When I was a kid, I got a chemistry set for Christmas. Enjoyed watching reactions and what I could make and use. Junior high school chemistry class was a blast since we got to use chemicals and apparatus that I could not get to use otherwise. Lots of fun, and it was all a breeze for me since I already had an early start on the subject. When I got to high school, the math/molar values that went along with it took all the fun out of it for me. Really took my wind out of my sails. But thanks for these viddys, and keep them up! Enjoy watching the methods, the equations, and the reactions you do, Doug. Nile Red is a lot of fun too, always seem to enjoy your viddys a bit more - tho . . .

Is there actually a chance that some base had made it into the product and actually created freebase hydrazine? The powder was well dried so there should not be any moisture present but maybe it picked some over time?

26:25 probably it will works better to reuse the solution to take off the sulphate completely from roundbottom flask, and then flush twice (using smaller volume) with ice cold watter whole precipitate. I followed similar procedure to obtain hydrazine sulphate maybe 15 years ago. But I used some kind of bone glue as catalyst, instead of gelatin and miss the hydrazone reaction. Just add the sulfuric acid directly to water-hydrazine solution (more preciselly hydrazine hydrate solution). After filter off the impurities that comes from glue from hot solution, I colled down the whole volume. Of course the yeld was probably less than yours but the product was pure enought to azide preparation.

Yes, but it's not practical. You could do it by distillation, but the concentration is so low in that solution that it would take several large-scale distillations followed by chemical desiccation. To make anhydrous hydrazine, it would be far easier to make the sulfate first, then mix it with an excess of a strong base like sodium hydroxide in a copper-jacketed reactor and distill the hydrazine off, followed by a finishing pass over a strong chemical desiccant like refluxing it over calcium oxide. Also, hydrazine is distilled in copper or silver vessels because the hot anhydrous stuff attacks glass. The apparatus must first be maintained under dry inert gas because these metals and their oxides catalytically oxidize hydrazine easily in the presence of oxygen and any leaks would cause an explosion. Remember - hydrazine is used as a monopropellant. It's dangerous stuff!
@StreuB1

Hydrazine is such an amazing propellant; it sucks how unbelievably poisonous it is. :-( I am into experimental rocketry and its one of the god propellants that no amateur can ever really use. Its always fun to think about it though. I view RFNA and NTO as less dangerous just because I know their mechanism of danger. Hydrazine....its not immediately apparent AND its clear as water. Also why I refuse to mess with high test peroxide; nope nope nope lots and lots of nope. What would the best direct reaction to efficiently produce nitrogen tetroxide be in your mind? I have been researching this a lot lately. Skipping nitric acid and going right to NTO distillation from base chemicals. Sulfuric acid, copper, potassium nitrate and HCL IIRC NurdRage did which seemed plausible. So far, Chem Player is the only major YT channel to go directly after NTO in an experiment.....and it was fantastic. Hint Hint :-)
@DougsLab
8 жыл бұрын
Copper and nitric acid are convenient, especially if the copper II nitrate formed in the initial reaction is then heated to dryness where it will decompose into more NTO, for a net equation of: 2 HNO3 + Cu --> CuO + H2O + 2 NO2 The CuO is easily reduced back to the metal by heating it under hydrogen (easy with HCl + Al or something equivalent) which will leave behind reactive powdered copper ready for use in the first step. However, I understand the need for a more "quick-and-dirty" prep for making larger amounts rapidly from OTC sources. I will sleep on this one and get back to you, although I think it would be possible to set up a tabletop production plant which starts with ammonia and uses an air bubbler to push it through a platinum wire screen as a catalyst, which would self-heat. This would be mixed with more air and cooled to oxidize it to NTO, which would then be condensed. You could make several liters per day with something like this and it would be very cheap to run. The initial investment in platinum wire would be a little expensive though.

Another form is car battery acid, which can be purchased from some automotive stores for refilling batteries. That's about 35% and can be easily concentrated with little to no impurities. It can be made by various methods if necessary, just search KZread for "making Sulfuric Acid". I believe those methods are not the most efficient though. It can be made from Sulfur and Water if you have a catalyst of some sort. If only it was as easy to make as Nitric acid. Nitric acid is ridiculously easy to made. Take air, zap it with a 10kV or higher voltage electric arc, and bubble the resulting brown colored air fumes into water. After running for several days, you'l have at least 10% Nitric if done right. It can be further distilled.

You comment a lot about chemical safety, such as when you make ketene (which is so unstable in humid atmosphere you would be hard put to breathe any), but make no comment about hydrazine. Hydrazine is insanely toxic, being able to penetrate through skin in addition to the lungs. (There are cases of people dying later from one drop falling on skin.) "Allowed" exposure, one time only, is in the range of 2 parts per million in air.

Junior high school chemistry class was a blast since we got to use chemicals and apparatus that I could not get to use otherwise. Lots of fun, and it was all a breeze for me since I already had an early start on the subject. When I got to high school, the math/molar values that went along with it took all the fun out of it for me. Really took my wind out of my sails. But thanks for these viddys, and keep them up! Enjoy watching the methods, the equations, and the reactions you do, Doug. Nile Red is a lot of fun too, always seem to enjoy your viddys a bit more - tho . . .

Secondly, a salt water bath cooled with a dry ice pack, instead of making multiple trips to the freezer...or wait till winter and perform the experiment outside, packing the beaker with snow.

Hey Doug. I haven't found much info on making copper oxysulfate, have you come across it?
Nice sir & thanks
So I have prepared the salt with this method, but after some time I wanted to use it in a synthesis. But when I opened the bottle, there was a faint ammonia-like smell coming from the crystaline powder. Is there actually a chance that some base had made it into the product and actually created freebase hydrazine? The powder was well dried so there should not be any moisture present but maybe it picked some over time?
found a brand of hypochlorite in my country claiming to be 35% hypochlorite. what do you think, is it actually 35% NaClO or did they actually mean 35% active chlorine by weight?
If you use large amounts of cheap chemicals it may sometimes also make you use large amounts of non-cheap chemicals.
The aqueous layer is probably saturated with MEK. You could probably extract it with more MEK since it should just layer out... not that it would probably increase your yield very much.
I love the thought of making rocket fuel. Is there a possibility that you could show the combustion of hydrazine? Preferably, you could with oxidizer. I know that there is a great risk of explosion. But again, I would love to see you do it.

Since acetone is a ketone you can add a solution of acetone an MEK right?

26:25 probably it will works better to reuse the solution to take off the sulphate completely from roundbottom flask, and then flush twice (using smaller volume) with ice cold watter whole precipitate. I followed similar procedure to obtain hydrazine sulphate maybe 15 years ago. But I used some kind of bone glue as catalyst, instead of gelatin and miss the hydrazone reaction. Just add the sulfuric acid directly to water-hydrazine solution (more preciselly hydrazine hydrate solution). After filter off the impurities that comes from glue from hot solution, I colled down the whole volume. Of course the yeld was probably less than yours but the product was pure enought to azide preparation.
can acetone be used instead of MEK?
It would have been nice to see a clean recrystallisation, or more washing, but it's a nice video, very nice lab!

Since MEK is now pretty difficult to get (You can get the _MEK substitute,_ which is _ethyl acetate_ which isn't a ketone), one could do this same reaction by substituting the MEK with a stoichiometric equivalent of acetone, correct?

Yes, but it's not practical. You could do it by distillation, but the concentration is so low in that solution that it would take several large-scale distillations followed by chemical desiccation. To make anhydrous hydrazine, it would be far easier to make the sulfate first, then mix it with an excess of a strong base like sodium hydroxide in a copper-jacketed reactor and distill the hydrazine off, followed by a finishing pass over a strong chemical desiccant like refluxing it over calcium oxide. Also, hydrazine is distilled in copper or silver vessels because the hot anhydrous stuff attacks glass. The apparatus must first be maintained under dry inert gas because these metals and their oxides catalytically oxidize hydrazine easily in the presence of oxygen and any leaks would cause an explosion. Remember - hydrazine is used as a monopropellant. It's dangerous stuff!
@StreuB1

Hydrazine is such an amazing propellant; it sucks how unbelievably poisonous it is. :-( I am into experimental rocketry and its one of the god propellants that no amateur can ever really use. Its always fun to think about it though. I view RFNA and NTO as less dangerous just because I know their mechanism of danger. Hydrazine....its not immediately apparent AND its clear as water. Also why I refuse to mess with high test peroxide; nope nope nope lots and lots of nope. What would the best direct reaction to efficiently produce nitrogen tetroxide be in your mind? I have been researching this a lot lately. Skipping nitric acid and going right to NTO distillation from base chemicals. Sulfuric acid, copper, potassium nitrate and HCL IIRC NurdRage did which seemed plausible. So far, Chem Player is the only major YT channel to go directly after NTO in an experiment.....and it was fantastic. Hint Hint :-)
@DougsLab
8 жыл бұрын
Copper and nitric acid are convenient, especially if the copper II nitrate formed in the initial reaction is then heated to dryness where it will decompose into more NTO, for a net equation of: 2 HNO3 + Cu --> CuO + H2O + 2 NO2 The CuO is easily reduced back to the metal by heating it under hydrogen (easy with HCl + Al or something equivalent) which will leave behind reactive powdered copper ready for use in the first step. However, I understand the need for a more "quick-and-dirty" prep for making larger amounts rapidly from OTC sources. I will sleep on this one and get back to you, although I think it would be possible to set up a tabletop production plant which starts with ammonia and uses an air bubbler to push it through a platinum wire screen as a catalyst, which would self-heat. This would be mixed with more air and cooled to oxidize it to NTO, which would then be condensed. You could make several liters per day with something like this and it would be very cheap to run. The initial investment in platinum wire would be a little expensive though.

Another form is car battery acid, which can be purchased from some automotive stores for refilling batteries. That's about 35% and can be easily concentrated with little to no impurities. It can be made by various methods if necessary, just search KZread for "making Sulfuric Acid". I believe those methods are not the most efficient though. It can be made from Sulfur and Water if you have a catalyst of some sort. If only it was as easy to make as Nitric acid. Nitric acid is ridiculously easy to made.

8:23 you mean fortunately, right? ;) Calm down, comments section.I'm being facetious.

+Doug's Lab Well to be fair, the numbers transferred between the two teams didn't have friggin' units on them. Oy vey.

Azide N3 That's true; and if goal is to perform a specific reaction in an efficient and cost effective manner, purchasing commercially produced chemicals will almost always be the best route. However, having watched Doug's videos for a while now, it appears his approach on this channel is geared more towards the production of chemicals for the sake of performing the reactions.

John Ratko Yes, I agree.
oh, c'mon. you're at least 3rd youtuber doing this. Chemplayer and another weird guy make hydrazine from urea before. Not a long time ago, however.

+Martin of Gliwice Ugh, I know. I was already halfway done filming this when ChemPlayer uploaded his! Luckily I think I have used a different method than any of the other videos, even if the yield is a bit low.

+Chem Player Honestly though, I don't think it's any less useful to make videos about things other channels have done. The apparatus, lab technique, and scale is all a little different. Everyone knows the surest synthesis pathway is one with multiple references. I have things on my list to do that you guys ave already covered, but I need them as intermediates for other stuff, and I figured I'd film anyway. If anything it says, "I used this method and it worked for me too."
I hate to be critical but I don't know how in God's name you use that lab ZAP crap oh it's terrible I would rather get used Corning Pyrex beakers on EBay
