Making The Most VIBRANT Pink dye from scratch

[@chemistryofquestionablequa6252]

Very nice, love chemistry that's well done with minimal or improvise equipment.

Thanks !

the vacuum setup is the best thing i've seen all day. another excellent goofy chemist found on youtube :D

No, it's just a distraction and poor taste.

@@SbF6H I get what you mean but it's a video and not an article or scientific publication so ig meme have their place here

@@jam_kemist3986 exactly, it can be said that it is not a scientific article from the professionalism of your vacuum pump

P-nitroaniline is also very cool precursor for some dyes I have recorded a vid about it but it isn’t public already

You will spill less if you use a small funnel and a flask to pour your corrosives; you dont have to be as slow and careful with the bottle and it wont cling to the threads as much. Alternatively, use a glass rod; the surface tension will cause the liquid to grab the rod and flow into tge beaker rather than onto the bottle and down onto the table.

[@jam_kemist3986]

@@jamide3001 ye thanks for the advice I knew about the rod trick but I don't have a glass one

Your scale asked me to pass along a message, which was "please kill me". Haha Jokes aside, love the content. Thanks

Hey, I was thinking about the mechanism of the final step, the aniline probably attacks the aldehyde carbonyl kicking the electrons up to the oxygen, this is then protonated all the way up to -OH2+ which leaves as water, then another aniline can come in and attack the resonance stabilised carbocation, giving you the dye.

Can email you a picture if you want

Oh wow thanks a lot for the effort, couldn't bother myself 😂 if you send it to me I'll make it into a post Here's my email : [e-mail]

What's that song here at 3:12 in the background? I love it! (I think I found it: Vivaldi intrumental - for wren by Yokalli)

[@jam_kemist3986]

It's a Vivaldi drill remix, I don't have the link tho sry

[@KrashFries]

it could be worth passing the H2S through a weak base solution (sodium acetate for example) in order to remove the so2 thats formed from impure sodium polysulfide (the reaction between S8 and NaOH produces sodium polysulfides but also sodium thiosulfate, which decomposes in acid to form S and SO2. alternatively, reacting paraffin with S8 with charcoal as a catalyst yields clean H2S

[@jam_kemist3986]

@@KrashFries yeah you're right, that could be the reason I only got like 30% yield on the p-aminobenzaldehyde step instead of the 50-60% in literature

[@gianfrancosabadini3608]

Great video! I really enjoyed it. At 10:55, though, I believe the mechanism might be radical-based, as it’s unlikely that hydroxide can abstract a hydrogen from toluene. Still, thanks for the clear explanations throughout!

[@jam_kemist3986]

Thanks ! I didn't found anything better so I guess we'll never know

[@Exotic_Chem_Lab]

Beautiful

[@hlakanipetros6670]

You should try using acetanilide rather than aniline, to prevent side reactions

[@jam_kemist3986]

Didn't have any but would acetanilide also make pararosaniline or another dye?

[@simonderyck9309]

i was just reading about these type of dyes too

[@Moritz___]

Just love it

Very cool

1:32 are you sure you are not making TNT?

[@jam_kemist3986]

@@fabriziomessina6734 yes, there might be some dnt contamination but the 3rd nitration is pretty hard to do and you need heating for a long time and more nitric acid of course I used iced to get the least dnt contamination
