When keeping the pH at a constant level but changing the buffer concentration a change in rate signals a general acid catalysis.

The removal of the D-glucose leaving group may be facilitated by Mg-dependent acid catalysis.

In biochemistry, many enzymes employ acid catalysis.

The reaction proceeds by acid catalysis where the double bond in 7 opens to form the carbocation 8.

Sodium borohydride will reduce chloramines, but this reaction is greatly sped up with acid catalysis.

Only under Lewis acid catalysis do these reactions occur under synthetically useful conditions.

It is often difficult to distinguish between hydrogen-bond catalysis and general acid catalysis.

Arboreol can be transformed by acid catalysis into gmelanone.

Orthoesters can be prepared by the reaction of nitriles with alcohols under acid catalysis:

However, biodiesel produced from other sources or by other methods may require acid catalysis, which is much slower.
