IBX is easily S tier, is such a clean oxidant - it + the thing you want oxidised in DMSO, stir at RT for ~ 30 mins then dilute with water, filter and extract with ether - it has helped me out of a few tight spots

"Let's put it this way: during World War II, the Germans were very interested in using it in self-igniting flamethrowers, but found it too nasty to work with. It is apparently about the most vigorous fluorinating agent known, and is much more difficult to handle than fluorine gas. That’s one of those statements you don’t get to hear very often, and it should be enough to make any sensible chemist turn around smartly and head down the hall in the other direction."

Fuming nitric acid is also a great oxidizer for rocketry, as is N2O4. ClF3 was once tried as an oxidizer, and had excellent performance, but it is of course truly evil and was not very popular.

On the subject of rocketry, hydrogen peroxide decomposed with potassium permanganate catalyst deserves an honorable mention, not as an oxidiser but as a means of driving turbopumps for main fuel/oxidizer. Used in torpedoes, missiles, and the early days of rocketry, it's still used in the Soyuz rocket (1950s to present) to generate oxygen/steam at high pressure to drive the propellant pumps. In other words, the "elephant's toothpaste" reaction has engineering uses. Hydrogen peroxide has been used as an oxidiser in rocketry but the major use is catalytic decomposition for driving turbopumps, or as a monopropellant.

Fun fact: F is such a strong oxidizer NASA experimented with it as a rocket fuel. It was used with H and liquid Li and produced the highest specific impulse of any chemical rocket. However it was never used in practice because a failure means covering large areas, or even the launch site and accompanying engineers, in F and Li which is really bad for obvious reasons.

Anyone curious about rocket fuels is required to read Ignition! by John D Clark, 1972. Here is an excerpt from a section about fluorine: It can be contained in several of the structural metals: steel, copper, aluminum, etc. because it forms, immediately, a thin, inert coating of metal fluoride which prevents further attack. But if that inert layer is scrubbed off, or melted, the results can be spectacular. For instance, if the gas is allowed to flow rapidly out of an orifice or a valve, or if it touches a spot of grease or something like that, the metal is just as likely as not to ignite and a fluorine-aluminum fire is something to see. From a distance. [...] The development of large fluorine motors was a slow process, and sometimes a spectacular one. I saw one movie of a run made by Bell Aerosystems, during which a fluorine seal failed and the metal ignited. It looked as though the motor had two nozzles at right angles, with as much flame coming from the leak as from the nozzle. The motor was destroyed and the whole test cell burned out before the operators could shut down.

Oxone really should have been on the list! It’s high molar mass, i.e. large amounts are necessary, which is a downside but it’s very useful, non-toxic and even used in pools. Who doesn’t like pools? S-tier for me! (And it can even be purified to stay as reactive but using smaller amounts)

Potassium persulfate is a really convenient source of peroxysulfuric acid. I would use this sometimes as a way to clean out dirty, clogged up fritted glass filter funnels: Add some potassium persulfate to the funnel, pour some concentrated sulfuric acid in after it, and heat it up gently with an electric hot air heat gun until the persulfate crystals dissolve in the acid. Then just let the liquid dribble through the fritted glass, and on its way it will oxidize anything stuck in there. Really easy and very effective.

6:42 I'm thinking of the 2 times when a room mate in our students' dorm cleaned the mold in the shower and the whole hallway reeked of clorine gas. Not the typical pool smell, but real clorine. First I thought I was imagining things (why the heck would I smell clorine at home?) but then I checked the hallway and the shower and was greeted with a cloud. I opened all windows (they hadn't done that in the shower) and the backyard door before I furiously send some massages in our WhatsApp group. I remember how terrified they reacted, when I told them, that they produced real clorine gas. I don't know how the did it, but I guess they mixed different cleaners.

Dupont at their Teflon plant outside of Parkersburg, WV uses 10% Fluorine Gas with 90% nitrogen in Small trailers. Gentlemen told me they actually wanted to use a higher ratio but anything higher than 10% caused issues. He went on to say if they had a trailer leak it would overwhelm the entire 50 acre site in 10 minutes. When they would need to unload the trailer it would be back up to an Overgrown Fume hood so they could connect the trailer in a sealed environment. This fume hood was actually located outside the building incase of a leak.

Should be mentioned: Concentrated perchloric acid will explode when heated. I once tried to clean a bit of expensive glassware with perchloric acid. Put the apparatus filled with the acid in a microwave. I thought I was being careful by trying 'only' 20s first. About 10s in, the whole thing exploded. An interesting oxidizer is ferrate salts. Iron really does not like being in the +6 oxidation state. It is a stronger oxidant than permanganate. A new manufacturing process has recently been developed, so it's not as expensive as it used to be. A promising industrial application is as a lethal oxidizer in water purification. Since it reduces to rust in water, a film of rust settles in the water, trapping particulates and sinking them to the bottom of the container. Since it's only iron, unlike permanganate or chlorine, it's nontoxic. A big con is that it decomposes in water, esp. acidic solutions, and it's mildly hygroscopic. Keep it dry, or keep it alkaline.

Interesting and thanks. Noticed that you mention Chlorine a couple of times. There's a sort of trick that you can do with Ferric Chloride. An older one, been around since at least the 1930s. If you heat up this material to about 70 degrees C or so, you get a sort of equilibrium that goes: Ferric Chloride Ferrous Chloride. An acquires solution of this material will work nicely to etch copper printer circuit boards. You get cuprous chloride and ferric chloride. If you pour off the liquid, while still warm, you can rinse off your board. I suppose there might be an equivalent for iodine, and I've looked, but have yet to find any. Have yet to get around and trying this last.

Oxygen is an automatic S tier, because we breathe it. So is ozone, the less stable brother of oxygen, which is also used in disinfection. So is fluorine, the oxidant of oxygen. Chlorine is S tier, as it's used for disinfection. Bromine is S tier, as it's the "scary cool liquid element". Iodine is S tier, as it's used in disinfection of wounds. So, basically, all (non-radioactive) halogens are an automatic S tier from me. Water is an S tier, because we live with it. t-Butyl hypochlorite is a B, as it's spontaneously flammable. Sodium hypochlorite is B, as it's unstable. Chlorine trifluoride is an automatic, unforgettable, S+, so is chlorine pentafluoride. Perruthenate looks cool with ruthenium(VII), so A tier. Chromyl chloride and chromyl chloride are A tier, but dimanganese heptoxide is an S tier, both as an oxidant, and as an explosive. Selenium dioxide is F, as it smells bad. Tetraacetoxylead/lead tetraacetate is a C, as it's a lead compound. DMSO is a B/C tier, because of the garlic smell if absorbed by skin. DDQ is an E tier, as it releases hydrogen cyanide. Dibenzoyl peroxide is used (2-4%) in skin care products, so an automatic A tier. 3-chloroperbenzoic acid, mCPBA, is an A tier. So is perbenzoic acid, although that melts at 40-42°C. Osmium tetroxide is a C tier, as it's toxic, smells bad, and was claimed to be used by the al-Qaeda in 2004. Though, we can't forget that it's a good oxidant and a good reagent to make 1,2-diols from alkenes.

@@That_Chemist yeah, it’s even described on some sites as “indefinitely stable if stored under proper temperatures and conditions.” So I think that’s the main reason. Regular PBA will degrade over time even with the best storage conditions. Also, it’s worth pointing out that most 3-chloroperoxybenzoic acid is actually not a pure solid. It’s sold as something like 75% 3-chloroperoxybenzoic acid by weight with 25% 3-chlorobenzoic acid and water as the remaining weight. This co-crystallizes into a mixed composition solid hydrate and that is what is sold commercially. I believe this also has a stabilizing effect. Sorta like how perchloric acid loses a lot of its more dangerous properties if diluted to 70% or lower.

Ah, organic sulfides....LOVE'em! Incidentally, I invented what I believe to be the very best perfume ever produced. It employs a skatole base scent in a mercaptan carrier. I call it, "Fecal Fantasy." I don't understand it, but I haven't received any offers from manufacturers to produce & market it.... :(

Just casually working with elemental chlorine and shitloads of HF at a semiconductor facility. It's kinda nice to walk under thin gas lines with oxygen, boron trichloride, elemental chlorine and a bunch of other stuff, not always toxic/corrosive, but definitely not very good if something goes wrong. Am i afraid of this stuff? Absolutely not, just do not punch holes in HF tanks and do not vent chlorine into cleanrooms😅 Some day someone dropped an 80l acetone barrel while carrying it around, so we suddenly had a nice friendly atmosphere in there😂 It took almost 4 hours to fully drain/evaporate and to ventilate the building

Would appreciate folks thoughts on peroxycarboxylic acids, particularly any thoughts on safe handling and avoiding common dangers. Primarily peracetic acid. I am starting to work with peracetic at 30%+ (w/w) and don't have any safety instructions from my PI (industrial research, not academic setting). I've done my own research, but would love some firsthand anecdotal accounts from some lab rats and not just vendors.

When photo masks are made, they start with a layer of chromium on quartz. Then they apply photoresist and expose it with light to make a pattern in the photoresist. Then they etch the chromium to create a pattern, which is used as a template to make chips.

Curious about danger Factor sometimes it boils like it's hydrogen peroxide when you dip a piece of metal into the solution???
