What's the purpose of an ice bath when preparing a nitration mix from KNO3?
Most preparations for nitrocellulose from $\ce{(KNO3 + H2SO4)}$ mixture require the use of an ice bath during the process of dissolving $\ce{KNO3}$ into $\ce{H2SO4}$. Last time I did this I omitted ...

Can we convert phenol to para-nitrophenol via nitrosophenol?
Our class 12 text book says that if we treat phenol with mixture of concentrated $\ce {HNO3}$ and $\ce{H_2SO_4}$, instead of nitration, the ring is oxidized to quinone.
So, the book proposes that we ...

Nitration of pyrrole with sulfuric and nitric acids
Would 2,5-dinitropyrrole be a product of nitration of pyrrole with $\ce{H2SO4/HNO3}$? It seems that 2,5-dinitropyrrole is not formed when using $\ce{Ac2O/HNO3}$ (ref 1). Is this just because of the ...
