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."

...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....

That should answer all you question on HgI2...
