谈起强酸,人们自然会想起硫酸、盐酸和硝酸。但近年来出现了比这些强酸强的多的酸,已在化学方面发挥其作用。加拿大的Gillespie开发的各种卤磺酸或它们与金属氟化物的组合,即是一些所谓超强酸(Superacid)。原来超强酸这个词是五十多年前Hull和Conant使用过氯酸进行研究时,发现它能够和醛、酮这类弱碱性化合物生成盐,所以把这类酸称之为超强酸。现在把比100%硫酸更强的酸定义为超强酸。虽然超强酸在半世纪前已经出现,但只 Talking about strong acids, people naturally think of sulfuric acid, hydrochloric acid and nitric acid. However, more acids than these strong acids have appeared in recent years and have played a role in chemistry. The various haloformates developed by Gillespie in Canada or their combination with metal fluorides are known as Superacid. The original super acid is the word Hull and Conant more than fifty years ago when using perchloric acid, Hull and Conant found that it can form salts with weakly basic compounds such as aldehydes and ketones, so this kind of acid is called superacid. The acid which is stronger than 100% sulfuric acid is now defined as superacid. Although superacid has appeared half a century ago, only
