补充资料：肼
| 肼 hydrazine 无色油状液体，具有与氨相似的气味，毒性很大 。化学式H2NNH2或N2H4。又称联氨。熔点20℃，沸点113.5℃，密度1.004克／厘米（25℃），在空气中能吸收水分和二氧化碳气体，并会发烟。肼和水能按任意比例互相混溶，形成稳定的水合肼N2H4·H2O和含水31％的恒沸物，沸点121℃。肼也与乙醇互溶，但不溶于乙醚和苯。肼的介电常数很高，液态肼的盐溶液能导电。肼是强还原剂，在碱性溶液中能将银、镍等金属离子还原成金属，可用于镜面镀银，在塑料和玻璃上镀金属膜。肼可由次氯酸钠和尿素或氨的反应制取。用于合成异烟肼、呋喃西林、百生肼等药物，偏二甲肼（CH3）2NNH2用作火箭燃料。肼能使锅炉内壁的铁锈变成磁性氯化铁层，可减缓锅炉锈蚀。 |
