esterification method for acids
What is the esterification test for acids?
Carboxylic acid reacts with alcohol in the presence of concentrated sulphuric acid to form a sweet-smelling ester.
This reaction is known as esterification.
Note: The formation of a sweet-smelling compound indicates the presence of a carboxylic group in the given organic compound.What acids are used in esterification?
This reaction is called the Fischer esterification.
Notes: The reaction is actually an equilibrium.
The alcohol is generally used as solvent so is present in large excess.
Many different acids can be used; it's common to see just “H+”, although H2SO4 (sulfuric acid) and TsOH (tosic acid) are also often used.What is the process of acid esterification?
When primary alcohol is treated with a carboxylic acid in the presence of sulphuric acid a compound is formed.
This compound has a sweet smell.
The compound obtained is called ester.
The chemical reaction occurring in the formation of the ester is known as an esterification reaction.Esters are produced when carboxylic acids are heated with alcohols in the presence of an acid catalyst.
The catalyst is usually concentrated sulphuric acid.
Dry hydrogen chloride gas is used in some cases, but these tend to involve aromatic esters (ones where the carboxylic acid contains a benzene ring).22 jan. 2023
