carbon tetrachloride explosive
I wonder why on earth the great Peoples Republic of Kalifornia had proscribed sales of carbon tet. Mystery solved; the stuff makes an explosive
mixture with powdered Al. It's an unstable miture so use it within 72 hours.
Cheers,

The CCl4/Al thing is not news and has been the subject of a previous thread, albeit not as justification for the CA ban.
I believe CCl4 also reacts energetically with sodium metal. I would expect potassium more so, lithium likely, alkiline earts maybe (Ca and Mg clean
turnings, say.)
Probably lit. on this.

It could be may be because it is a suspected carcinogen.

It does when it is exposed to shock, see Davis, pgs. 402 to 403 in the forum library. There are other halocarbons that react in a similar way.
Brethericks also has some literature under aluminium, then in the halocarbons entry.

I would think that carbon tet is regulated because it is regulated as Montreal Protocol substances with a high ODP are, it is hepatocarcinogenic, and
a serious groundwater threat. It has been banned from consumer goods for a long time. I last saw it in 1985.

I can't even buy it as a lab reagent without a special license I'll never be granted. So I must make my own.

The previous thread: http://www.sciencemadness.org/talk/viewthread.php?tid=5777&a...
Not just the Thai's, checking sigma-aldrich the only price listing is 12X100ML $1,015.00AU, and "sales restrictions may apply" something thats
typically reserved for strong poisons or obvious drug precursors.

I think it mainly has to do with environmental concerns... major ozone eater and polluter or something.
Not all chemicals are bad. Without chemicals such as hydrogen and oxygen, for example, there would be no way to make water, a vital ingredient in
beer.
