cyanide
Anybody know where one can buy NaCN or KCN?
Anybody have any to sell?
Either way, let me know.

ok thanks for the idea, the only problem with some of the DIY methods:

was that they talking about crazy 1000C blasts which is somewhat agressive.

Toxicity?
A quick preliminary search failed to help me address this question: Is HCN (gas) absorbable through skin? If so, how big of a threat is this to
short-term exposure in a slightly ventilated (outdoor) area. Sorry if this has been addressed elsewhere.

HCN is lighter than air, and yes it can be absorbed through the skin. Fume hoods are much better than outdoors unless you can 100% predict the wind?
use a Rated gas mask always and have some "antidote" on hand always!

Doesn´t the body actually build up a resistance to cyanides over time? Up to astonishing high doses? Something in earlier times widely exploited by
skilled assassins?
So if anybody intends to work with cyanides a lot wouldn´t it be reasonable to get used to it - slowly and over time?

I've not heard of development of a tolerance to cyanide, however doing so for arsenic is well known.

yup me too, only ever heard of Arsenic, I`m not sure you Could Physiologically build up any resistance or coping mechanism against Cyanide anymore
than Carbon Monoxide for instance, the hemoglobin will respond the same as always.

"hemoglobin will respond the same as always. "
I agree. Most likely, he was confusing HCN with As. Amazingly, As can be consumed in amounts up to a 1g (or more!!!) if a tolerance is slowly built up
by dosing daily in small increments.

Well arsenic is still carcinogenic, so you are just killing yourself slowly.

Cyanides are toxicologically similar to CO only in the way that both bind to cytochrome c oxidase. Different cause of death, but probably no less easy
to aquire a tolerance to.

Seriously, what is with this cyanide fetish that permeates this board? I have seen more posts regarding cyanide and related chemicals than I ever
thought I'd see.

The classical qualitative test for nitrogen in an organic compound uses a sodium fusion to generate a sodium cyanide solution. The test is positive if
you detect the presence of cyanide ion via a Prussian blue color.
Cyanide is useful in processing of gold scrap and ores, I understand.
Moreover, I assume it has many uses in organic synthesis. The making of malonic acid is likely only one case.
The cyanide ion is a fundamental anion of chemistry the purchase of which is denied to us by the nanny state. That in itself is enough to justify
making it.
The single most important condition for a successful synthesis is good mixing - Nicodem

point taken. but then again, it seems that most everything is making that list nowadays...

is that the Element itself or just certain compounds that are carcinogens ?

I think most anything arsenical eventually gets metabolized enough to be bad.
I'm sure you could make a cryptand around arsenic or something, but then it's not accessible by anything, what's the point.

It makes the NIOSH list:

well I did wonder because C and H are Not always "bad" whereas Benzene is, wondered is it was specific compounds.
so it would appear that`s it`s not the compounds themselves but rather the Metabolites.
edit: double posted with you, I`ll have a read of that, Thanks

It's more a matter of whether or not the element or compound, or any of it's metabolites, bolixes (throws a monkey wrench into) the delicate
biochemical machinery of the living organism. And whether or not the organism has evolved a repair mechanism to undo the damage. And how effective
it is. And how much damage was done. And if the damage happened in a critical area. And, and, and...
Re. cyanides, thiosulfates are a cyanide antidote, yes? So maybe Rasputin survived a massive cyanide poisoning because he ate lots and lots of onions
and garlic? Which builds up thiosulfate reserves in the liver? Also chelates heavy metals.

I once worked for a lab supply house (perhaps some of you dealt with us, or even me personally; Bryant Labs, Berkeley, CA) that asked for letters of
intent for cyanide salts. That's because they had, at one point, sold a 100 g bottle of KCN to some psycho who poisoned his wife with it.
If you're just looking for a few grams to play with, get to know somebody who does silver electroplating. They use it a lot.
Please be careful. If you practice certain elementary precautions, you'll be fine. I used to shovel out 80 kg drums of NaCN. But, it's not a forgiving
material at all, and it's a terrible way to go.

There are a few theories on Rasputin, i.e. neutralized by the food, stomach condition caused by alcoholism...such theorizing is a waste of time
without unknown facts. It's funny how many stories there are of why he survived the cyanide, stated as absolute fact. Typical journalism.

Heh, I went for an interview not long ago at an electroplating firm that were using cyanide in their labs. But since I never got the job I havent got
any romantic stories to share. Pity really..

Eh, I saw a drum or two (plastic type drums) of sodium cyanide outside the plating department at work. And an empty keg, no-foolin keg labeled
"nitric acid". I mean, I know it comes in kegs, but I'd at least expect it to be a different shape. It's so funny to see it in the same keg as beer.
Don't tap that sucker!

Those nitric kegs are stainless steel. They weigh a ton. No fun to deal with, there's a big threaded bung you have to unscrew. then pump the stuff
out somehow. I'd use it for pH adjustments on a chromate dip, when I was working for a Zinc plating outfit.
