Even the now very famous Russian-British chemistry professor at Nottingham will admit that he's not a very good synthetic chemist. It takes quite a lot to be a good one.
if the ph Control is needed, you could use a Phosphate buffer solution for the alkaline side. btw your hydrazinsulfate is an acidic buffer on its on, hydrazin is an weak Base, so the korresponding hydrazonium Ion is a weak acid. so your hydrazinsulfate does not need to be impure with sulfuric acid.

It is thought that above reactions (C) and (D) describe the discoloration (and degradation) that occurs in the normal course of drying AGB as employed in the past.
Practice makes perfect friend. I don't want to think anymore about the hundreds of failed experiments, or worse, failed workups. The frustration, the shame, the massive amounts of stupid mistakes.

I did OK or so ithought right up to the point i went to convert it to aminoguanadine corbonate, i performed the work up using Perkla fertiliser which is 40% cyanamide, or so it reports, its also full of powdered graphite wich made it an absolute nightmare during the PH & tempreture controle stage, after much filtering i eventually got my yellow reddish product. i ended up with a pink solution with no precipitate when it was fully nuetralised with bicarb, i shoved it in the freezer just to see what crashed out. All those reagents & time spent over 3 days for what i cant honestly indentify. When it eventually did crytalise it suddenly went in seconds like a chemical ice, what ever work f*ckery i created it certainly was not aminoguanadine. I wanted a sample to test for its medical propertys as aposed to energetics. Very frustrating as i actually had to buy the hydrazine sulfate wich cost a small fortune due to shortages of basic chems over here. Ime going to try & make the cyanamide from scratch this time, i think what ever other sorcery was mixed in with that fertiliser created some form of unidentifyable adduct/complex/slop/abomination during the heating stage.

Also to tell if that supply is being used to manufacture illicit drugs. Lots of pink amphetamine sulphate gets seized by police and they can figure out that the manufacturer bought x-brand sulphuric acid from the hardware store and monitor future purchases, might just be a result of the classification of concentration, but the cops definitely use that technique to catch drug manufacturers.
Dude, the sound on this video is terrible... Does anyone else hear the static? *Edit:* Wait... is that rain? lol. If it is then my bad. That was some hard ass rain if so.
No it's static! The camera I was using had a very small, very bad microphone. It died one day, and started making all this static. With no external mic port, there was nothing I could do! Luckily I worked out some other things to film with pretty quickly, the static didn't ruin too many videos!
@@ExtractionsAndIre Oh ok. I heard you mention the rain in it and thought maybe it was just some particularly terrible rain. Anyways, keep up the good work! Love your vids. Hope you got the TLC and chromotography thing worked out for the Epazote peroxide extract analysis!

I just noticed the part with the chem player text to speech voice. Lol.
Organic chemistry - the quest for brown sludge.
"Practical high yield synthesis of tar and water using new expensive exotic noble metal catalysts"
And the Germans did it in the 1930s.
The fact that you're doin chem at uni and you say you're terrible at it is honestly both very inspiring and slightly depressing
Good news now he has a PhD. Bad news it's in physics not chemistry.
Hi! Nice video. Why don't you link the site where you found the procedure? That way it woud be much more easy to reproduce.
+DiaveD Good idea, I should be doing that, i'll link it now
Glad to help :)
Lighting is ok. Good job.

Please explain how you figured out to use a vacuum cleaner in place of a vacuum pump.
Yess...u r right
Inst that like a pretty obvious improvised solution when you dont have a pump?

I wouldn't had even handled the container of cyanamide with my bare hands...
Why would they dye sulphuric acid?
