Normal sodalime and borosilicate glass stops a lot of UV. For UV-Vis spectrometry in the UV range you need special quartz glass containers which doesn't absorb UV
When I was an HVAC tech I screwed up one day and got a whiff of decomposed chlorodifluoromethane, likely Phosgene. I was brazing an A/C line set and thought I had evacuated all the refrigerant out of it but I'm guessing some was trapped in the oil cause that was the worst thing I have ever dealt with. Burning eyes, nose, throat, lungs... I went to the Dr. and they said I would likely only be dealing with some persistent congestion for a while because of the low concentration (I was outside).

So this video popped up randomly in my list and I realized I hadn't watched it. Man, your video production quality has gotten so much better over the past few years. ;]
I finally found a bond energy dissociation chart that showed P/P bonds. It is 490 KJ/mole which equates to 244.1nm. So you would need a 244nm or shorter wavelength light to change the white into red phosphorus. That is hard to find!!!!!!!!!!!!!!!!!!!!!!!!!!!
Yes. I was off the mark a bit on the wavelength. And thank you for the simple statement that helped blow the cobwebs out of my memory and thought process.
Using a strong artificial UV source and a container transparent to UV would be an interesting experiment. Wonder if UVC would have a better effect than longer wavelengths.
Dissolving in Carbon disulphides doesn’t do convert at all from my personal experience, and damn you beat me on this one( I only have about 8% yield with UV lamp)
Im not sure how you could have separated the P allotropes, but if you simply added water to the chloroform/P mix you should be able to let the chloroform evaporate slowly under a protective layer of water leaving a mix of P allotropes in water.
"field test" for red is to take a measure of it on a spatula and set it on fire. You then blow it out and simultaneously fling it off of the tool and onto a hard surface. The sink works well. If your red P reignites itself upon impact, then it is still of usable quality 😎🤯
“I didn’t die...” yeah, we’re glad of that. I wonder about the level of UV you were getting from the sun. It’s Australia’s winter now. Even in Fall the UV level is really attenuated. Maybe all you needed was a more concentrated source of UV. Interesting speculation on what you did produce, however. Commonly referenced literature is not always gospel. New discoveries happen. Keep the curiosity.
The sunlight exposure was early April so Autumn for us then. And how much UV we get, well looking at UV maps of the world, I'm not in the most UV light sections but still the bottom of Australia appears to get more UV than most of America does. Combine that with the lack of tropical weather (monsoons, heavy cloud cover) and I think over the year we get more UV than most of the world
I think I read that a tiny bit of iodine catalyzes this reaction, maybe that would help this go faster? I always try to avoid using it in my lab the day before I'm gonna be making WP since I like to ampoule it and store it for a long time and I don't want it to decompose.
You should try to get yourself some "silvershield" gloves for stuff like that. They do feel like wearing plastic bags on your hands, but they're the only gloves that offer good protection against solvents like chloroform. Alternatively, you should at least use some thick rubber gloves (you can get those in supermarkets, along with sponges and cleaning products), and double-glove with thinner "examination gloves" (the ones you were using here) on top. That way, you can remove the top gloves whenever you suspect some stuff got spilled on your hands, while the thicker gloves underneath still offer decent protection. They also have a longer cuff, that protects your wrists. I'm sorry to say it, but doing what you did the way you did it was stupidly dangerous. You point it out yourself at 8:24.
seeing a comment recommending silver shield gloves from someone with piranha In their name and that profile picture, I had to click through to you're profile and was not disappointed, if you have the time and inclination you should definitely consider making more videos.
Can you use a dishwasher for your glassware? Love your videos man, awesome. Don't understand much but you're introducing chemistry to me and I love it. I'm going to night classes soon to learn more because of your channel. Thanks mate. 😀
QUESTION..........If white phos is so easy to liquify then why even put it in another solvent? I mean couldn't you have just left it in the water but heated it slightly to liquify the white phos and then put it in the sun? Have you ever thought about using a blue LED light the size of a flood light instead of the sun? The kind of light they use in grow rooms for pot plants. Or a UV light the size or output of a flood light might be good. I might try this cause i got 2 LED blue lights the size of flood lights for making halogen radicals. And I just leave it in water but heat and melt the phos at like 60 or 70C. And hopefully the red phos will fall to the bottom and collect until all the liquid yellow is all solid red.
Dissolving it does let it be completely exposed to the light, not just the surface, even if it's molten. But I do like the LED idea, you can get some real powerful LEDs these days. Wonder if anyone has worked out what the required wavelength of the transformation is?
@@ExtractionsAndIre ...........I am looking with no luck on the energy needed to change white phos to red. So far I really only just tried to google a "homolytic bond disassociation energy chart" and look for P/P bonds but they all seem to be carbon or halogen bonds on those charts i am finding. Sooner or later i will find it or just do the experiment. If i find the energy needed (wavelength) i will let you know. I did do the math for homolytic bond breaking of Cl2 and Benzyl chloride for a toluene chlorination to see if UV light was really needed AND to see if UV broke the benzyl C/Cl bond that was being made. I found that UV light DOES break the benzyl C/Cl bond that i would be trying to make. And that blue light was sufficient to homolytically break Cl/Cl bonds so UV is not needed. But that was easy cause there were so many charts. THIS IS WHAT MADE ME THINK OF USING AN LED BLUE LIGHT
@@ExtractionsAndIre ......To answer your question you need a 595nm light to break a phosphorus bond on white phosphorus so two P4 molecules can connect up to be red phosphorus. That equates to the middle range of ORANGE light. I got the bond dissociation energy of 201 Kj (Kilojoules) from a link on line and did the math to find out you need orange light. I really find that HARD TO BELIEVE that ONLY 201 Kj/mole are needed. That is VERY low energy. Which makes me wander if i am reading the paragraph wrong. PLEASE DO ME A FAVOR. I would not ask if it were more than a paragraph, but will you go to this link and make sure i am interpreting it correctly. Your probably a hundred times smarter than me in chemistry so it would really just take a minute. www.vedantu.com/question-answer/the-average-pp-bond-enthalpy-in-p4-molecule-is-a-class-12-chemistry-cbse-6052d58ad174471a869ff2ad To me they are saying it takes 201 Kj to change white phosphorus into red phosphorus. Is that what it says to you????????????????? Because it does not really say outright that it takes 201 Kj to change white into red phos but that is how l interpret it. But the low energy of ORANGE light being the answer really makes me have doubts P.S. They actually just say 201 Kj which insinuates it is for a single bond on a single molecule but i am assuming they really mean 201 Kj/mole. Keeping in mind that MOST bond dissociation energies for homolylic cleavage of a bond is between 250 and 450 Kj/MOLE so the 201 kj stated in the article must be for a whole MOLE of bonds breaking even though they did not put the word MOLE in there units I am going to do a second post about the math. So you do not have to bother reading it here. I am sure you know all the math but your subscribers might like it
Could you have gently heated the WP so it was a liquid and with stirring done the conversion in the liquid phase? Or does the RP form too solid a coating to permit this?
Perhaps the coating would be too thick. I didn't do it because of the practical problems, I just didn't want to leave my heater/stirrer on for multiple days at a time in full sunlight, the electronics wouldn't have appreciated it most likely (and its too expensive for me to break)
I have an iron-phosphorus alloy with high amounts of iron phosphide. Any idea how to extract the P from it? Acid and peroxide even over 2 months had no effect. Electrolysis yielded a yellow solution with a white-yellow precipitate. It scares me
Not trying to be a dick here I know failure sucks, however I like watching your failed experiments bc I learn so much more I think 🤔 Love your channel and keep up the good work Ps can you show the math on your Stoichiometry I’m studying chemistry at university and would like to get more exposure to the maths involved. Just picture on the calculations would be good enough as I can always pause the video.
“I’m using toluene because I have a lot of it and it’s cheap.” Jfc you lucky fuck!! I have to get toluene from lacquer thinner, do multiple warm water washes and then dry with dessicants and only ONE store anywhere locally I can find sells the correct lacquer thinner. Toluene is basically nearly entirely banned here and it’s SOOO good for dissolving Freebase… umm… amines ;)
SUGGESTION: At 250C white phosphorus turns to the red phosphorus. MAYBE......You could put the white phosphorus in a QUARTZ round bottom flask and set up for distillation so as to contain any fumes. Then suck the air out of the apparatus with a vacuum pump. And then open a port on the distillation apparatus to let in an inert gas like a noble gas or nitrogen. Then heat the white phosphorus up to 250C or a little higher. Until it turns into red phosphorus. I THINK/believe the white phosphorus boils at 280C so maybe this could work.
I know I'm fuckin 5 years late and all. But we used to have these expensive ass gloves called VITON when handling chloroform. They have cheaper ones called PVA but they're water soluble. If you're really worried about the death part of the science they might be a sound investment. :D

You can use potassium iodide at high temperatures to decompose the white phosphorus into to red
And then you also have a precursor for synthesis of Iodine.
