Meaning and Definition
A chemical reaction in which a bond is broken by an alcohol, with the alcohol molecule adding across the bond.
A specific type of solvolysis reaction where an alcohol acts as the solvent and nucleophile, cleaving a chemical bond (commonly in esters, acid chlorides, or anhydrides) to form new compounds. It is analogous to hydrolysis but uses an alcohol instead of water.

FAQ
Frequently Asked Questions
Transesterification is the most common and important type of alcoholysis, specifically where one ester is transformed into another. Alcoholysis is the broader term that includes reactions with other compounds like acid chlorides.
In the production of biodiesel, where vegetable oil (triglycerides) undergoes methanolysis (alcoholysis with methanol) to form methyl esters (biodiesel) and glycerol.
No, by definition alcoholysis uses an alcohol. If water is used, the reaction is called hydrolysis.
No, it is a highly specialised technical term used almost exclusively in chemistry and related scientific fields.
A chemical reaction in which a bond is broken by an alcohol, with the alcohol molecule adding across the bond.
Alcoholysis is usually technical/scientific in register.
