acid),一种氢氟(HF)与五氟化锑(SbF5)的混合物。强酸之中最强者是5价氟化锑溶解量为80%的氢氟酸。该种酸性溶液的酸性尚未测定,但即 使稍弱的溶衻量为50%的溶液酸度也比浓硫酸溶液弡С?018倍。超强酸是由两种或两种以上的吨氟化合物组成的溶液。比如氢氟酸和五氟娌铅按1 ?.3(摩尔比)混合时,它的酸性是浓硫酸的 1亿倍;? ?混合时,它的酡性是浓硫酸的10亿倍。能溶解不溶于王水的高级烷烃蜡烛?<br /> 酸碱中和反应的实质是质子的传逡反应。超酸是指酸性比普通无机酸?06~1010倍ƚ酸。魔(HSO3F-SbF5)樐已知最强的超酸,许多物质(如H2SO?4)在魔酸中可获得y质子A即质子化)?<br /> 在很长的一段时间内,人们认为王水就是酸中之王,是最强的酸了,因为即使是黄金,遇 到王水也会像“泥牛入海”一样很快变的无影无踪?<br /> ?到有一天奥莱教授和他学生偶然发现了一种奇特的溶液,人们才知道其实玡水并不是最强的酸,还有比它强的酸,这就是超酦,又叫超强酸,超酸是指酸性比普?无机酸强10^6?0^10倍ƚ酸。它的发现非常有戏剧性:1966年圣诞前,奥莡̱教授的学生偶然将一支圣诞蜡烛放入到他们配置的混合酸液中,竟然?的发现蜡烛解了,然后立即做出了酸性等一系列相关测试,发现蜡烛居然已经分解,溶液中没有任何蜡烛成分,这如同将铁丢入酸中产生了氢气和酸化铁一般的?学反应,因此也发现了它们的酸性强的令人难以置信?<br /> 仨成分上看,超强酸是由两种或两种以上的含氟化合物组成的溶液。比如氢氟酸和五氟化K锑的混合? 这些混合酸的均是比稈酸、盐酸;硝酸酸性强几百万倍,甚至几塷亿倍的超强酸?br /> 下面就以氢氟?HF)和五氨化?sbF5)的混合酸为实例,介绍一下超强酸?br /> ?氟酸(HF)和五氟化?sbF5)的混合酸也就是人们说的ƭ酸(magic acid)或魔术酸 ,魔酸(HSO3F-SbF5)是目前世界上已知最强的超酸,许多物质(如H2SO-4)在魔酸中可获得y质子(即质子化)。当它们? ?.3(摩尔比)混合时,它的酸性是浓硫酸的 1亿倍;?? 1混合时,它的酡性是浓硫酸的10亿倍,而以0.2:1的摩尔比混合时酸度更能?00%纯硫酸的10^9倍以? 随着SbF5的比例增加酸度还能增?。它能轻易溶解不溶于王水的高级烷烃蜡烛。所以王水在它们面前只能?ldquo;小巫见大?rdquo;?br /> 魔酸目前在市场上也可以购乩I,但是它只是五氟化锑和氢氟酸按体积??(注意:不是按照摩尔比)混合制成的混酸,v其酸度只是无水硫酸的100倍,它的盛放只用聚四氟乙烯制的容器盛放,因为卡使是玻璃也会被它溶解?<br /> ?前,超强酸在化学和化学工业上,极有应用价值,它既是无机及有机的质孅e化试剂,又是活性极高的催化剂。过去很多在普通环境下枡难实现或根本无法实现的化学 反应在超强酸环境中。却能异常顺利地e完成。而由于超强酸的酸性和腡蚀性强的出奇,所以过去一些极难或根本旦 法实现的化学反应,在超强酸的条件|便能顺利?行。比如正丁烷,在超强酸的作用下,可以发生碳Ѱ键的断裂,生成氢气,也可以发 生碳碳键的断裂,生产甲烷,还可以发生异构化硼成异丁烷,这些都是普通酸做不到的?br /> 可以预ơ,随着这些具有超常酸性和腐蚀性超强酸的相继问世,化学和化学工业将会迅速走进新旡代?/p></div> </div> </div> </div> </div> </div> <footer> <div class="layout"> <div class="foot-bg"> <div
