Nitrobenzene : Preparation

Hello friends , in this video we will synthesise nitrobenzene by the direct nitration of benzene by the nitrating mixture.
The nitrobenzene was then washed with NaOH and dried with anhydrous calcium chloride
be safe in home during this pandemic season and try to watch all my videos.
This video has been recorded and edited with much effort and difficulty. Lack of proper equipment and chemicals can make video look unfinished. I request your love and support in donations also.

Nitro compounds are the best compounds! Excellent video, hace a nice day!!

[@SamSam-tn9uh]

Thank u. I can't tell you how helpful your videos are for those who wanna learn how to make these compounds but don't have the raws

[@vibzzlab]

Thank you 🥰

[@abasabasi2328]

Thanks useful and full detail.

[@YASH-qj5ni]

Great video sirji....

[@nuclearthreat545]

First!!!

[@chariotofknowledge9099]

Sir,in the end you just filtered out the nitrobenzene from cacl2?right?

[@foc2241]

Nitrobenzene is a cool compund, I did it also once :D

[@SodiumInteresting]

Smells too nice for such a toxic chemical 🙃

[@jamesg1367]

Very nice! Food grade!

[@SodiumInteresting]

Lol 😆

[@letsstart4505]

Kindly make a video on synthesis of para amino phenol from nitrobenzene

[@orochinchin3998]

Did it work if i use comersial HNO3(68%) instead of concentrated HNO3?

[@SodiumInteresting]

Not ideal I think

[@Создатель-з7ъ]

Yes, it works kinda good if you use 98% H2SO4. I prepared nitrobenzene with 68% HNO3 and the reaction yield was 78,7% of theoretical.

[@mominaan36]

Mine started vigorous reaction suddenly, while heating in your designed water bath, with emission of brown smoke up to roof. The solution first turned dark brown, then black and then green in a sec. When I poured it into water it turned white solution. That's what happened with me. Now sir please solve the mystery.....

[@mominaan36]

@@vibzzlab well sir if I am not wrong in remembering, you said temperature should not exceed 60 degrees?I was trying to provide precise temperature according to your guidance.

[@mominaan36]

@@vibzzlab last day I performed it with 40degree but still it got vigorous

[@atari7001]

@@mominaan36sounds like a runaway nitration. If that’s Celsius, that seems high. nitrations usually happen best at ice cold temps.

[@petyamc7944]

When i added 5m sodium hydroxide solution i had tree layers one red the bottom orange the middle and light yellow at the top. Can you please explain it?

[@Создатель-з7ъ]

I found out what it is. Apparently, due to the presence of impurities, such as zinc dust, when a NaOH solution is added, part of the nitrobenzene will be reduced to azobenzene, whose color is bright orange, and the density is lower than nitrobenzene.

[@petyamc7944]

@@Создатель-з7ъ Thanks for your answer.

[@YASH-qj5ni]

Kya 99.9% me rate kya he

[@umapatra6317]

Sir I am also your subscriber , do you supply me the row meterial of Nitro benzene
