1:30- I laughed pretty hard at this part cuz I remember doing nitration of nitrobenzene as a lab during my first semester of organic chemistry. The lab book even had a warning in bold and all caps that said to keep the solution between 60 and 70 C during the addition, and if it goes above 70, to shout "leave the area immediately"
@@sheevpalpetine7687 oh for sure, especially how deactivated a tri nitrated benzene would be. I was just assuming in this scenario you'd be already starting with nitrobenzene
@@NerdyNEET Of all the stupid ways one could deal with an over-nitrated volatile substance, that method is most certainly on the less-stupid end of the spectrum...
Not at all! Many of the reactions found on it are referenced too, by the authots from scientific journals and academia. Not all of it is direct drug synthesis either nitrobenzene isnt illegal where I'm from nor is it's synthesis

Add H2SO4 to the benzene first, so that sulphonation can take place and then add it to HNO3 with some extra H2SO4 for NO2+ electrophile generation. Keep benzene in high amounts so that we can reduce the chances of multiple nitrations. I remember this method from my textbook for making picric acid. It gives a pretty good yield
What are your thoughts on adding the chilled mixed acids via a dropping funnel into chilled benzene? Maintaining benzene in excess should prevent any formation of multinitrated products, and if benzene is in a molar excess then separation of benzene and nitrobenzene should be eqasy and safe.
I was learning preparation of nitro benzene & I searched a video regarding it & I saw Ur video sir , whole topic got clarified..thank you so much sir for crystal clear explaination
One of the reasons one can get a low yield from this reaction is the entrainment of nitrated product by calcium chloride. I think you can get a better yield if you a) use only about 1g of calcium chloride, an b) dry the crude product before distillation. A side note, this was the very first organic reaction I attempted in high school, in 1969.
Norman Reitzel dude. I’m a chem teacher and we teach this mechanism, as well as the reduction of nitrobenzene to phenylamine to the IB Chem HL course but by today’s safety standards none of this is even remotely legal. I wish it was 50 years ago haha.

Firstly... Damn man you are so awesome, the way how you explained everything was so fantastic. Secondly.. Thank you so much you helped me in making my assignment 🙂 Lots of love to you bro
You probably don't need to be concerned about the formation of 1,3-dinitrobenzene and 1,3,5-trinitrobenzene. They require harder conditions, at least fuming nitric acid instead the 65% HNO3, and a longer reaction time.
so it will be mistake to use let say 90% hno3 and leave all that cook on 2-3h over 150c ? we did that on one experiment and all was same like in this test ,and we only use distil water ,room temp to cool it down under 200c ,so how is possible to get di let alone tri by longer reaction i dont get it
off topic, but can you do a video(s) talking about the different distillation setups i.e. fractional, vacuum, steam, soxhlet and any others there might be. What one would be best for a beginner etc. Please and thank you, that is :)

I had a synthesis lab that I had to do a nitration to acetophenone. I ruined it by letting the nitroacetophenone solution go to about 10 degree celsius. It was terrible.

Came here via a book written by ''Rex Stout '' called ''The red box ''. Murder mystery, this stuff was used to murder someone via skin absorption in the story
ehhh.... i think you'd be better off crystalizing your product out instead of distilling it. crystalization is much safer than distillation in this particular instance. Also... i'd use magnesium sulfate instead of calcium chloride.
i know this is old but can a nitration be preformed 3 times to create tri nitro toulene and since the ch3 ion is a weak activator and directs to the ortho para position but with steric hidnerence wouldnt the para postion be the most favorable? and therefor both ortho and meta since no2 is a strong deactavor can be nitrated to create 2 4 6 trinotro toulene? or would it be to slow

196Stefan2
well, if you heated it enough, the concentration of the nitric acid would probably increase
Concentrated nitric acid is already azeotropic, so the heat would mean that acid was going into the air, rather than becoming more concentrated.
196Stefan2 traces of the dinitrobenzene can easily form.
