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 . . .

[@jhyland87]

Some of the chemistry glassware is pretty astonishing. There have been some pieces that I was very tempted to purchase, not because I had much use for them but more so because they were very unique and maybe rare (or at least rarely used, thus rarely sold), such as a _drying pistol_ (which Doug actually has a video on, linked below), a _Kipp's apparatus,_ or some _jacketed glass reaction vessels_ (which are way too expensive to purchase just because they look neat.. lol).

can acetone be used instead of MEK?

[@jhyland87]

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?

[@JonathanR1994]

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

[@ingensvidcz5390]

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?

[@ukaszjozwiak9468]

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.

They generally have to work, but not be anywhere near viable for industry. As long as it forms a detectable amount of the product, it's technically fine.

[@StreuB1]

Before you added the MEK, was what was in the flask, hydrazine hydrate......like, aqueous N2H4?

[@DougsLab]

Yep. Hydrazine hydrate, sodium carbonate, some sodium hydroxide, and sodium chloride.

[@StreuB1]

Sooooo......by dehydrating, would yield anhydrous hydrazine?

[@DougsLab]

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]

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.

[@frankroberts9320]

Astrolite, an insanely powerful binary explosive, is just a mixture of anhydrous hydrazine and ammonium nitrate. The addition of aluminum powder to zero out the oxygen balance gives Astrolite A, an even more powerful secondary explosive.

Why do this rather than forming the sulfate directly after making the hydrazine? In other words, why use the MEK and form the azine?

[@ThePaintballgun]

Just to have less solution to deal with?

Primarely to extract the hydrazine from the other impurities that are in the solution. It is faster and gives a purer product than just neutralising it and than boiling it down.

[@bcubed72]

Why do this rather than forming the sulfate directly after making the hydrazine? I'm gonna guess...less likely to kill you?

[@T2Judgment1]

+Termin Ator en.wikipedia.org/wiki/Cooling_bath#Water_and_ice_baths A bath of ice and water will maintain a temperature 0 °C since the melting point of water is 0 °C. However, adding a salt such as sodium chloride will lower the temperature through the property of melting-point depression. Although the exact temperature can be hard to control, the weight ratio of salt to ice influences the temperature: −10 °C can be achieved with a 1 to 2.5 ratio by weight of calcium chloride hexahydrate to ice. −20 °C can be achieved with a 1 to 3 ratio by weight of sodium chloride to ice.

+Minipac S Restricted? I don't know of Sulfuric Acid being restricted anywhere, I live in the US and I know the same goes for Canada and the UK. In fact, it should be one of the easiest things to obtain for the beginner chemist. Sulfuric Acid drain cleaner can easily be distilled to remove the water and other stuff. 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 KZbin 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.
