Nitration Video
https://www.youtube.com/watch?v=bnNt89dELfQ
I've had to make a bunch of videos for my students' experiments (because they can only come in to do half of them, due to COVID). I thought this one
might be good enough to share (despite the slip-up where I said nitric instead of sulphuric).
PS- no slight against you guys about the "not for amateurs" disclaimer. Just covering my legal butt.

Beautiful video, thx for sharing. I've never performed this nitration. I see you used methylester of benzoic acid. Couldn't be benzoic acid nitrated
directly? Does the methylbenzoate offer better yield or purer m- isomer product with less o- and p- nitro isomers contamination?
here I found that keeping T very cold as you did prevents o- sideproduct to form, but this is nitration of benzoic acid, not its methylester:

I was following this prep: http://www.orgsyn.org/demo.aspx?prep=CV1P0372
The same authors give this: http://www.orgsyn.org/demo.aspx?prep=CV1P0391
Perhaps the original paper gives a reason that this might be preferred to direct nitration of benzoic acid.
