Hg(CNO)2 synth question
(reaction performed outside at 45 degrees F yesterday)
1st beaker is 5g Hg dripped into 40ml 70% HNO3
beautiful reaction, some NO2 gas evolution
i went running for an hour, upon return
rich dark blue green layer on bottom, clear layer on top
2nd beaker with 55ml CH3CH2OH was prepared
dripped first beaker into ethanol beaker with swirling
...nothing happened...
a few minutes of gentle heating and tiny bubbles started
this developed into a huge plume of white stinky vapor
this part frightened me
several hours later reaction was over
temperature down to about 35 degrees outside
poured contents onto wet filter paper
wash with water, then ethanol, then water again
drying filtrate over night yields slightly clumpy slightly off white material.
1) under magnifying glass I can see no distinct crystals.
2) under different lights I do see tiny glints of reflection.
3) the pics on powerlabs seem to show tiny crystals
4) the pics on image search seem to show tiny little crystals
about five sand size particles of this product detonates with hardly any provocation
please,
1) did the cold outside mess me up?
2) are there suppose to be visible crystals?
3) does the product seem correct?
4) have i synthesized some random nitrate slop?

Sounds like a success to me.that white cloud with the smell similar to freshly cut apples is a good indication that things are going as they should
be. The product i get is a beige colour crystalline substance. you should try looking at it under a microscope as this will reveal the crystalline
features much more clearly.

If you want large crystals- (And that might NOT be a good idea!)
Dissolve the fulminate in strong ammonia, filter the solution and while gently and continuously stirring, SLOWLY neutralize the ammonia with a drip of
glacial acetic acid. You'll see crystals growing in the liquid as the ammonia is taken up by reacting with the acid. The slower the addition, the
larger the crystals you'll get. When you've added nearly enough acid to neutralize all the ammonia, drop a ph cube or test paper into the beaker and
slowly continue just until it indicates neutral. Filter the crystals out and wash with distilled water several times, then do a final wash with
alcohol.
Store the crystals under water- NOT dry. And know that even wet fulminate can be detonated by dry fulminate.
Rapopart’s Rules for critical commentary:
1. Attempt to re-express your target’s position so clearly, vividly and fairly that your target says: “Thanks, I wish I’d thought of putting it
that way.”
2. List any points of agreement (especially if they are not matters of general or widespread agreement).
3. Mention anything you have learned from your target.
4. Only then are you permitted to say so much as a word of rebuttal or criticism.

Umm if it detonate easily then it should be correct since mercury fulminate is famous for that, and as for neon pulse, smelling the detonation
product, the smoke, to decide whether if it is mercury fulminate might not be a good idea.

Geez, give me some credit! i think i have been misunderstood there.i don't mean to directly sniff the fumes of the detonation- those fumes are pretty
toxic. i meant the smell that lingers during the fuming off period of the synthesis, kind of smells like a fruity smell similar to cut apples. Also
not a good idea to intentionally inhale but you certainly can smell it in the air.

The fruitiness is acetaldehyde ─ oxidation of ethanol . . .

recrystallize!!
I should have thought of that.
Sam Barrows recrystallized too.
Yes, vary the crystal size... Interesting...
Is acetaldehyde the prominent white vapor that occurs during the second mix?
I am so slow with learning about compounds. It took me about two months to satisfy myself with copper sulfate. This compound is going have me
experimenting for a very long time.
