fuming sulfuric acid;oleum
Molecular formula :
MW :

nature : H2SO4 xSO3 sulfur trioxide dissolved by the concentrated sulfuric acid from colorless to brown, oily liquid. Its density, melting point, boiling point and so free with the SO3 content and different. Using the 20% oleum (104.5% H2SO4), the density of 1.9, -11 ° C melting point. Boiling Point 166.6 ° C There were also 40%, 60%, 66% and other varieties. Heating or decompression, SO3 escape, and the case of moist air to form smog. There is a strong dehydration, and sulfonated role. Mainly for sulfonation agent and nitrification reaction of dehydrating agent, and for refined petroleum products.
