Abstract
The activity of cation-exchangeable layered clay or crystalline aluminosilicate catalyst in esterification, etherification, hydration, and cracking reactions is promoted by addition of a strong acid such as sulphuric acid, phosphoric acid, hydrochloric acid, hydrofluoric acid or para-toluene sulphonic acid. The further addition of water to the reaction can extend the life of the clay catalyst and in some cases its catalytic activity.
