hst45 Posted September 11, 2006 Posted September 11, 2006 Amateur, I agree that BP is the best first step. It's pretty forgiving, safe, and is an essential skill. Just two more suggestions. 1) Small is beautiful. Scaling things small does two important things. It is less expensive to find that you've made a mistake with 10 gms. of chemicals than with a pound. Most important, if something does go catastrophically wrong you're saying "wow, that was close" instead of "Medic!" 2) Take good notes. Make it a habit to write up all your procedures as well as your formulas. You'll find this information invaluable as your skills grow. It's a great hobby, have fun and stay safe.
BigBang Posted September 11, 2006 Posted September 11, 2006 I would say save up $40 and go to the Harbor Freight that is but a few blocks away, only a 30 minute bike ride from me, so, an hour for you I would spose. I'll give you my "notes" tomorrow if you will read them this time around.
DeAdFX Posted September 12, 2006 Posted September 12, 2006 There seems to be an unusually high amount of football adveritisement this year. Good god.
DeAdFX Posted September 13, 2006 Posted September 13, 2006 Has anybody order from a site called KeteN's Chemical as seen http://www.keten.org.pl/ I stumbled upon this site a few days ago. It looks sort of questionable. I haven't contacted him/her to see if this site is legitmate or not. I guess if any Europeans need a place to order chemicals this could be a possibility... I don't know if he/she ships to the states.

Chemguy Posted September 14, 2006 Posted September 14, 2006 It is a kind of strange site, but it looks pretty usefull, hopefully they ship overseas, because it is reletively cheap 1 US dollar = about 3-3.5 zlotys, but I can't quite remember.
ULTRABUF Posted September 14, 2006 Posted September 14, 2006 Woohoo! Its my birthday today, I'm 17. I feel real important now.
ActionTekJackson Posted September 15, 2006 Posted September 15, 2006 Woohoo! Its my birthday today, I'm 17. I feel real important now. lol, well happy birthday. do anything outrageously cool?
DeAdFX Posted September 15, 2006 Posted September 15, 2006 WOOHOO I just recieved my Ascorbic acid... Its been awhile but hot damn its time to have some fun Time to find a beaker, water, and some potassium nitrate. Golden Powder here we come.
Pyrohawk Posted September 15, 2006 Posted September 15, 2006 Hey congrats ULTRA. Its good to be 17 as thats the age of the coolest person on here......me!!
Rooster Posted September 15, 2006 Author Posted September 15, 2006 I saw the thread that al93535 locked in the chemistry section about what acid that eats skin the fastest. I got kinda intrigued by this, seeing as I have spilled HCl, Sulfuric and Nitric acid on me. None of them really "eats" through the skin the way you see in movies. What acid/mix would you think be the most effective? MY LIST: Piranha fluid (Sulfuric and H2O2):A warm, strong solution of piranha fluid is supposed to eat away organic matter like knife through hot butter. This would be my pick number 1. HSO3F (fluorosulfonic acid, superacid):Hydrolyzes and releases HF and sulfuric acid. Might be a good candidate. HF:Wikipedia says that contact with the anhydrous liquid produces severe burns. HF eats tissue very well too, maybe even more effectively alone than in combination with sulfuric acid(like fluorosulfonic acid). HClO4:Strong oxidiser, may eat through tissue, never had a spill on me, so I don't know. The unstable 100% variety may fuck up skin quite badly, I believe. Before some newbie goes calling "superacids eat through everything!", know that they are only called superacids because they can protonate sulfuric acid, meaning they are a stronger acid than 100% sulfuric acid. Their properties of the acid do not apply in the definition. Anyone know anything about this? Comments? Suggestions? Mumbles?
optimus Posted September 15, 2006 Posted September 15, 2006 Here are some of my photos from the Shugborough festival of fireworks. If anyone's interested you'll have to download and unzip this file: http://creeper.250free.com/Shugborough.zip
h0lx Posted September 15, 2006 Posted September 15, 2006 HF is a gas, so it can't be an anhydrous liquid. I know 50% H2O2 burns skin pretty badly(from own experience, spilled some on my arm and ran to toilet screaming, makes skin bright white too) Phenol in nasty too on hands, after a brief contact, I'll always wear gloves while handling/weighing it...
Ozzy Posted September 15, 2006 Posted September 15, 2006 The worst i ever had was some 50% H2O2 also i got some as a sample and the fucknig buring doesnt go away but it doesnt eat threw jeans or shirts or chairs like H2SO4
DeAdFX Posted September 15, 2006 Posted September 15, 2006 I would assume a strongly acidic/oxidizing acid or acid combination would be your best bet. Some acids that come to mind are Aqua Regia(HNO3/HCl), Sulfuric acid and Mn2O7, and sulfuric acid and chromic acid. HF's boiling point is pretty close to room temperature. If it is every snowing and you don't feel like you need your arm anymore then I guess you could give the FHSO3 a g.
Mumbles Posted September 15, 2006 Posted September 15, 2006 Believe it or not, gases arn't gases forever. Ever hear of liquid nitrogen? Liquid nitrogen is anhydous nitrogen liquid. You could compress or cool the HF to make an anhydrous gas. Anyway I agree with DeadFX on this one. What you want for say material/flesh destruction is not so much an acid, but more an oxidising agent. It will be much faster. One of the best bets I would say would be the superacid HF/SbF5. It's the strongest one to my knowledge. It has excellent oxidising capabilities. Also, there is a high percentage of protonated H+. As some of you know HF is considered a weak acid(low protonation). The SbF5 provides F- ions, which basically completely protonates the HF due to equilibrium and such. This makes it exponentially more corrosive. Also in addition to burning through flesh, you're also going to die due to all the calcium ions being removed from your blood, thus stopping all muscle function, including the heart. If that somehow doesn't get you, the Sb poisoning will. Molten NaOH would do some damage too. Perhaps SO3. If you really want some burnage, mix a little capsacin into the acid.
ULTRABUF Posted September 15, 2006 Posted September 15, 2006 Thanks guys. No I didn't do anything outrageously cool. I think the highlight of my day was the bus ride out to the college for auto class. There's this one "special" kid that goes out there with us, and he had like a your momma joke battle with this other kid. His were actually funnier than the other kids' too. It was so hilarious my jaws were aching from laughing. Hopefully some birthday money will find its way to my mailbox soon so I can buy stuff.
Rogue Chemist Posted September 15, 2006 Posted September 15, 2006 In relavence to the acid stuff: Several chemistry proffs of mine have told me nitration acids will burn to the bone, I am doubtfull about this however. HSO3F/(Sb/As)F5 are quite (a couple of the most)powerful, their acididty may or may not determine their burning of flesh ability however. I got a couple drops of aqua regia on my wrist, dissolved a hair, but it was washed off too fast to feel anything. Perchloric(70%) hurts bad, but i did not notice any damage when it was washed off. More painful than any of the common strong acids which don't really hurt. glacial acetic hurts in the same way as perchloric. Same with acetic anhydride. Mn2O7 in H2SO4 I got a smear on my thumb once, managed to wash it off about 10s later. No pain no damage, weird. It took so long to get off as it did not feel 'wet' to me, I only noticed it when I saw it. MnO3F in the liquid state I imagine would be a nasty. No experiance here as I don't fancy the use of fluorides in acidic environments. Oh almost forgot, washing P2O5 dust off your hand hurts pretty bad from the heat of hydration and the phosphoric produced.
Mumbles Posted September 15, 2006 Posted September 15, 2006 I would think just having the P2O5 on there would hurt. You know, the whole water being sucked out of your skin thing. With the nitration acid burning to the bone I believe it. But you'd have to pretty much dip your arm in a vat of the acid for a few hours I would imagine. If it doesn't burn your flesh off, grab a lighter and you'll have a cool party trick.
Ozzy Posted September 16, 2006 Posted September 16, 2006 Just for shits and giggles http://video.google.com/videoplay?docid=-4...371556539&hl=en
Rogue Chemist Posted September 16, 2006 Posted September 16, 2006 It really was not on there long, and it was a dusting. The first thing I thought of with it on there was the sucking of water, so I went to the tap fast. Pain came from a single drop of water hitting the dust before the main spray hit. I should get some of that for myself, I imagine I can do some bartering with a professor to get some. Its worked for other things.
maximusg Posted September 16, 2006 Posted September 16, 2006 mmm, I'v had Mn2O7/H2SO4 drip onto my skin as well. I also didnt notice until i saw the green stain on my wrist... i went to the tap and rinsed for several minutes to clean it... didnt feel anything. Strange, as the same solution would cause other organic material to crackle and flame, but not my skin. Perhaps the oils in the skin acted as a protective barrier of some sort.
DeAdFX Posted September 16, 2006 Posted September 16, 2006 WOOHOO I just recieved my Ascorbic acid... Its been awhile but hot damn its time to have some fun Time to find a beaker, water, and some potassium nitrate. Golden Powder here we come. An update on the golden powder situation. This golden powder(gp) makes a great lift. Gp doesn't use sulfur so their are a lot less compatibility issues. I Used h0lx's 2 minute mine tutorial here http://www.apcforum.net/forums/index.php?showtopic=566 to test out the gp. I used a mix of potassium chlorate/benzoic acid/titanium as a star material. My first trail failed as I had to much tissue around the stars. The second trail was more of a sucess, however the stars exploded after being launched.
TheSidewinder Posted September 18, 2006 Posted September 18, 2006 Since this *IS* the random thread..... I just got back home from vacaion. One of the people I visited worked at Rocky Flats in Denver for 20+ years, and now works at Kirtland AFB in Albuquerque, for a private contracting firm and does basically the same thing: He decommissions nuclear weapons, the test equipment for them, and various other NASTY things used in the nuclear industry. We got to talking about strong corrosives/acids. He told me there's NOTHING quite as vile as..... get this.... Plutonium Tetrafluoride. (PuF4). Naturally, none of us are likely to encounter this shit anytime in our lives, but he says he has to deal with it on a somewhat regular basis. I can't imagine the nightmare THAT would be to contain, should an "incident" occur. Yeesh.... gives me the willies just thinking about it. M
Rooster Posted September 20, 2006 Author Posted September 20, 2006 Come to think about it, a nice combo would be anhydrous CrO3 mixed in with/dissolved in Oleum. Would do well in both oxidising and acidic abilities.
