Chemical Properties
slightly yellow powder
Uses
Sodium dodecanoate (sodium laurate) is used in cholloidal chemistry as a nonionic surfactant.
Uses
Sodium Laurate is the sodium salt of lauric acid. It functions as a binder, emulsifier, and anticaking agent.
Definition
ChEBI: An organic sodium salt resulting from the replacement of the proton from the carboxy group of dodecanoic acid by a sodium ion.
Purification Methods
Neutralise it by adding a slight excess of dodecanoic acid and removing it by ether extraction. The salt is recrystallised from the aqueous solution by adding pure Me2CO and repeating the process (see sodium decanoate). It has also been recrystallised from MeOH. [Beilstein 2 IV 1085.]
