Meaning and Definition
A chemical reaction where an ester is transformed into another ester by exchanging the organic group.
A process, often catalysed, involving the interchange of alkoxy groups between an ester and an alcohol, acid, or another ester, crucial in producing biodiesel, polymers, and pharmaceuticals.

FAQ
Frequently Asked Questions
No. Saponification is the hydrolysis of an ester with a base to form a carboxylic acid salt (soap) and an alcohol. Transesterification exchanges one alkoxy group for another, preserving the ester functional group.
It is a key reaction for modifying esters. Its major industrial application is converting triglycerides (fats/oils) into biodiesel (fatty acid methyl esters). It is also vital in synthesizing pharmaceuticals, plastics (like polycarbonates), and fine chemicals.
For biodiesel production, strong bases like sodium or potassium methoxide are common. For sensitive syntheses, enzymes (lipases) or acids may be used as catalysts.
Yes, but the verb form 'transesterify' is less frequent than the noun. It is perfectly valid in technical writing (e.g., 'The oil was transesterified').
A chemical reaction where an ester is transformed into another ester by exchanging the organic group.
Transesterification is usually technical/scientific in register.
