Base hydrolysis of an ester is called?
Base hydrolysis of an ester is known as saponification, where the ester is hydrolyzed in the presence of a strong base (e.g. NaOH) to form a carboxylate salt and an alcohol. This reaction is commonly used in soap-making processes.
What is the difference between trans-esterification and esterification processes in methyl esters?
esterification -----> ROH + R'-COOH -------> R'COOR acid with alcohol gives ester transesterification ROH + R'COOR'' -------- > R'COOR change of alkyl group present with R'COO by using a alcohol if you want to http://en.wikipedia.org/wiki/Transesterification Esterification is the general name for a chemical reaction in which two reactants (typically an alcohol and an acid) form an ester as the reaction product. H3C-COOH + HO-CH2-CH3 → H3C-COO-CH2-CH3 + H2O Transesterification is the process of exchanging the alkoxy group of an ester compound with another alcohol. These reactions are often catalyzed by the addition of an acid or base.
Why mineral oil does not undergo saponification?
Mineral oil is a non-polar compound with long hydrocarbon chains and lacks the functional groups needed for saponification, such as ester functional groups found in triglycerides. Saponification is a reaction that involves breaking down ester bonds in fats and oils, so without these bonds, mineral oil cannot undergo saponification.
What is the Saponification value of Glycerin?
Glycerin and soap are the bye-products of saponification. The saponification value of glycerine are values of the percentage of lye it takes to convert one unit of fat, oil or fatty acid into glycerin.
Is condensation the same as esterification?
No, condensation and esterification are not the same. Condensation is a chemical reaction in which two molecules combine with the loss of a small molecule (like water), while esterification is a specific type of condensation reaction between an alcohol and a carboxylic acid to form an ester and water.
Why is saponification reaction is considered to be the reverse of an esterification reaction?
saponification is considered to be the reverse process of an esterification reaction due to the fact that esterification is combining an alcohol and a carboxylic acid but a saponification is breaking apart the ester by adding an NaCl molecule (soap) to the chain of carbons.
What are sponification and esterfiction?
Saponification is the process of making soap by reacting fats or oils with an alkali such as sodium hydroxide or potassium hydroxide. Esterification is the chemical reaction between an alcohol and a carboxylic acid to form an ester and water. Both processes are important in organic chemistry for creating different compounds with specific properties.
What is the role of ethanol in saponification?
Ethanol is sometimes used in saponification processes as a solvent to dissolve oils and fats, which helps facilitate the reaction between the fats and the alkali to produce soap. Ethanol can also act as a catalyst to speed up the saponification reaction.
Base hydrolysis of an ester is called?
Base hydrolysis of an ester is known as saponification, where the ester is hydrolyzed in the presence of a strong base (e.g. NaOH) to form a carboxylate salt and an alcohol. This reaction is commonly used in soap-making processes.
Meaning of esterification?
esterification is the formation of esters between the reaction of alkanol and alkanoic acid
Why do you think ethanol is used in saponification process?
Ethanol is added to hasten saponification.
What happens when fatty acid reacts with NaOH?
what happen when fatti acid react with the NaOH

How do you saponification stearic acid?
Saponification is not applied to pure stearic acid; stearic acid esters are used.
How do you write esterification equations?
Esterification Reaction: When an alcohol ( mostly primary) alcohol is treated with carboxylic acid in the presence of H2 SO4 sweet smelling compound is formed which is called ester. The reaction is know as esterification reaction.
Between butter and margarine which one got higher saponification value?
margarine has saponification value more then butter
