九水硫化钠 (CAS No.1313-84-4)
- 物化性质
- 白色结晶，易潮解；工业品因含杂质常为粉红、棕红色、土黄色块。易溶于水，微溶于醇，不溶于醚，水溶液呈强碱性。溶于硫黄生成多硫化钠。与酸反应放出有毒易燃的硫化氢气体，燃烧时释放二氧化硫气体。能吸收空气中的二氧化碳而产生硫化氢。熔点约50℃，密度约1.427 g/cm³。
- 技术参数
- 纯度≥99% 熔点约50℃ 密度（20℃）约1.427 g/cm³ 易溶于水，微溶于醇，不溶于醚 水溶液呈强碱性
English description（英文原文，共 1153 字符）
Product Name:Sodium sulfide nonahydrate
English Name:Sodium sulfide nonahydrate
CAS No.:1313-84-4
Aliases:disodium sulfide nonahydrate, sodium monosulfide nonahydrate
Molecular Formula:Na2S·9H2O
Physical Properties:White crystalline solid, hygroscopic; industrial product often appears pink, brownish red, or earth-yellow lump due to impurities. Freely soluble in water, slightly soluble in alcohol, insoluble in ether; aqueous solution is strongly alkaline. Dissolves in sulfur to form sodium polysulfide. Reacts with acids to release toxic and flammable hydrogen sulfide gas, and emits sulfur dioxide when burned. Absorbs carbon dioxide from air to liberate hydrogen sulfide. Melting point about 50 °C, density about 1.427 g/cm³.
Uses:Used in the production of sulfur dyes and organic intermediates, as a reducing agent, depilatory, and mineral flotation agent, and also for preparing sodium thiosulfate and sodium polysulfide.
Technical Specifications:
Purity ≥ 99%
Melting point: about 50 °C
Density (20 °C): about 1.427 g/cm³
Freely soluble in water, slightly soluble in alcohol, insoluble in ether
Aqueous solution is strongly alkaline
