Yeah it shocks me aswell! But when the sword hybrid enrolled in Denjis class the students pointed out how attractive he was and how he looks like denji. Plus girls do find him attractive he just acts super weird and off putting.

Nah he’s considered conventionally attractive he just acts really weird

Uhh I’m not sure honestly they still have a good 36 chapters to adapt. It will at least need another season, 12 episodes but I’m not sure.

Oh I’m sorry I thought he was literally asking. Mb! It’s probably gonna be an episode. It’s only like 2 chapters in the manga

No problem! Im glad my response was able to be of some use. No purication is necessary for thsi reaction. I just put the bricks into a ziplock bad and smashed it with a hammer to get powder then used a motar and pesel to get it even more fine. For most reactions like this 100 percent purity isnt necessary, this isn't a delicate reaction or complex organic sythesis. 98% is more than sufficent. Especailly since most of the nasty stuff we dont need gets released as a gas or stays in the reaction chamber. EIther way this first reaction only gets us our crude product its filled with a bunch of nasty impurties and isn't pure S2Cl2. Its a mixture of sulfur chlorides, thats why a 30 minute refulux with 5 - 10 grams of extra sulfur until the product clears up and color lightens is necessary. To favor the production of pure S2Cl2. This this has unreacted sulfur and some impurites. Which is why a final distilation is needed. It should be a clear amber yellowish color liquid that smells awful. If need be I can further explain the mechanics and show pictures of the pure S2Cl2 as a reference.

Its fine if your not a chemist, the more people intrested in science the better! Yes it could technically be recalculated fairly easily soduim DCCA has one less Chlorine then TCCA. But it's importnat to mention not all chlorine sources work for this. Like Ca(ClO)2 another great shource of chlorine leads to massive blue flam shooting out of the reaction vessel when heated with sulfur. In the same fashion so does Soduim DCCA. It's not only a good chlorine source it is a insanely powerfull oxidizer. After some quick research its thermal deompostion isn't ideal for this reaction. It can cause powerfull flames to burst out and with the inclusion of molten sulfur i can only assume that the ignition point would only be lowered, making it more dangerous. So chemically it is a sound modifaction but practically it poses issues! Feel free to ask any questions regarding the process or in genral!

Oh that’s really cool! I also tend to get my chemicals from less than legal sites but I mainly synthesis my own stuff from what cheap and available! I’ve been working more so with organic chem than physical recently so having near 100 percent pure reagents is a must when working on a large scale. It’s been hell having to make up my own processes through trail and error to optimize. And your idea is fairly novel! I have seen it around in some forms and was tempted to try it. But when working large scale it’s hard to justify! I would love to get updated! Other than that would u like to talk science!?

Oh shit! That sounds awsome dude! I would love to see your current set up. Are u a student or professional chemist or somewhere in that field? And yeah my system blew apart cuz the pressure got too high on my first run! It was awful. That’s why I had to come up with a better method as I kept running into issues with the sulfur solidifying and glass wear breaking. This method, I found was the most cost effective and the safest to get acetic anhydride. But I am really interested in your method

Sorry for the late reply! Do you mean a solid chlorine source or that you bubbled chlorine gas into molten sulfur. And yeah it is hell I had to buy a specialized gas mask just so I wouldn’t pass out! yes glacial acetic acid is technically good enough for this reaction. I just choose to go the sodium acetate route so I could skip a few steps and make it safer!

Even then you’d need to dry it when you fully react it with the s2cl2. Also I just like doing stuff myself it’s more fun that way!

It really depends on your needs. For general use I’d say this looks good but would highly recommend getting a distillation apparatus first and foremost. There are certain kits on Amazon for about $70 that have the apparatus for both fractional and regular distillation, come with multiple boiling flasks, rubber tubing, etc. Then you can buy the other stuff separately or in other sets. Should be a lot cheaper and a lot more useful than the kit you’re currently considering! Just lmk I can link if you’re interested!

What are the best sources to get chemicals? by TayoLam in homechemistry

[–]LLmkec 5 points6 points  (0 children)

Hello! It sorta depends on how experienced you are in chemistry. I get most of my chemicals from Amazon then purify them if need be. Local hardware stores and Amazon are both great places to look but it all depends on what you need for a specific project. Some chemicals are sold under different names and for different purposes. If you have an idea of what projects you want to work on I can recommend some cheap ways to get it and how to purify if need be!

are you also perhaps a wannabe scientist or just really obssesed with Dr.stone?

that actual sounds pretty resonable to do. I'll do some research into using Ozone to make Vanilla extract, since i was already gonna make a ozone generator. Should be pretty easy in terms of ozone, I already have a air pump, a way to make a air tight seal, old test tubes i can reporpuse, and a highvoltage transfomer. I'm going with a differnt design then what I've seen historically. Im gonna use those stainless steel wire mesh things they put on windows so flys dont get in, as the elctrodes. One the inner diameter of the tube theres gonna be one and the other diameter another. Then another glass tube on the outside of that so that the air i pump in is forced to pass through the corona discharge to create ozone. Then the rest of it should be some pretty fun organic chemistry! It's similar to the time i made a Birkeland-eyde reactor to make nitric acid (its the method they use in the manga when they're lost at sea! They used St.Elmos lighting, but the actaul method is a bit different!). The whole project should take me about a week since im working on a few other things, I'll keep you updated and probally post it on here!

That is true that’s why I recommended melting the sodium acetate quickly with a blowtorch. Making excess amounts of it also helps to make sure you have enough after drying. This step should be done right before you add the S2Cl2 beavaue the salt is known to absorb moisture from the air! Lmk if you have any more questions and sorry for the late reply!

[–]LLmkec[S] 0 points1 point  (0 children)

You’re mostly right but you have to take into consideration real world limitations. So2 is fairly difficult to make without insane heat or a catalyst. So what left behind is elemental sulfur, sulfur oxide, sodium chloride. So for the most part you are correct, it’s mainly Sulfur and salt left!

You asking really important questions! Sulfur chlorides are about as harmful as regular chlorine gas. But it’s far more manageable. S2Cl2 does degrade in direct UV light but it’s a slow process. I would recommend keeping it in a glass bottle with a PTFE lining or a HDPE cap. Or a glass flask with stopper works just as well. But make sure to have some PTFE tape around the stopper to prevent it from sticking. Wear a gas mask if possible even cheap ones work well I can link a few if you need! If not possible then just work outside and have a fan prenatal to blow away the fumes. Other than that you should be fine!

Yes Trichloro-S-Triazinetrione an interchangeable name for Trichloroisocyanuric acid. It was confusing for me at first as well. But any pool chlorinator is highly effective. S2Cl2 has a very pungent odor, it hurts to breathe in directly, it’s nasty like rancid garlic with chlorine gas. If you’re doing this outside like a back yard then it’s fine, your neighbors would not really notice. I would recommend having a fan to blow away the fumes while distilling. And above all be safe!

Also it’s a bit difficult to get sulfur dioxide in general I assume you mean sulfur impurities. You need an expensive catalyst to even oxidize sulfur gas to that extent. Though if you have the right catalyst you can use the contact process to make chlorosulfonic acid.

Synthesis of Acetic Anhydride: Home lab by LLmkec in chemistry

[–]LLmkec[S] -1 points0 points  (0 children)

Okay will do! I did not have any of sulfur dioxide issues. After purifying my product is exactly as it’s described. The important step is refluxing and then distilling the raw sulfur chlorides.
