sulfur trioxide;sulfuric acid anhydride
Molecular formula :
MW :
CAS :

nature : SO3 or (SO3) n also known as sulfuric acid anhydride. Colorless solid. With three allotropy. Alpha-type, temperature 62 ° C. Β-type, temperature 32.5 ° C. Γ-type, the temperature of 16.8 ° C. Usually mix, the temperature is not constant. Easy sublimation. Γ-type boiling in 45 ° C From sulfuric acid soluble in water, soluble in concentrated sulfuric acid sulfate from smoke, a lot of heat simultaneously. Corrosive weak. The strong effect. For system and chlorosulfonic acid sulfate, organic compounds are used in the sulfonation. By sulfur dioxide in the presence of oxidation catalysts derived.
