Which is more dangerous: peroxide peroxide or flying at Mach 3.18 without a plane?

But seriously, chemistry sounds like it's a fun gig.

On the subject of horrifying peroxides, there's always TATP, which has the heartwarming nickname "Mother of Satan".

My brother, a GP, tells a story about a guy he saw a number of years ago. "Hey doc, have you heard about drinking hydrogen peroxide?" This guy was downing a tablespoon a night of the undiluted drugstore grade. 8% I think. I shudder to think of the people who decide to take it to the 'oh, @#&!' level.

Fun facts, according to Wikipedia:
"An accident involving an HTP* torpedo is believed to be the cause of the Kursk submarine disaster."

*High-test peroxide or HTP is a high (85 to 98 percent)-concentration solution of hydrogen peroxide
And the ME-163 fighter he mentions was apparently never flown by the Brits even though they snagged one, because they were terrified of it, except for a certain Capt Eric Brown who took one for a joyride. There are other terrifying tidbits:
The relative "closeness" to the pilot of some 120 litres (31.7 US gal) of the chemically active T-Stoff oxidizer [mostly HTP]...— besides the main oxidizer tank of some 1,040 litre (275 US gal) volume just behind the cockpit's rear wall, could present a serious or even fatal hazard to a pilot in a fuel-caused mishap with the Me 163B.
And the thing would regularly just set itself on fire sitting on the runway.

For many more hypergolic, exerrgonic and downright boomtastic compounds, it's worth reading Ignition free pdf download a rollicking ride through the history of rocket propellants.

I enjoyed Ignition even without a chemistry background. Now that I have a few more chem classes under my belt I should give it another read.

Concentrated peroxide has a long history in rocketry, going back to the deeply alarming Me-163 fighter of World War II.

I love his Things I Wont Work With series of blogposts so. Goddamn. Much.

Also, that dude ages with grace.

In grad school we did a lot of work on detection of TATP. So, that meant we had to synthesize small quantities. Being grad students, of course we tried to detonate it! Alas, we were never successful.

More terrifying was the cyanation reaction I had to do. Over a gram of sodium and copper cyanide in DMSO, a solvent that absorbs through the skin. In an open beaker I had to pour into another reaction vessel. And my advisor came through while I was making it, looked over my shoulder into the fume hood, and said "Smells like almonds!"

Never did that synthesis again.

Instead of being locked in a self-storage unit with two rabid wolverines, why not three? Instead of having two liters of pyridine poured down your trousers, why not three? And so on - it's a liberating thought.

Yes, liberating.

FOOF works great as a oxidizer. For an extra boost to your rocket, pair it with dimethylmercury.

One of the things I enjoyed about being the token chemist in a group of biologists was sending out the periodic "Hydrogen peroxide continues to not be a strong acid or an organic compound - please return the bottle to it's own little secondary containment vessel - the plastic beaker labeled H2O2 on the top shelf." e-mail.

I especially enjoyed finding all the ingredients for TATP in the same plastic tray in the hood and, when I went to send out the "This is a really bad idea" e-mail found that my corporate masters were blocking the link to the wikipedia page.

BungaDunga: "Capt Eric Brown who took one for a joyride."

Eric Brown was a certifiable badass, IMHO. He flew so damn many of those captured German and other aircraft. I have a DVD somewhere where he says that he always felt OK flying the planes except for the ME-163. He said something to the effect of that he always felt that the ME-163 was continuously a step or two ahead of him, and he had to do his damnedest to keep up.

I am very glad that the high school "model rocketry club" guys I knew didn't learn of the existence of FOOF while we were still in high school. Thankfully the most successful thing they ever made was the thermite they demonstrated melting trough an engine block. I think they all decided it was a little too dangerous after one guy decided he'd save a step in the preparation of something he called "white powder" — By analogy to black powder I guess. Probably some kind of phosphorus compound. — by mortar and pestling two ingredients at the same time instead of separately as called for in the instructions. His eyebrows eventually grew back.

There's a great story online somewhere which I can't find right now, about a guy working in a space launch facility in French Guyana or something, fuelling satellites with peroxide, and having diarrhea inside his protection suit because he's in a bunker half a mile from any bathroom, in 40 degree heat... I wish I could find that.

One of the Things I Won't Work With articles (I think it's the one on FOOF) links to the long, sad history of chemists trying to isolate fluorine, which includes at least two deaths, and success by Henri Mossian, who's lifespan was shortened by his work.

For those of you just following the Things I Won't Work With tag, there are at least two other similar (though even lower-volume) tags: How Not To Do It, and Things I'm Glad I Don't Do.

I particularly recommend the comments on the How Not To Do It post where he makes an open call for anecdotes of destroyed lab stuff.

...lifespan was shortened by his work.
In six words, this is why I reversed course on my path to becoming an organic chemist.

Yes, some of this also could have been due to the fact that I witnessed people mouth-pipette benzene, THF, and pyridine.

The Me-163 wikipedia entry is worth reading after this one. Fascinating!

It occurs to me that modern-day acne treatments still either tend to involve salicylic acid (skin pads used more for cleansing and treating wide areas which tend to thin skin layers and cause acne to turn over and dry out more quickly and reduce inflammation like Aspirin) or benzoyl peroxide, which traditionally was more of an ointment / pin-point approach, though it would appear Proactiv has formulated full-facial cleanses intended to help deliver benzoyl peroxide to your pores. Traditionally (to me this means "early 1990's") benzoyl peroxide was applied to individual zits.

Now, peroxides of any sort are "anti-microbial" (just as much as they are destructive to surrounding tissue) but my suspicion is that when applied topically in sufficient concentration (2.5% is common but 5%-10% is more effective), the benzoyl peroxide essentially uses the compacted oil in an infected pore ("zit") as a fuel source much more rapidly than the bacteria can (and thus shortening the overall "life-span" of the zit) and creates a slow burning reaction, burning through to the bottom of the pore, consuming the bacteria's food source that would allow it to better proliferate to the rest of the skin on eruption, as well as destroying many of the free-floating bacteria and generating a bunch of heat / entropy / free radical in the process. Getting hit by peroxide as a bacterium is bad enough, but just being the presence of an ongoing hypergolic conflagration at the molecular level probably sucks too.

In other words, oxy turns zits into mini rocket boosters that then purge themselves. Perhaps too dramatic but the visual is enjoyable.

The more quickly you attack all of the zits, the less proliferation of bacteria on the surface of your skin and the healthier and less susceptible your skin is to infection (like mowing and taking care of your lawn allows it to better compete with weeds that would blemish it).

Zits naturally "turn over" after a certain amount of time and just "decrode" into a gross scab and dry pus core typically after they themselves have consumed the plugged-up oils within a pore. A teenage camping trip involving no showers and mirrors is a fun way to learn.

The more quickly you can make them all turn over, the less opportunity for infection...peroxide!

I once had a similar experience. Turns out I'm one of the people who can't smell hydrogen cyanide. Handy info.

Between that and the time I ran bromine gas through a rotovap, it's probably just as well I switched careers.
