Sulfuric acid as a catalyst

[samsiexD]

Question : apart from esterification what other reactions use sulfuric acid as a catalyst?

Thanks~

Acid-catalysed hydration of an alkene, I think.
When you add water to an alkene under acidic conditions to get the double bond broken and an alcohol formed

EDIT: Acutally, I think sulfuric acid isn't specifically used for this, maybe phosphoric acid, nevermind

If you look up sulfuric acid on Wikipedia, there's a whole catalyst section

Well...if you really want to know...the nitration of benzene also requires sulfuric acid as a catalyst. TNT can be formed by nitrating toluene (methyl benzene) three times. I don't know why you'd want to know this though.

Its for my sac revision

Ah I meant why you'd want to know about the nitration of benzene

Oh haha, ah well it's nice to learn new things

Sulphuric acid can be used in the oxidation of alcohols to carboxylic acids.  (here it is used as the source of H⁺ your reaction pathway would be written as Cr2O7^2-/H⁺).
