Unfortunately, in Germany the sale of H2SO4 >15% to private people has been banned as of early 2021 - because you need it for nitration of organic conpounds to produce, for example, TNT or Nitroglycerin (not that I would ever contemplate that). Before, I could get 96% on Amazon... but not anymore...
Aluminum foil too ?
❤❤❤❤❤ vvv nice ❤
Direct from wikipedia. Good editing though. I like the content you bring.
These reagent videos are great! 👌
Thanks for watching!
More chemical structure..why Habr? Benzylalcohol with DMSO Is good..or no?
In the TLC chamber wasn't a sufficient atmosphere of evaporated solvents. It simply could not form in the short time after filling the solvent. This is why the solvent front is very uneven. In addition, the starting point would be applied over far too large an area. A Pasteur pipette is unsuitable for this. The best way to do this is to use glass capillaries that you have pulled out yourself very thinly.
We conducted a qualitative analysis, not a quantitative one.
I think we have the soundtrack to "Breaking Bad II."
A friend of mine wonder if work same with Na2CO3?
You can put it that way. No need to add too much.
why dcm and water used for starting?
In acid-base extraction, dichloromethane is first used to remove impurities and then to extract the free base from the aqueous layer.
@@SafroleBlog got it :)
It’s sad the old channel got shut down. Show synth of 4-methylmethcathinone using bromine was amazing
Synthesis is available on the bbf.tax forum
ASMR: Make Dangerous chemicals with me ☺️
finally I can just buy sulfuric acid and salt instead of expensive Pool Chlorine.
Aqueous HCl dripped onto calcium chloride is much safer, cheaper and easier to clean afterwards.
Submerging in concentrated (93+) sulfuric acid requires careful tubing selection. Glass, ptfe or ldpe. It is usually sold in ldpe bottles otc. So although ptfe is nice to have it isn't required.

какой-то дизайн космический слишком..., а комбинированный холодильник такого типа не респектабельный, лучше иметь двухсекционный☝️
I see some good videos from these people on b-bad forum
Please, what concentration of Sulfuric acid {H2SO4} is suggested for this reaction?
Concentrated sulfuric acid 80%
for anyone wondering he got this video from a forum on dark web called breaking bad
Shouldn't you be using a round bottom flask suspended by a retort in the water bath? By simply placing one beaker into another the reaction flask is still in direct contact with the heat source making overheating far more likely
If I dip the steam tube in the solution, does it make a difference? Is it necessary to supply steam above the surface of the solution? Sorry for my English
I understand the question. And it's a good question. If you immerse the tube directly into the solution and pass steam through it, it will be more effective than above the solution. However, you need to monitor the steam pressure constantly, otherwise the solution can be forced back into the steam generator, for example, in the case of water hammer.
Hi, DEA clowns! Nice try.
An attempt at what? Think before you write.
Wow! Setup fit for a production lab! You’re sure ballsy for this. I believe it’s also possible to selectively oxidize primary alcohols using sulfuric acid in place of hbr. I’ve also seen people doing a free radical chlorination of benzyl alcohol then using hexamine to facilitate sn2, then hydrolized to form the carbonyl.
ill double this notion, swing big i guess
1:39 so if you place water and ice in your ice bath, it can cool more evenly with less risk of thermal shock to the Borosilicate beaker. if you wait a bit for it to cool down and you then put some table salt on your ice, the ice will get even colder, but it will melt faster. but those cold areas do act as bit of a nice seed crystal so you could just place one ice cube above the water to make larger more pure crystals, if you don't want to drop a seed crystal in from the last batch. great video.
Спасибо за коментарий. Нам это известно, пусть знают и остальные.
This could have been a short, but I am glad it wasn't.
Thanks again for sharing. Please, at 00:35, what's RM?
likely something like Receiving Molecule, or Receiving Material what ever chemistry might need HCL gas going threw it. he could be making anything really. yeah you will see this a lot a new channel will pick a click bait title to help them get views, and pretend to do a clickbait reaction to help them get views. it use to be that a channel would pretend to do this chemistry with just mixing and boiling water, but that was boring then they got to pretending with baking soda and vinegar same as science fair volcano, but that was boring too say they moved to dying the baking soda the correct color for the reaction using slight of hand and food coloring, some more skilled chemistry content creators will even find a sister reaction that looks the same but is different, but what I am excited for is in the near future the coming the deep fakes, when all video evidence and digital evidence is untrustable. with chemistry you really don't know what your looking at. even finding out what's in a beaker is a historical elaborate process of elimination or more modern spectrum analysis both requiring a physical sample.
We can get banned for what's in our glass. That's why it's called RM. Sorry for that and thanks for the comment.
Your set up makes my set up look like a joke, how did you do it on this scale and not get demonetized?
Swern oxidation ?
перекислил всё... 😂
When drying the preparation to a constant weight, an excess of hydrogen chloride evaporates. This applies only to a water-free environment (if there was water present in the starting material, the excess hydrogen chloride would negatively affect the reaction outcome).
Kindly upload an video for synthesis of ethy2 chloropropionate
Sulfur is the most common a-halogenation catalyst for organic acids; for all else, any biodiesel vid will do.
Placing it on ice is not a good idea. Just leave it to cool to room temp and then put on ice. Purer end product.
To add to this, stirring continuosly while crystallizing is necessary in the absolute majority of cases to get a purer end product. Large Crystals are a sign of decent purity, but they can actually entrap mother liquor, and make it harder to wash out impurities. There is a balance that must be achieved here, stirring to vigorously leads to too small crystals that catch a lot of mother liquor on the surface and need to be washed more, but since the surface area is large, you will lose more yield. The correct balance is often only found experimentally, but "no stirring" is almost never the right answer, even though it seems to be done a lot. In industry, you stirr by default and only try not stirring in edge cases. I could get purity of an industrial product up from 99,0 % to 99,95 % just by finding the right crystallization - and stirrer conditions without changing anything else, this absolutely matters. (Cooling down slowly was also part of the enhanced procedure, you're absolutely right about that.)
And that's how you make high quality blotter papper. hehe
Man this is the biggest experimental setup I‘ve ever seen. Do you work in a big company and could use the stuff or how did you get all of this?
I was wondering the exact same question godamn this must cost so much money
Thank you for your question. We represent the interests of the most promising community today. The equipment shown in the video is not the largest among those used in professional activities. All reactors, filtration units, chillers, rotary evaporators, and other equipment have been acquired for the purpose of demonstrating various reactions for educational purposes. We hope that the quality of the videos is sufficient for clarity and understanding of chemical reactions.
@@user-zi7fd7wc7g this guy is obviously a fed
all this guys videos are from bbgate
bbgate<3
Thank you for this video. It has very high quality, as far as I can judge.
This channel is fantastic
This video style reminds me of bbgate
You seemed ;D
@@SafroleBloglol, I think i understand your comment now 😂
Quite like the sound effects, peacefull
I used to use a pump action water sprayer, salt and sulfuric acid. You only need a splash and you only need a cup of salt. Close the lid, pump just once, everytime you want the gas aim the nozzle (that has a hose attached) at your liquid surface
There are many options for assembling a gasgen. Thank you for your advice.
@@SafroleBlog you're welcome. Anything for safety, convenience, and, essentially, what worked for me. And don't need to throw it away when the rubber piece inside quits on you. Hcl will be a pump away, just can't bottle it up for long. In a garage or semi outdoor environment this is still safe against causing corrosion. In a lab, I would only use it once to 3 times unless they've made corrosion proof models for acidic gases.
Additional question, would this method work with 1,2 diphenylethanone that might have a benzoin impurity?
Literary sources assert that bisulfite works only with ketones that have a free methyl group. However, the presence of benzoin impurities could pose a problem. That's in theory. The best way is to verify it in practice, especially if the reagent is in excess.
Ammonium chloride just because it doesn’t need to be heated like sodium chloride does?
With ammonium chloride, the formation of hydrogen chloride is simpler, faster, and cleaner. Additionally, sulfuric acid should be added in smaller quantities to avoid an excessive excess of hydrogen chloride gas.
@@SafroleBlog thanks!
Why go to the trouble of making bisulfite if your going to distill anyway.. Seems you have a few levels of redundancy here.... What am I missing?
@@matthewanderson6254 seems like his channel is just a bunch of unrelated chemistry teaching videos, not for making any one thing that I can see.
We cannot show the creation of substances here. But we can suggest paying closer attention to the show's sponsors. This is the answer to many of your questions.
High quality video! thank you, if I ever get to handle P2P I will know how to make it as pure as possible
We have several methods for its synthesis. Follow the links. Welcome
Thank you Safrole blog for your excellent video, It really expose clearly the properties of the hydrogenosulfite "adduct", the isolation of the precipitate, the washing and purification and the recovery leading to a purer keton product than the initial one. I knew the procedure, but I have never seen it was so easy. Also knowing SO2 (beware toxic) is so easy to make from dearty cheap S and that it can be readily turned into NaHSO3 and Na2SO3; I will for sure use your technique for natural and synthetised ketons and aldehyds. Kind regards, PHZ (PHILOU Zrealone from the Science and Madness forum)
Whoa! Thank you for making this detailed video. Love your work. Is it similar process using KI or NaI? Or am I thinking of something else?
Hello, what do you mean about KI or NaI? How these substance are concerned sodium bisulfite purification?
@@andybbgateon erowid they speak of a purification method of ketone or aldehyde using sodium iodide which is used instead of the bisulfite method.. I read that as well I’m trying to look for it but it has been used according to writing.
Pretty cool videos, congrats. I just have a small question, why is your TLC spot so widely spread? Wouldn't it be better to use a different solvent mix? Perhaps changing solvent ratios would improve separation and retention time, since it's not good to have sample eluting together with solvent front.
Hi, it's worth to make smaller spot. On the video, it was spread by reason of quite height concentration of the substance on the spot. In general, you are right.
