补充资料:含水肼
分子式:H4N2·H20
分子量:50.06
CAS号:7803-57-8

性质:无色发烟液体,呈弱碱性,微有特臭,可燃。熔点-51.7℃,沸点120.1℃,47℃(3.33千帕),相对密度1.032(21/4℃),折射率1.4280。闪点(开杯)73℃。与极易还原的汞、铜等金属氧化物和多孔性氧化物接触时,会起火分解。能与水和乙醇混溶,不溶于氯仿和乙醚。能从空气中吸收二氧化碳。对玻璃、橡胶等材料有腐蚀性。

制备方法:有多种生产方法。1.尿素氧化法将10%的次氯酸钠溶液和30%液碱混合,然后冷却,调整混合,然后冷却,调整混合液中氯和碱成1:1.8的重量比,放入反应锅内。再加入适量的高锰酸钾,搅拌下将尿素溶液加入反应锅,加热至约103-104℃料液沸腾为止。尿素加入量按有效氯计算,有效氯的重量比是76:75。将上述氧化生成物粗肼水加到蒸发器进行真空蒸了,肼气和水气经过盲风器导入接受釜,进行初次提浓。从接受釜,进行初次提浓。从接受釜得到的淡肼水送至筛板塔进行真空提浓,使水合肼含量达到规定值。当含量≥40%时尿素 770次氯酸钠 890030%液碱 52002.次氯酸钠氨化法首先由氯气和烧碱配制成次氯酸钠,然后在3.922×107Pa压力和130-150℃温度下进行合成,得水合肼反应液,经气提脱除多余的氨,再进行蒸发脱盐和精馏得成品水合肼。生产水合肼的较新方法有甲酮连氮法和过氧化氢法。甲酮连氮法是国外七十年代发展起来的新技术。该法是氨在过量丙酮存在下,用氯或次氯酸钠氧化,生成甲酮连氮,再加压水解得到肼。该法优点是收率高,可达95%左右,能耗低。缺点是丙酮的加入,使系统中有有机副产物生成,需要清除,且丙酮蒸汽需处理。过氧化氢法是法国于结纳-库尔曼化学公司开发成功的。于1979年建成年产5000吨(100%)水含肼装置。该法是氨和浓H2O2在甲乙酮、乙酰胺和磷酸氢二钠存在下互相作用,生成甲甲乙酮连氮和水,再加压水解得水合肼。肼的产率以H2O2计为75%左右,该法没有副产物氯化钠,对简化流程和环保有利,并且产品溶易分离,不必进行精馏。但甲乙酮的化学损耗高于甲酮连氮法的丙酮的损耗。

用途:水合肼为强还原剂,是医药、农药、染料、发泡剂、显像剂、抗氧剂的原料;大量用作大型锅炉水的脱氧剂;还用于制造高纯度金属、合成纤维、稀有元素的分离。此外,还用来制造火箭料和炸药等。也用作分析试剂。用作发泡剂的肼衍生物大部分是偶氮二甲酰胺(AC),还有甲苯磺酸肼等。用作医药的衍生物,肼量较多的是异烟肼、芬基氨硫脲和苯磺酰氨硫脲,还有抗精神病药1-异烟酰基-2-异丙肼、抗癌药醛基肼衍生物、抗感染药5-硝基呋喃甲叉肼衍生物、抗生素唑啉头孢菌素、利尿降压药肼苯哒嗪、抗肿瘤药甲基苯肼等。用作农药的肼衍生物有植物生长调节剂马来酰肼衍生物、杀鼠剂二鼠剂硝基苯肼、杀虫钉菌剂吡唑衍生物与5-硝基呋喃氨硫脲,除草剂氨基三唑等。在日本,肼的用途分配中1/3以上是作锅炉水的去氧剂,发泡剂用的肝(包括水合肼和硫酸肼)约占30%,用于蒙胧药占10%。
