HAZMAT called at UCSD


http://www.nbcsandiego.com/news/local/Hazmat-Crews-Respondin...

No injuries were reported. There aren't any details as to what chemicals were mixed, but I have an excellent feeling this is overblown. What do you think?

You know those guys at the fire department were just itching to bring out the big guns. They freak out this same way anytime a couple of grams of picric acid are found at a university.

That's my guess too: picric acid or maybe some TNT.

Didn't picric acid use to be made in school labs to make a yellow dye?

Another link from Reddit:

I've included links to this and the TMS azide explosion that Cheddite Cheese talked about.

That was my immediate thought, but it said they mixed two chemicals together. I heard about a bottle of mixed acetone and nitric acid exploded quite violently at night in a lab once; maybe it's something along those lines.

It was silver nitrate and ethanol. Isn't that mixture used in electrophilic substitutions, if I'm not mistaken?

Resulting in probable in situ formation of sensitive Ag fulminate...
CH3-CH2OH + AgNO3 -unequilibrated-> AgO-N=C + CO2 + H2O
A few mg into a glass recipient with flamable ethanol is quite a treat if spontaneous detonation occurs! A bit like an activated grenade...Maybe was Bruno Mars involved? ... "I got a grenade for you..." Joke :):D;)
