Fluorosulforic Acid

CAS: 7789-21-1
Molecular Formula: HFO3S
Molecular Weight: 100.0695
Product description:A kind of important acidic solvent, acid is stronger than perchlorate, is the strongest in the simple acid, chemical formula HSO3F, molecular weight of 100.07, colorless liquid smoke, melting temperature 87.3 ℃, boiling point 165.5 ℃, the relative density of 1.74315. Fluoride sulfonic acid refinement of high thermal stability, heated to 900 ℃ is still stable, sulfur impurities make it totally decomposed in the boiling point. In the wet smoke in the air. Can dissolve sulfur, lead, mercury, tin. Soluble in nitrobenzene, soluble in water and explosive violent reaction with water, soluble in alkali. At room temperature with sulfur, carbon, selenium, tellurium, reactions such as lead, but it can react with tin generated gas, mercury can slightly erosion.1. Fluorine of the low melting point of sulfuric acid, low price, low temperature of NMR measurement can be used as a solvent. Inert paraffin in super acid polymerization, degradation and different physical and chemical reaction. 2. Used in the manufacture of pharmaceuticals, and used in organic synthesis.
