Crystal Sodium Sulfide Red Flakes 52

Manufacturer & Exporters of Sodium Sulfide Red Flakes 52 in China

Chemical Names: Sodium sulfide; 1313-82-2; Disodium monosulfide; Na2S; Disodium sulphide; Sodium sulfide

Molecular Formula:Na2S or HNa2S+

Molecular Weight: 79.048 g/mol
Structure:Na2S adopts the antifluorite structure, which means that the Na+ centers occupy sites of the fluoride in the CaF2 framework
, and the larger S2− occupy the sites for Ca2+.

Production
Industrially Na2S is produced by carbothermic reduction of sodium sulfate often using coal:Na2SO4 + 2 C → Na2S + 2 CO2
In the laboratory, the salt can be prepared by reduction of sulfur with sodium in anhydrous ammonia,
or by sodium in dry THF with a catalytic amount of naphthalene (forming sodium naphthalenide):2Na + S → Na2S
