SublimeSparo wait until you have to learn how to use them in chemistry classes. it's not easy lol knowing electronegativity of individual atoms, and if they push or pull electrons, and then when you get into functional groups and resonance that causes certain bonds to form at different places depending on the situation, it gets really crazy. but if you're not doing a STEM degree, you might get off easy lol you're here to watch the fire, or are you thinking of getting into chem?

This more educational format with reaction mechanisms and reaction schemes is really good.

[@ihbarddx]

As a kid, I decided to esterify acrylic acid with denatured EtOH. I mixed the chemicals in a small beaker and heated it on a hotplate with a small amount of HCl as catalyst. The stuff reacted and boiled for a while. Then, in a fit of perverseness, I added a drop of MEK peroxide. Explosive polymerization took place, and, at the end, I had a foamy material, which had partially escaped the beaker and formed a plastic mushroom cloud. IIRC, that polymer was the basis of many hairsprays in that era. It was slightly water soluble, so I understood the complaints from women about their hair in humid weather. Nice piece, ChemicalForce!

"mildly explosive decomposition"

[@californium-2526]

This is a mildly(!) explosive decomposition indeed.

[@blueredbrick]

Yes mild is accurate estimation. Or benign would be a better fit. Or slow. It it great as far as peroxides can get, really. Just look at that molecule; figuratively speaking a CO2 molecule was caugt up in between the stable relationship of a phenolic ester, the monogamic bond between miss phenol and mister benzoic acid. To get that stuff going "kapoof" in a self sustained way you'll have to abuse it quite a lot: Add lots of energy in a short amount of time, and also apply catalytic conditions like having it being in contacts with: -Aluminium surface of the hotplate -The enormously porous and fresly formed surface of the burned match with so many free radicals that that surface alone would start polymerisation of many e.g. styrenes but also a peroxide bond. -Ambient light, especially light wavelengths toward the blue and more energetic. To the laymen it could (will ?) give the impression of being it dangerous. It is the opposite of dangerous compared to other radical polymerisation compounds being used for that purpose. I still like the content i guess, but DB-peroxide does more good to the society than bad as a whole. ---rant following about EU ignore please-- Im from the EU, and 'we' small business owners and private citizens and research instistutions (just before corona) got hit by a whole range of well intended burden under the umbrella name REACH, the big guys are not affected to the same degree and also have more resources. There was supposed to be some sort of feedback back and forth between Brussels and us in the case when stuff did not work as intended.. but yeah they sincerely got other stuff on their minds at the moment. (yes corona). Nevertheless, it is not a good time now to do anything related to chemistry in the EU, let alone something new/R&D. We'll get there again, but it will take more time hmz.
