Fluoroantimonic acid
Fluoroantimonic acid (CAS 16950-06-4), with the formula HF · SbF5, is an exceptionally strong superacid. It is a colourless liquid with a density of 2.885 g/mL at 25 °C and a vapor pressure of 14 mmHg at 18 °C. Purified by triple-distillation, it is primarily used as a powerful reaction medium in organic synthesis, particularly for the preparation of specific organic salts.
Superacidic Reaction Medium
Fluoroantimonic acid serves as an extremely potent acidic medium for challenging chemical transformations. Its high acidity allows it to catalyse reactions that are not feasible with less potent acids.
Preparation of Alkylidene Oxonium Salts
This superacid is an excellent medium for the preparation of alkylidene oxonium salts. This application is crucial in specialised organic synthesis pathways where such intermediates are required.
Electronic Chemicals and Materials Science
As indicated by its classification within electronic chemicals and materials science, Fluoroantimonic acid may find applications in specialised research and development within these fields.
