Hydrolysis (/haɪˈdrɒlɪsɪs/; from Ancient Greek hydro- 'water', and lysis 'to unbind') is a chemical reaction in which a molecule of water breaks one or more chemical bonds. The term is used broadly for substitution, elimination, and solvation reactions in which water is the nucleophile.[1]

Process and technologies

Acid

Acid hydrolysis is a hydrolysis process in which a protic acid is used to catalyze the hydrolysis reaction. Dilute or concentrated acids help to break down the cellulose and hemicellulose into individual sugars.[2]

Alkali

Alkaline hydrolysis refers to types of nucleophilic substitution reactions in which the attacking nucleophile is a hydroxide ion.
