Magic Acid price

Product name:Magic Acid
CAS
: 23854-38-8
Molecular Formula: SbF5·HSO3F
Molecular Weight: 316.82
Product description:With high strength and high dielectric constant, can make the electrolyte electrolyte, can make the very weak alkali protons. Therefore, super acid has been widely used in chemistry and chemical production applications. Super acid can be prepared and stable alkanes are carbon ion solution, can also be prepared many halogen cation, and even the stability of ion crystal salt can be obtained. As a kind of good catalyst, especially super acid can be response to make some difficult to under milder conditions, is widely used in organic synthesis. Liquid super acid can be used as a saturated hydrocarbon cracking, reunion, isomerization, alkylation catalyst, solid super acid used as n-hexane isomerization in petroleum chemical industry, such as low molecular weight of polymerization catalyst.
