General description
Sodium acetate is a colorless compound and its crystals belong to the monoclinic crystal system. Sodium acetate trihydrate can be obtained from the crystallization of sodium acetate in water. Its trihydrate loses water of crystallization on heating at 75°C, while on heating above 120°C, anhydrous sodium acetate is obtained. It can be synthesized by reacting sodium carbonate or sodium hydroxide with acetic acid. It is widely employed in the organic laboratory for the preparation of buffer solutions. It has been reported to inhibit the growth of Listeria monocytogenes.
Application
Sodium acetate may be used in the following studies:
- Separation and quantification of tartrazine (E 102), amaranth (E 123), erythrosine (E 127) and indigotine (E 132) in soft drinks by reverse phase HPLC method.
- Preparation of guanidine solution required for the total RNA preparation.
- Enantiomeric enrichment of (2S)-2-methyl-2-(2-propen-1-yl)-cyclohexanone.
