Hydrogen iodide(HI)

This is the best way to do it:



Making Red Phosphorus:
The striking pad on books of matches is about 50% red phosphorus. The determined experimenter
could obtain a pile of red phosphorus by scraping off the striking pads of matchbooks with a
sharp knife. A typical composition of the striking pad is about 50% red phosphorus, along with
about 30% antimony sulfide, and lesser amounts of glue, iron oxide, MnO2, and glass powder.
I don't think these contaminants will seriously interfere with the reaction. Naturally, it is
a tedious process to get large amounts of red phosphorus by scraping the striking pads off
matchbooks, but who cares?

Making Hydroiodic Acid:
This is made by mixing iodine and red phosphorus. When making hydroiodic acid from iodine
and red phosphorus, the acid is prepared first, and allowed to come to complete reaction for
20 minutes before adding the ephedrine to it. The way around the roadblock here is to just
boil off some more of the water from the ephedrine extract, and make the acid mixture in fresh
pure water. Since the production of HI from iodine and red phosphorus gives off a good deal
of heat, it is wise to chill the mixture in ice, and slowly add the iodine crystals to the
red phosphorus-water mixture.


But are there some other way to do the HI?

Detritus alert!

How does one make HI From I and P?

That bit works.
It is just scraping red phosphorous a few hundred mgs at a time from match books does not bear thinking about.
That and extracting pseudoephedrine from hundreds of decongestant tablets.

OP didn't mention water, just mixing I and P.

To be honest I doubt he knows what he is talking about. I assure you that water is needed.
Here are some recipes;

I speak about HI not of meth....

The synthesis is very much an easy with HI .

C10H15N


With "efedrina" or "pseudoefedrina" (C10H15NO) adding simply Acid Yodhídrico (HI) it remains metanfetamina (C10H15N).

It is to say adding the Acid Yodhídrico it him goes away O and stays d-metanfetamina.;)

You say its on the match box... then how come it says on wiki that its in the match head or am i wrong?

The majority of modern matches are a KClO3 tip (hide glue & burn-rate additives) the the dark maroon "striker" has a small amount of red P in the milligram level (see: H. Ellern, Mil-Civilian Pyrotechnics). There are gram level sources of Red P if someone needed large levels to do mid-size experiments. There always have been MUCH better sources. There's also the several synthesis that people here have worked with.



On another subject....
ARE WE COPY-PASTING FROM A DRUG SITE?

Hence my confusion, had no idea where hydrogen was coming from.

You might be able to use sulfur instead of phosphorous.

“Disulfur diiodide, S2I2, can be synthesized by the reaction of S2Cl2 with HI in CCl4 at room temperature, or better, by the reaction of HI with S2Cl2 in Freon at −78°C. en hyphen deg . In the latter case, it is obtained as a solid, which slowly decomposes to sulfur (especially S6, S7 and S8) and iodine above −30°C. The compound sulfur diiodide does not exist. Although iodine does not react with sulfur, these elements do form compounds in solution in AsF5/SO2.”
Inorganic chemistry. Egon Wiberg, Nils Wiberg, Arnold Frederick Holleman

Disulfur diiodide could be reacted with water to form hydrogen iodide. The equation for S2Cl2 with water is
2 S2Cl2 + 2 H2O → SO2 + 4 HCl + 3/8 S8.

Why does sulfur diiodide not exist?

Original post has little to nothing to do with the title. Just another methamphetamine cook looking for recipes.

Reported as detritus.

It's up to Mod's and Polverone to decide, however.

:):) Im not looking for any metanfethamine,its easy to do the meth and the products are easy to get here in Spain,im only want to learn....

Yeah, yeah. And there's free <a href="http://lmgtfy.com/?q=cocaine+madrid+air">cocaine in your air</a>, but that's beside the point. Your post is about methamphetamine production. Many--but not all--of us don't take too kindly to that sort of interest here. If you want to prepare hydrogen iodide, I suggest you do a literature search before posting a vague "But are there some other way to do the HI?" You've put in no effort on your own, why should we help you?

[edit]

You're not making a very good <a href="http://www.sciencemadness.org/talk/viewthread.php?tid=17825">introduction for yourself</a>, are you?

Hi anonymous201,

I am afraid that you have preemptively derailed your own thread by mentioning ephedrine and HI in the same post, probably because you just copied from one of the first Google hits for "hydrogen iodide synthesis." Hydriodic acid can also be prepared by the action of hydrogen sulfide or lower-valence acids of phosphorus on iodine. You can find a lot of examples of the hydrogen sulfide procedure in older laboratory manuals from Google Books, but heed safety warnings; hydrogen sulfide is very toxic. In the future please do a bit more research before asking members to answer your questions, and leave street drug chemistry out of your queries. Nowadays it is easy to search huge collections of digitized books and articles without ever stepping away from your computer.

I am closing this thread because I think it cannot be redeemed at this point.
