Magic acid acidity range

Methane reacts in superacid medium with the formation of its homologues (ethane, propane,. ..) and hydrogen [41 ]. Magic acids promote the oligomerization of alkanes (even methane) with the formation of oligomers ranging from 100 to 700. The ease of attack follows the trend [42j /iO-Cj > rr-Ca > Ci > C2 C t. [Pg.254]

HF-SbFs is probably the strongest liquid superacid system, and has the widest acidity range [2]. Compared with the widely used magic acid system, fluoroaromatic acid is even more acidic with the same molar concentration of SbFs. For example, fluoroaromatic acid with 0.5 % SbFs has a Ha of -21, whereas Ha for HSOsF-SbFs with the same amount of SbFs is only -17 [44]. HSbFe has an estimated Ha of -30 [2]. The X-ray structure of the 1 1 HF SbFs complex has recently been established [45]. [Pg.530]

The major reason for the wide application of the Magic Acid system compared with others (besides its very high acidity) is probably the large temperature range in which... [Pg.298]
