suckers for everyone to see to prove a point from time to time. For me it is entertaining, I get it. I have to do it also, embarrassingly, for everyone to see, in hopes that others will learn something about what it takes to succeed in the chemistry realm via the self taught route . You are quite more knowledgeable and experienced than me in terms of chemistry, so I am happy for your comments. Thank you.
Love and respect to all.

Some people, you can have a big disclaimer on the front cover. A warning in the fine print on the back. You can drive it to them, and knock on the door and beat them over the head with it and say "HERE IT IS!" and they still don't get it. Again, my friend, if you can't imagine a scenario where there could be any reason whatsoever to knowing this information, then I don't know what else to say, I can't MAKE you understand why other people in other places on earth do things differently from each other. I tried to spell it out for you and give you an example of why anyone does or would want to do or know or try this, even though it's far from my priority or responsibility. Yet, you continue with the mocking tone, like I have to justify the existence of the materials as if you are the only person in the audience, when I had already said basically 'this isn't the best method - it would be better to just buy the product'. Did you miss what the title of the thread was? Other than an experiment in the futility of explaining and the endurance of ones patience, what exactly is your point? The method works, if it doesn't make sense WHY you would do it, then it isn't for you, don't worry about it.

If it is worth doing is a question you should be asking yourself, not people at BB. For most of us, like I said, you could buy an ounce of finished product for what it would cost to buy probably not even enough povidone to get the iodine you would need to do the reaction to make an ounce of meth. It is worth doing it for me once in a while, and I'm not going to say how or why. I don't know about you or anyone else.
