Hi bro. Can you help me for making polyéthylène glycol (PEG) ?
I have tried keeping nco oh ratio one , but my precipitate is not hard, i tired of this,i am also using chain extender, please somebody help me
l don't understand 4-ap
Can you explane how the reaction goes?
how did you make the saturated NaCl solution, it hydrolysed the ester in my reaction.
KarpsChem stole your video
Cool
Great video, thanks!👋 If you need polyurethane resin epoxy resin precision flow meter, metering pump, please feel free to consult CIXIFM Winny,thanks~~🤪
How about sodium/potassium? What will happen?
Would it be food save to drink it when using ethanol and re-destill it instead of DCM carriers?
What happens if you mix pure hydrogen peroxide with chlorine trifluoride?
Wonderfully done. Can you suggest a paper for reference where I can see details on concentration, time, RPM, etc.?
Concentration 1:1 polyol iso cyanate
Time 30 min
"stir gently", by putting the RPM on max.
rocket stuff may have been in its infancy in ww2 But what possessed a scientist to use this as an ingredient for the fuel for an me163
It's the oxidizer in the Komet, the the fuel is alcohol. What makes it attractive is the liquid decomposition into several hundred times its volume of oxygen gas - making it a powerful rocket fuel. The small maneuvering motors on the Apollo spacecraft used concentrated hydrogen peroxide that was introduced to a catalyst in the thrust chamber and decomposed without any other chemicals. No need for complex moving parts, cryogenic storage, or an ignition system.
@@josephastier7421 The Russians still use hydrogen peroxide on their manned Soyuz spacecraft. Works well.
Help things burn like oxygen gas because it is oxygen gas
And it breaks down into oxygen and water
Mix oleum with pure H2O2.. then drop something organic into the mix.
Amazing how many people don't realize how dangerous it is Working with it in it's pure form gave me much more respect as to how it should be handled. Many people don't understand how diluted it has to be in order to be sold to the public.
The stuff I get at the grocery store is 3%
Yea the most common one is 3% and the most concentrated i could find online was 12%
@@Viciously79 I bought the 12%, on the bottle it’s got a website where you can buy 32%.
90% h2o2 vs scraped knee?
@@13orrax h202 wins, you would no longer have a knee.
can you explain in detail the preparation of concentrated hydrogen peroxide
You can buy 3% at the grocery store. If you want higher concentrations and not kill yourself then you need to get a degree in chemistry. Or two.
what type of polymerization method is this?
The smell of that reacting triethylamine...gross
1:08 _Dink!_ _Bck-lcklcklll_ “Uh oh.”
Freaking Awesome ! So dangerous but worth it
Why isn't this used in jet engines
TOO MUCH POWER
As a suggestion for the next video, please add more time for the appearance of the subtitles. They appeared very fast.
Can someone explain the mechanism of this reaction ?
it's called grignard reaction.
@@NightLightnight why add Co3 wth ether in the vessel?
@@Robinrobin1610 wash out remaining acid
@@NightLightnight what about NaCL?
@@Robinrobin1610 because salt solution has high affinity towards water, it pulls water from organic layer, the technique is called "salting out"
never heard of that method of concentrating h2o2
What happens if we add cyclohexane in the reaction flask instead ?
How to dope with it fluorescent powders?
A wee bit mad scientist, but helpful. Thanks man.
Is ethanol highly explosive with liquid hydrogen peroxide? with detonator
When mixed it makes an ethanol oxide so yes but not as potent as other fuel sources
Would like to watch but video no longer plays. Freezes a few seconds in
other than recrystilisation is there another method of purification that could have been used ?
Can we make polyol in home research... Only POLYOL i mean
i think its just some clever distilling, but watch out if u breathe in fumes - CAN KILL U!!!
Heavy lacking on instruction
Nie czaje tego, kiedy oddzielić żółtka?
Amazing work and can you upload preparation of DOP ( dioctyl phlate ) chemical
Hey . Can u guide me on how to synthesise thermoplastic polyurethane ?? With polyol , MDI and diol?
Bro that's a deep technology

Elephant toothpaste brought me here. Next viral video on youtube... High test hydrogen peroxide in elephant toothpaste - guaranteed. As an engineer, couldn't stop watching this video. Lost interest in elephant toothpaste and gained a curiosity for chemistry. Great, another thing to obsess over.
How much add the charcole
I think I’ll stay with my 50% :)
Method 1) Add 100nl acetic in round bottom flask 2) Add 50ml aniline into the flask slowly 3) Turn the stirrer on and start circulating the water into the condenser 4) Start to heat the oil bath 5) Measure the temp to keep oil bath at 110 degree C 6) Heat and reflux for about 2 hours then turn of the heat 7) Pour directly into ice water 8) If chunks gather at the bottom use a stirrer to break the chunks 9) Then filter the contents 10) Then recrystalize then crude acetanilide 11) Add the crudes into a 500ml breaker with 200ml distilled water 12) Add 5 spoons of ethanol then heat the solution with the stirrer on 13) Heat until it comes solution gets clear, when it have all dissolved, just cool it down and then filter it 14) The contents may contain some impurities - if so recrystalize again until pure acetanilide is produced
Thanku
asmr vibes
lovely crystals of acetanilide i loved it
How is that an ice bath? The flask barely fits in that tiny amount of water and it's on a still hot hotplate, and there's no ice lmao
Can anyone tell me the scientific name of the thermometer used? I want one like that
1:32 me and the boys going super sayin and killing frieza
