Trichloroacetic acid is made by directly reacting chlorine with acetic acid using a suitable catalyst.

It is prepared by the reaction of chlorine with acetic acid in the presence of a suitable catalyst.

At higher temperatures or in the presence of suitable catalysts the reaction proceeds more readily.

Using a suitable catalyst (e.g. Wilkinson's catalyst), it is possible to reduce just one of the double bonds of an allene.

For instance, the disproportionation of hydrogen peroxide is very slow in the absence of a suitable catalyst.

Styrene is a similar liquid monomer at room temperature, which will also polymerize into clear glass-like polystyrene plastic, with addition of a suitable catalyst.

R3 is reversible with an equilibrium pressure of about 0.25 bar at 500 C. R1 and R2 can occur at room temperature with suitable catalysts.

At high temperature and in the presence of a suitable catalyst, ammonia is decomposed into its constituent elements.

The availability of a suitable catalyst is also an important factor in deciding whether to build an alkylation plant.
