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 ...
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.
The meltable base is usually naturally rich in glycerine, a by-product of saponification that has humectant and emollient properties, whereas commercial soap bars have often had this component removed. As with the rebatching method, it can be considered a misnomer to refer to the melt and pour process as soap making. The process has much in ...
This reaction, saponification, is the basis of soap making. The alkoxide group may also be displaced by stronger nucleophiles such as ammonia or primary or secondary amines to give amides (ammonolysis reaction): RCO 2 R' + NH 2 R″ → RCONHR″ + R'OH. This reaction is not usually reversible. Hydrazines and hydroxylamine can be used in place ...
Sodium stearate is produced as a major component of soap upon saponification of oils and fats. The percentage of the sodium stearate depends on the ingredient fats. Tallow is especially high in stearic acid content (as the triglyceride), whereas most fats only contain a few percent. The idealized equation for the formation of sodium stearate ...
To this end, hydrolysis is conducted in water at 250 °C. The cleavage of triglycerides with base proceeds more quickly than hydrolysis, the process being saponification. Saponification however produces soap, whereas the desired product of hydrolysis are the fatty acids.
