Extractions&Ire - 2016-02-10
I must be doing something wrong... but what is it guys? Something super obvious or subtle? I'm all out of ideas.
"that's my glove, my hand doesn't look like that"
I use Ca(OH)2 react with CuH(NT)3 and heat and filter get Ca(NT)2 and mix with NH4CO3 to get NH4NT
4:56 RIP chemplayer <3 both of your vids.
You can't use bicarbonate. pH not high enough. Use sodium carbonate to cyclize guanyl azide to 5-aminotetrazole
is it because u use HCl??
it react with sodium Nitrite to form Nitrosyl chloride??
RIP tetrazoles you will be missed
sob
That part with the ph paper killed me xD
About that NaNO2 problem: couldn't you just heat sodium NITRATE until you have NITRITE? I heard something about that working.
+Azide N3 Yeah that's what I've found, there is the odd method but they're all so labour intensive. I also only have KNO3.
I have tried making some KNO2 from KNO3 + Sugar mixes that are very rich in sugar, with signs of success. It's not really worth it though (God the carbon... at least it smells like pavlova the whole time) but I wanted to get it worked to kind of complete the OTCness of this series. Because even my KNO3 was bought as a fertilizer, so if I make the nitrites then everything becomes OTC or a derivation of.
@Extractions&Ire I could ship you some lol
Dude theres another method in some SM thread to produce Sodium Nitrite that might help you. It involves heating Sodium Nitrate with Calcium Sulfamate, the acid of which you can find as 'descaler and grout cleaner'. Since the Sulfamic acid is only like 15 bucks a kilo, it might be an OTC option.
Another cool thing is using Prague Powder, its a curing salt that its possible to extract Sodium Nitrite from (using ethanol or whatever). The stuff is available in some bulk food stores (not Costco).
Problem is I don't have sodium nitrate either. I've made a small amount of potassium nitrite but it's very hygoscopic the ziplock bag of it is now just full of water which is not impossible to work around of course but it is annoying. Also the conversion temps for K are probably different than for Na.
I am hopefully getting some Ca(NO3)2 soon so i'll be able to double displace my way to some NaNO3 so maybe i'll revisit this then. In the mean time I have some more NaNO2 in the mail :D :D
@Extractions&Ire I was gonna say, I could send you some, I've got a lot haha
NaNO2 that is
I have no idea with tetrazoles but most of diazotization reaction occurs at low temperature (about 2~8'C) so why don't you try dripping process in icebath?
+LaFFle Yeah usually they need to run cold and with dilute acid, but apparently this one needs conc. acid and room temp. Just depends on the ease of adding that N=O group I guess
Is this the origin story of going from loving yellow chemistry to hating it???
Birkeland–Eyde process has always seemed awesome to me. You should make a setup. I should make a setup. We should all make setups so long as we all have the same interest of the ol big E. Or I suppose if you need to purify gold frequently aswell.
I know this would make for an awesome video so long as high voltage doesnt spook you too badly (or maybe even if it does) but if you do this right it'll be an epic longterm investment sure to pay off loads and loads.
Wish I could help but I couldn't even get nitroglycerin to explode hahah smacked the shit out of it and nothin... Keep trying!
Maybe your product decomposed before u got to wacking it. Or you managed to not make it at all
What if that black dye has been secretly ruining everything the whole time
Could you attempt a organic extraction with ether or dcm? The tetrazole may be soluble but the salts wouldn’t be. Might be worth a try.
+hunterboyvids That's a good thought. But if it's in there it should have crystallised out, but i'll think about using DCM
why don't you make your own sodium nitrite ? it's easy peesy..just Sodium Nitrate, sodium hydroxide and sulfur, grind them all up together and ignite, it reacts like hell, a small fire works eruption, leaving you with a red hot steel bowl , the liquid will solidify as it cools, leaving you with sodium nitrite and sodium sulfate. just add water, heat to dissolve, allow to cool recrystallize, the sulfate will crystallize out first, dump those solids, then evap your left over liquid, high grade sodium nitrite, no worries, done it plenty of times. your welcome...
even a fail its still a nice vid you can at least narate some jokes lol but sorry i have no idea
Have you tried to let it sit for awhile and then pour it into another beaker? Remember how the successful batch worked out with the saturated solution crystallizing out.
Are you still using that rock you found in the garden as a source of calcium carbonate? You should consider using a purer reagent, maybe it isn't critical but you will eliminate some variables. All that time outside it could have accumulated impurities or maybe it wasn't 100% calcium in the first place. I'm wondering about some magnesium contamination. You said it was quicklime as a result from calcination right? If dolomite was used for calcination, the contamination would be severe.
For the sodium nitrite: you can make it heating molten sodium (potassium) nitrate with calcium sulfite in excess. After heating you break the solid, dissolve and filter. Calcium sulfite can be made in large quantities from potassium metabisulfite (can be found locally for wine making), sodium hydroxide and calcium chloride (dessicant). The reaction doesn't require a high enough temperature to decompose the nitrate and is quite quick. I found the procedure in the sciencemadness forum, I've tried it and it seems very reliable.
You think making videos is hard? Well we all know that strong comments drive videos. So even harder then creating good content is coming up with funny, and cheeky comments. And that’s coming from a person who’s never made a single video.
The Machine of YouTube is oiled by the blood of the commenters
You have to use carbonates to get it to the correct pH. Guanyl azide undergoes ring closure at a pH of around 10 to form the tetrazole. Since bicarbonate has a pH of 8 so it won't do anything.

1000 g per kg...so, fully pure? :P
that's a weird label lol
