Esterification is a chemical reaction of an [http://en.wikipedia.org/wiki/Acid acid] with an [http://en.wikipedia.org/wiki/Alcohol alcohol] (R'OH) to form an ester (RCOOR'). | Esterification is a chemical reaction of an [http://en.wikipedia.org/wiki/Acid acid] with an [http://en.wikipedia.org/wiki/Alcohol alcohol] (R'OH) to form an ester (RCOOR'). | ||
Usually esterification refers to reaction between an organic (carboxylic) acid (RCOOH) with an alcohol (R'OH) to form an ester (RCOOR') and water and called '''Fischer esterification'''. | Usually esterification refers to reaction between an organic (carboxylic) acid (RCOOH) with an alcohol (R'OH) to form an ester (RCOOR') and water and called '''Fischer esterification'''. | ||
