  Beschreibung

  General description

  Sodium acetate trihydrate can be obtained from the crystallization of sodium acetate in water. It loses water of crystallization on heating at 75°C, while on heating above 120°C, anhydrous sodium acetate is obtained. Its aqueous solutions are basic in nature.^[1] ESR spectra of its irradiated single crystals have been studied at 77°K. The hyperfine proton and ¹³C splittings indicated the presence of trapped methyl radicals.^[2] Its crystal structure has been examined.^[3]

  Application

  Sodium acetate trihydrate may be used in the preparation of silicone/sodium acetate trihydrate hybrid.^[4]

  Other Notes

  Enzyme substrate for acetate kinase (EC 2.7.2.1)
