中文百科

超强酸

超强酸是指比纯硫酸酸性更强的酸。

简单的超强酸包括三氟甲磺酸和氟磺酸,它们的酸性都是硫酸的上千倍。在更多的情况下,超强酸不是单一纯净物而是几种化合物的混合物,如王水。

超强酸这一术语由詹姆斯·布莱恩特·科南特于1927年提出,用于表示比通常的无机酸更强的酸。乔治·安德鲁·欧拉因其在碳正离子和超强酸方面的研究获得1994年诺贝尔化学奖。

不过由于酸碱理论的不同,故讨论哪种酸酸性最强是没有意义的。

英语百科

Superacid 超强酸

According to the classical definition, a superacid is an acid with an acidity greater than that of 100% pure sulfuric acid, which has a Hammett acidity function (H0) of −12. According to the modern definition, superacid is a medium in which the chemical potential of the proton is higher than in pure sulfuric acid. Commercially available superacids include trifluoromethanesulfonic acid (CF3SO3H), also known as triflic acid, and fluorosulfuric acid (HSO3F), both of which are about a thousand times stronger (i.e. have more negative H0 values) than sulfuric acid. Strong superacids are prepared by the combination of a strong Lewis acid and a strong Brønsted acid. A particularly strong superacid is fluoroantimonic acid.
