Rhodanide - 2017-05-29
More in depth in this video than I normally am as far as description goes, thanks to my buddy Frankium. He suggested that I add the reaction mechanism into the video, and I think that it turned out nicely. Go check his channel out! He's got some awesome videos that you can't miss out on.
Nicely done, interesting that sulfur can actually remove some of the hydrogen from paraffin chains. I always thought that liquid sulfur looked cool too. If you have a sulfide salt and an acid, for example, HCl and Na2S, you can make H2S much faster, adding the sulfide salt to an acid requires no heating at all. Earlier, I did so in a beaker with an open top... the smell made me regret it very quickly, fortunately I had the common sense to do so outside so that the H2S wouldn't reach dangerous concentrations. You might also be able to make thermites with CuS, just keep in mind that copper based thermites often burn explosively.
Hey, do you know what temp this needs? (Would a < 300c heating mantle work instead of fire?) also do you know if the reaction would stop with removal of heat or is it self heating once it's going?
I have no idea, I made this a while ago. Probably safe to go with a burner.
Love the videos, get a tripod and you will be on par with the other chem vids. Also if you can draw out the reactions that would be cool. Next synthesize some damamine for my sea sickness.
Dave B Dimenhydramine? That's a tricky one... as for the tripod, I'm working something out. the other problem I have is getting a good background.
Also, thanks for your support and ideas!
antiswattt3 Lol
I think is almost time for a tripod! Good job i really enjoy your videos
marcofico1 Thank you so much, hearing that just makes my day. Also, finding a tripod for a phone is gonna be tricky. I'll try to find one, though.
@Azide Where I live they are really cheap 3 € but it will improve so much your videos
You could make a make shift one out of copper wire, a cradle that the phone sits in. Dip the cradle in silicone and you protect your phone from scratches.
y dun u swirl the conical flask during the rxn??
what did you have planned for this stuff?
I AM Diablo Not much,
I AM Diablo Hey, I also wanted to say thanks for posting the video on the Nitroguanidine which included the recrystallization. I did it myself and got a beautiful product!
+Rhodanide What would be the best ratio of paraffin to sulfur, to avoid the production of carbon? Also what was the problem that you mentioned in the video?
i was just looking for an easy way to make hydrogen sulfide today, awesome video!
DeadGamer1030 Great, good luck!
Azide i need some test tubes first(i brike mine melting salts) . Also, since you like dangerous reactions, urea nitrate solution mixed with bleach is quite a dangerous combination. And so is potassium chlorate and ammonium chloride solution that you slowly add hydrochloric acid into. Both make a very nasty smelling yellow gas. So becareful. :)
DeadGamer1030 Yes, Urea and Hypochlorite salts make Hydrazine, which is very dangerous. Chlorate and acid makes chlorine dioxide, which I have included in one of my other videos.
Azide yep, though the urea nitrate reacts much faster as it make hypochlorous acid and sodium nitrate.
I always think about hydrazine when I pour bleach into an unflushed toilet. I wonder how much is produced? I tried concentrating the urine once with bleach and it gave off horrible vapours.
Hey there, I don’t know if you are still actively checking your old videos, but I would like to ask you a few questions regarding the dehydrogenation reaction by sulfur. Considering that both paraffin wax and kerosene are essentially just made of saturated aliphatic hydrocarbons, would I be able to substitute paraffin in this reaction with kerosene? What conditions would I need to change when doing so(e.g. higher temperature)? Also, I checked an old research paper on this reaction and it seems that some organic sulfides are also produced, namely carbon disulfide and thiophene. I am planning to capture the hydrogen sulfide gas using a sodium hydrogencarbonate solution. Would there be any acidic impurities from the reaction I would have to worry about when bubbling the hydrogen sulfide through NaHCO3?
Dastardly Devil I'm not sure, and haven't tried Kerosene. I never read the procedure you speak of, I got mine from PrepChem. I have no idea how it'll turn out as this was the only thing I've used H2S for. I just don't like it.
Feel free to try Kerosene, but just thinking about it, Paraffin seems easier to handle because I know exactly what's in it, as Kerosene may have additives or colorants which can decrease purity.
Did you leave the fridge door open? Ding dong lol
Cannagorilla Canna what? Lol
Rhodanide there is a sound in the video sounds like the alarm when you leave the refrigerator door open to long lol
Wind chimes are a nice touch sir...
Tate McAluney wasn't intentional lol
Tate McAluney but thanks :]
where did u get ur SOLID CHUNKS of paraffin? from candles?
TM Fan I shaved it off of a block of Paraffin baking wax. It's sold in most supermarkets as a baking additive. Sorry that I missed your comment!!
Interesting! But the discharged H2S gas seems to be dangerous for your body, was it OK? Or was the gas totally consumed in the reaction?
しん やざわ Most of it was consumed by the CuSO4, but regarding the warning at the beginning, it's not something to mess with.
Azide thank you for response and very useful information. I'm walking in chemical supplier and sometime synthesize several kgms of sulfide substances by myself, but every time I'm claimed by every workers and managers, not to spread a gas, ugly toxic danger smell! Ofcourse I always measure the H2S gas to maintain under 1ppm the nonhazardous level. But you can recognize the smell only at 20 ppb, however it were no problem if you might be in all the day. But no one understands it. Smell is equal to Danger, they think.
Why do I always concerne? It's not my hobby, it's my job!
I'm sorry to tell you my story , not related to the video. I'm Japanese ,and I'd like to try to English communication. If you have any technical topics or challenging experiment, it is supposed to be discussed together, if OK. We have pure H2S and dry and wet process and the chemically milling process.

Hahaha, reminds me of my own issues with unclamped flasks falling. Now I clamp the shit out of everything. H2S sucks a lot eh; I got a bloody nose from inhaling small amounts given off when making a sodium polysulfide solution :(
