詳細(xì)信息(中文):
性質(zhì)與穩(wěn)定性編輯
1.如果遵照規(guī)格使用和儲(chǔ)存則不會(huì)分解。
2.避免接觸氧氣,氧化物及水分。在空氣中不穩(wěn)定,加熱氧化生成氫氧化鈉、亞硝酸鈉和氨。400℃開始分解,500~600℃迅速分解。有潮解性,與水激烈反應(yīng)生成氨和氫氧化鈉。在熱酒精中分解。在真空中加熱到300~330℃分解成氮?dú)?、鈉、氫氣和氨氣。易燃、易爆。有腐蝕性。處置逸出物料時(shí)須戴防毒面具與手套,用干燥沙土混合并送至空曠地方,與大量水反應(yīng)后放入廢水系統(tǒng)。對(duì)污染的地面也應(yīng)用水沖洗;皮膚接觸,眼部受刺激,應(yīng)立即用水沖洗;誤入口中,應(yīng)立即漱口,飲水和醋或1%醋酸,然后送醫(yī)院救治。遇水水解,遇空氣氧化,被氧化的氨基化鈉受熱時(shí)容易發(fā)生爆炸。
氨基鈉
氨基鈉
用途編輯
供制氰化鈉,并用于有機(jī)合成的還原劑 脫水劑。也用于醫(yī)藥制造和疊氮化物。
制備或來源編輯
高溫法:由干燥和脫氧過的氨通過250~360℃金屬鈉制得。
氨基鈉
氨基鈉
低溫法:在-33℃以下液氨溶液中,加入金屬鈉,使用三價(jià)鐵鹽做催化劑,反應(yīng)制得。
其他在水溶液中分解為氫氧化鈉和氨。在真空中熱至300~330℃分解為鈉、氮、氫、氨。常保存在苯或甲苯中。

詳細(xì)信息(英文):
Edit properties and stability
1. If the use and storage comply with the specifications will not break down.
2. Avoid contact with oxygen, the oxide and moisture. In the air is not stable, heating oxidation produce sodium hydroxide, sodium nitrite and ammonia. 400 ℃ began to decompose, 500 ~ 600 ℃ rapidly decompose. Has the deliquescence, reaction with water generated ammonia and sodium hydroxide. In the thermal decomposition in alcohol. In a vacuum heating to 300 ~ 330 ℃ is decomposed into, sodium, hydrogen and ammonia nitrogen. Inflammable, explosive. Corrosive. Disposal of escaping material must wear a mask and gloves, use dry sand mixing and sent to the empty place, after reaction with a large amount of water into the waste water system. The ground also application of pollution water flushing; Skin contact, eye stimulation, rinse with water immediately; Into the mouth, should immediately gargle, drink and vinegar or 1% acetic acid, and then sent to hospital. Hydrolysis, under the influence of water in the air oxidation, oxidation of sodium amination, easily exploded when heated.
Sodium amide
Sodium amide
Use the editor
For sodium cyanide, and used for organic synthesis of reductant dehydrating agent. Also used in medicine manufacture and azide.
Preparation or source editor
High temperature method: by drying and deoxidization of ammonia by 250 ~ 360 ℃ was prepared from sodium metal.
Sodium amide
Sodium amide
Method: at low temperature under - 33 ℃ in liquid ammonia solution, add sodium metal, trivalent iron salts used as catalysts, reaction.
Other decomposition in aqueous solution of sodium hydroxide and ammonia. In a vacuum heat to 300 ~ 330 ℃ is decomposed into sodium, nitrogen, hydrogen, ammonia. Chang Baocun in benzene and toluene.
