詳細

詳細

Sodium acetate trihydrate can be obtained from the crystallization of sodium acetate in water. On heating at 75°C, it melts, while on heating above 120°C it loses water of crystallization and gets converted into anhydrous form.[1] The hyperfine proton and ¹³C splittings have been evaluated by recording ESR spectra of its irradiated single crystals. ESR studies suggested the existence of trapped methyl radicals.[2] Its crystals are monoclinic and its crystal structure has been investigated by photographic methods. Unit cell parameters were evaluated.[3]

アプリケーション

Sodium acetate trihydrate may be used in the fabrication of silicone/sodium acetate trihydrate hybrid, a water-responsive shape memory hybrid.[4]
