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. The saponification of ethyl acetate gives sodium acetate ...
Alkaline hydrolysis of esters is also known as saponification. A base such as sodium hydroxide is required in stochiometric amounts. Unlike acid-catalyzed ester hydrolysis, it is not an equilibrium reaction and proceeds to completion.
Granville apparently thought that the waxy material from which he made the candles had been used to preserve the mummy, rather than its being a product of the saponification of the mummified body. [4] The body of the "Soap Lady", whose corpse turned itself into adipocere, is displayed in the Mütter Museum in Philadelphia, Pennsylvania. [5]
The higher the saponification value, the lower the fatty acids average length, the lighter the mean molecular weight of triglycerides and vice versa. Practically, fats or oils with high saponification value (such as coconut and palm oil) are more suitable for soap making.
In this reaction, sodium hydroxide acts as an agent to make the solution alkaline, which aluminium can dissolve in. 2 Al + 2 NaOH + 2 H 2 O → 2 NaAlO 2 + 3 H 2 Sodium aluminate is an inorganic chemical that is used as an effective source of aluminium hydroxide for many industrial and technical applications.
A $3 million mansion in a high-end Connecticut neighborhood met a fiery demise on Thanksgiving when the home was inundated in flames from a turkey frying inside a garage.
