ISO-SWIM decided to try a new twist on the Methyl Man Nitro writeup. ISO-SWIM decided that instead of using HgCl2, he would try Hg(2?)I2 instead(mercury blobs dropped into I2 tincture, ala unnilhexium). The batch was done at a half scale, 12.5g ketone, 10ml MeNO2 and 13.7g aluminum foil. The tincture, .24g Hg from a thermometer dropped in a 30ml 3% I2 tincture 1 week earlier, was dissolved in 400ml MeOH, and dumped into a 2L RB flask, to which the aluminum and a 2.5 inch stirbar had already been added. Amalgamation took approximately 35-40 minutes, and once complete, the ketone/nitro was dripped in. Do not wash the aluminum after amalgamation, this was tried and resulted in a failed run, without ever heating up appreciably during the addition. The ketone was dripped in over the course of about 15 minutes, and the reaction proceeded as expected, and reached an impressive reflux. The rest of the procedure was carried out as MMs writeup, and yielded 10.9g of the hcl salt. Just in time for the weekend

I believe it came from TSII. Do a search on "HgI2" if you need information. BrightStar mentioned it being the least desireable of the Hg salts for amalgamation, but that was in relation to water solubility. Hellman had a thread on it several years ago, but it has been purged.

I guess TFSE isn't working properly, I couldn't find the post, but it was on a thread about peracetic acid, where unnilhexium made mention of his amination technique using I2 tincture. I don't know if that was a unnilhexium original or not, he was just the first bee I saw posting about it. Anyhow, for those of you worried about side reactions, the residual I2 seems to form some kind of alu-halide, as the red color leaves the solution during the amalgamation. Also, the tincture adds about 15ml of water to the reaction, which should keep Osmium off your case
BTW, it important to periodically shake the tincture bottle, to break up the mercury blob so that it can react. Also, make them as far in advance as possible. They can be made weeks, months or years in advance, IT'S JUST TOO EASY!!!!!!!!!!!!! Isn't that so much nicer than making or buying HgCl2?

BTW, here's what unnilhexium told me: "All aminations were of the al/hg variety, using methanol as a solvent (isopropanol was never used successfully), with ~.5 gram blobs of hg dropped into I2 tincture, allowed to react for a few days, and then used to amalgamate.
Swim recorded an actual amalgamtion time, it took 17 minutes(.5g mercury blob, 30g Al). The basic procedure is to put a plastic dish on the old balance, zero it, and poke at a mercury blob until about .3-.5 grams is weighed out, then dump it into some 2% I2 tincture, the kind you buy at walmart. I can't verify that HgI2 is formed, but I have successfully amalgamated using this procedure."

Its interesting what you find in the trash these days...
"A very small amount of elemental mercury was added to 2 molar equivalents of iodine crystals in a closed container and gently shaken. A clumpy crimson powder formed over the next hour. Visual inspection indicated that a small portion of unreacted mercury and iodine was trapped in the clumps, so a few drops of methanol were added. All clumps disappeared and the components went into solution. This mix was added to a larger volume of methanol, and the experimenter noticed a very small portion of greenish-yellow solids remained undissolved in the bottom of the flask. This was assumed to be mercurous iodide (versus mercuric). Al foil was added to the flask and amalgamation began in earnest in less than 2 minutes time (probably owing to the large volume of Hg salts present). The experimenter concluded that the HgI2 formed was completely viable."
One would assume that I2 tincture should behave in a similar fashion.

Only thing I would like to add to this thread:
Do you realize that when you dump ANY amount of fluids containing fluidal mercury in your wash table's drain pipe, that that fuckin mercury is so damm heavy, it will stick at the bottom of the first S curve it finds, and that is the one which will over time dry out when you don't use your lab frequently, thus giving the mercury all the time in the world to EVAPORATE into your precious little lab, and then, when you enter after a summer of love, your playground again, it will be taken up in your lungs, AND NEVER LEAVE THEM EVER AGAIN!
There used to be a little thread around here telling the story of a full proof professional researcher, a woman btw, who slowly showed all signs of mercury poisoning and didn't understand them, until too late, she DIED.
Look up how much elementary mercury your precious life system, called body, can afford.
Be prepared to get a shock.
Don't play around with elementary mercury, if you are a total newbee.
Lugh somewhere gave some basic rules for handling mercury and mercury spills, a must read for all those who read this thread. There is a simple way of getting rid of elementary mercury, by turning it into a not very toxic salt, so find that thread! Think of iron. LT/

Holy shit! ISO-SWIM goes on a synthesizing binge, and comes back to see this thread has doubled in size. Anyways party people, this is not hard. For one, you will never know how much of the hg actually converts to the salt, and two, this reaction is not THAT sensitive to the amount of Hg salt used. ISO-SWIM has had consistent success for anywhere from .2 to .5g blobs of mercury, for a standard size MM nitro/al-hg. As my stoichiometry skills have calculated, 1 30ml 3% I2 tincture can process .5g of mercury. It just happens that it only takes one tincture. Trust me, a range of .3 to .6g of mercury will work, as long as the tincture is allowed AT LEAST a few days to stand. ISO-SWIM has already done a half dozen more of these, and this procedure is BULLET-PROOF. ISO-SWIM has had a 100% success rate. BTW, please report on your successes, this is a good procedure, so I don't want this thread to sit here for two years before somebee trys it.

Molecular Weight: 271.52
Routes of Entry: Inhalation: Yes (Weiss 1980, p. 581)
Skin: Yes (*Gosselin 1976)
Ingestion: Yes (*Browning 1969)
Health Hazards (Acute, Delayed, and Chronic): It is classified as
extremely toxic. All forms of mercury are poisonous if absorbed. Probable
oral lethal dose is 5-50 mg/kg; between 7 drops and 1 teaspoonful for a 150
lb. person. Mercuric chloride is one of the most toxic salts of mercury
(*Gosselin 1976). Material attacks the gastrointestinal tract and renal
systems (*Friberg 1979).
Extinguishing Methods: Some of these materials may burn but none of them
ignite readily. Extinguish with water spray, fog, foam, dry chemical or
carbon dioxide (*DOT 1984).
Unusual Fire and Explosion Hazards: Material may explode on heating, with
friction, or contact with alkali metals, sulfides, acetylene, ammonia, and
oxalic acid (*Rumack 1975 to Present).
Stability: Unstable:
Stable: Yes (Weiss 1980, p. 581)
Conditions to Avoid: Mercuric chloride may explode with friction or
application of heat. Mixtures of mercuric chloride and sodium or
potassium are shock sensitive and will explode on impact (*NFPA 1978).
Avoid contact with acids or acid fumes (*Sax 1975).
Incompatibility (Materials to Avoid): Formates, sulfites, hypophosphites,
phosphates, sulfides, albumin, gelatin, alkalies, alkaloid salts, ammonia,
lime water, antimony, arsenic, bromides, borax, carbonates, reduced iron,
copper, iron, lead, silver salts, infusions of cinchona, columbo, oak bark
or senna, and tannic acid (*Merck 1983).
Hazardous Decomposition or Byproducts: Upon decomposition highly toxic
chloride and mercury fumes are emitted (*Sax 1975).

SWIM has studied and searched fairly well. Don't think real good answer is out there. SWIM sees about 5 different options. Has no idea which ones are right.
OPTIONS:
1. All the Hg is already converted by the Nitro Al/Hg. Place sludge in milk jug and throw away.
2. Seperate the Al particles and place in jug, flush the liquid
3. Place more Al in the sludge, let stand for 5 - 8 hours, seperate, solid in jug, liquid gets a flush.
4. Mix suflur Powder in the sludge and flush.
5. Mix Iron/Steel turnings in the sludge and bottle and toss.
A lot of methods keep talking about recovery of the Hg but don't think that is goind to happen here.
Also confused that if Al will react all Hg then seems way to easy to just add more Al to make sure and throw away. But if that were true why are there so many posts on these other methods.

Disposing of mercury wastes into the water shed is not only bad for the environment, but totally unnecessary. Your basified sludge contains elemental mercury, which will amalgamate to metals such as iron, zinc or copper. You take a 20 L/5 gal bucket with a tight fitting lid, throw some clean metal turnings in the bottom, and then your pH 13-14 sludge. Attach the lid firmly. Over a period of time, the mercury is amalgamated, siphon the sludge for disposal down the drain. Keep the lid on the bucket for future use. If you're determined to dispose of the mercury instead of recycling it using nitric acid, you will need to solidify the turnings within plastic, thus isolating the mercury from the watershed. This would be most easily done by slowly portionwise (so as to avoid melting the bucket) pouring molten plastic into the bucket until the metal turnings are completely encapsulated

You probably won't want to bother with recovery until you've got more than a couple of grams amalgamated. You will want to keep the lid on tight to prevent the escape of mercury vapor. While SWIL has never done the recovery, obviously because of the volume of turnings compared to the amount of mercury, one would want to use very dilute nitric acid, and then evaporate the solution to obtain the mercuric nitrate.

Superstar: It might be harder than you think to pour off the tincture without dumping the blob as well. It's easy just to zero a plastic container on a balance, and have another container with the mercury. Just tip the container poke the Hg with a glass stir rod until you pull a .3-.5g blob into the container on the balance. Dump it in the tincture, replace the lid and shake the fuck out of it to break up the blob, which increases the surface area of the Hg. ISO doesn't think mercury vapor is TOO much of a risk, mercury having a high B.P., and probably creates very little
vapor at room temp. and atmospheric pressure, but ISO doesn't know that for a fact, so someone flame the fuck out of me if I'm wrong.

Mercury spills can be easily neutralised with Chemizorb® Hg absorbant. This kit is supplied by Merck and can be used to neutralise the contaminated area up to 1 m2. But probably you won't be able to get it, so here is an OTC version of such an absorbant:
Cleaning up Mercury spills:
First collect the drops with a pipet, put them in a bottle and seal it. Those droplets that can't be collected are covered with a paste, that consists of copper powder and diluted H2SO4. Instead of this paste you can use a suspension of Ca(OH)2 and powdered sulfur in hot water. The paste (suspension) is removed after 24 hours and disposed off properly.

Please clarify for me here: Does Hg (or I2 for that matter) dissolve in MeOH? Swim has some I2 crystals he would like to react with some elemental Hg to form HgI2. Is MeOH a good medium to perform the reaction in?

The tincture bottles come in alcohol. Don't know about MeOH though.
Pardon my friend officer, He's a little slow.

Tincture = "dissolved in alcohol"

How much aluminum foil and HgI2 is required to run a hundred gram batch of p2p? I'm assuming the reaction requires 83.3g foil (1200ml MeOH). Will it then require 1g HgI2? So in theory, a single 2% 30ml tincture bottle(.6g+.474g=1.074) should suffice.
How off would one have to be on the salt/foil/p2p to fuck it up? maybe leaving unreduced shit? if there wasn't enough HgI2 wouldn't it just take longer? or would it never reach completion?
It seems like there isn't a formula or math involved, people just try different amounts and use them? I'd like the calcs. If anyone can hit me off with the math required for the calculation of the foil/salt amalgamation i'd be in your debt.

Just guessing, SWIC would say that at least 3 bottles of tincture would be needed, each with 0.5g Hg added prior.
Striving for normality!

This is also my opinion. But I am under the understanding that each 30ml 2% bottle tincture with .5 Hg in should create about 1100mg of HgI2. Using that rational seems as if 1/2 bottle or about 15ml for a MM size reaction would be fine. I have not tried yet so keep that in mind.

-demorol,
Any SOLUBLE mercury salt will do, quoting osmium and possibly labtop. Sulfate salts are insoluble. Nitrate, Halide, and others will definitely work. COnsult a general chemistry textbook, merck, etc. for sulubility guidelines of salts in aqueous solutions.
Soluble dosen't mean very soluble, either. As long as some dissolves, amalgamation goes, equilibrium shifts, amalgamation goes, yada yada yada. Transition metal salts are not very soluble. You're supposed to have at least a minimal amount of water in the al/hg depending on what variation you use. I know alcohol is present, factoring in, along with all of the other shit. Plainly, water is there. so is the water soluble mercury salt. It works.
Hope my tone isn't dry or antagonistic. I wasn't trying to be an asshole about it, just plain and simple. Good luck with any work that swid might be out to do
