Saponification is a process of cleaving esters into carboxylate salts and alcohols by the action of aqueous alkali. Typically aqueous sodium hydroxide solutions are used. [1][2] It is an important type of alkaline hydrolysis. When the carboxylate is long chain, its salt is called a soap.
Saponification is the hydrolysis of an ester to form an alcohol and the salt of a carboxylic acid in acidic or essential conditions. Saponification is usually used to refer to the soap-forming reaction of a metallic alkali (base) with fat or grease. Example: In the presence of conc., ethanoic acid reacts with alcohol.
Esters can be cleaved back into a carboxylic acid and an alcohol by reaction with water and a base. The reaction is called a saponification from the Latin sapo which means soap. The name comes from the fact that soap used to be made by the ester hydrolysis of fats.
What is Saponification. The process of converting fats, oil, and lipid into soap using an aqueous alkali is called saponification. Vegetable oil and animal fats are triesters or triglycerides that can be saponified in one or two steps.
Saponification is the reaction where an ester is hydrolyzed into an alcohol and a carboxylic acid salt upon the addition of an aqueous base. In this article, we will explain the saponification reaction and its mechanism, as well as its applications to science and beyond!
Saponification is the name of the chemical reaction that produces soap. In the process, animal or vegetable fat is converted into soap (a fatty acid) and alcohol. The reaction requires a solution of an alkali (e.g., sodium hydroxide or potassium hydroxide) in water and also heat.
Saponification is a chemical process in which triglycerides undergo an interaction with lye made from sodium or potassium hydroxide resulting in glycerol as well as a fatty acid salt commonly referred to as “soap.” Triglycerides commonly consist of animal fats or vegetable oils.
Basic Hydrolysis of Esters (Saponification) When esters are treated with sodium hydroxide, they are converted into carboxylate salts, which upon neutralization yield carboxylic acids. This process is called basic hydrolysis of esters, or saponification.
The hydrolysis of fats and oils in the presence of a base is used to make soap and is called saponification. Today most soaps are prepared through the hydrolysis of triglycerides (often from tallow, coconut oil, or both) using water under high pressure and temperature [700 lb/in 2 (∼50 atm or 5,000 kPa) and 200°C].
Slowly, a chemical reaction called saponification would take place between the fat and the hydroxide which resulted in a liquid soap. When the fat and water no longer separated, the mixture was allowed to cool.
