2024年5月24日 · The nitration of benzene requires a mixture of concentrated nitric acid (HNO 3) and sulfuric acid (H 2 SO 4) refluxed with benzene between 25 o C and 60 o C; Since phenol is more reactive, nitration can occur under milder conditions by reacting it with dilute nitric acid at room temperature. If concentrated nitric acid is used, 2,4,6 ...
Benzene Reactions - Sulphonation Of Benzene, Nitration Of …
Common benzene reactions are Nitration of Benzene. Benzene reacts with concentrated nitric acid at 323-333K in the presence of concentrated sulphuric acid to form nitrobenzene. This reaction is known as nitration of benzene.
Nitration and Sulfonation of Benzene - Chemistry LibreTexts
2023年1月23日 · Nitration and sulfonation of benzene are two examples of electrophilic aromatic substitution. The nitronium ion (NO 2+) and sulfur trioxide (SO 3) are the electrophiles and individually react with benzene to give nitrobenzene and benzenesulfonic acid respectively.

Nitration Of Benzene- Introduction, Mechanism And Solved …
2022年11月5日 · Nitration of benzene is an example of electrophilic aromatic substitution reaction. Benzene reacts with concentrated nitric acid in the presence of sulfuric acid to give nitrobenzene. In this reaction sulfuric acid acts as a catalyst. Catalyst is a substance which enhances the rate of chemical reaction but does not take part in chemical reaction.
Nitration of Benzene - Chemistry Steps
Nitration of benzene or its derivatives introduces a nitro (NO 2) group into the aromatic system. The reaction is carried out with a mixture of nitric and sulfuring acids at temperatures above 50 o C.
Nitration of Benzene - Periodic Chemistry
2018年8月20日 · The nitration of benzene is an electrophilic aromatic substitution reaction, in which a nitro group (-NO 2) is introduced onto a benzene ring. This reaction proceeds via the formation of an electrophilic nitronium ion (NO 2 +) from nitric acid (HNO 3), resulting from proton transfer from sulfuric acid (H 2 SO 4). Following the nucleophilic ...
