18.4: Sulfonation of Benzene (an EAS Reaction)
Sulfonation is a reversible reaction that produces benzenesulfonic acid by adding sulfur trioxide and fuming sulfuric acid. It is important to note that the chemical formula of the sulfonic group …
Sulfonation of Benzene - Chemistry Steps
The sulfonation of benzene is typically achieved by reacting with fuming sulfuring acid which is a mixture of H 2 SO 4 and sulfur trioxide (SO 3) known as oleum. The reaction follows an …
Electrophilic Aromatic Substitutions (2) - Master Organic Chemistry
2018年4月30日 · Upon addition of acid, however – the usual choice being sulfuric acid, H 2 SO 4 – a rapid reaction with benzene ensues. The key to the process is protonation of OH on nitric …
Benzene Reactions - Sulphonation Of Benzene, Nitration Of …
Sulfonation of benzene is a process of heating benzene with fuming sulphuric acid (H 2 SO 4 +SO 3) to produce benzenesulfonic acid. The reaction is reversible in nature. Due to higher …
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 …
