Websulfur oxide, any of several compounds of sulfur and oxygen, the most important of which are sulfur dioxide (SO2) and sulfur trioxide (SO3), both of which are manufactured in huge quantities in intermediate steps of sulfuric acid manufacture. The dioxide is the acid anhydride (a compound that combines with water to form an acid) of sulfurous acid; the … WebSulfur trioxide is more reactive than sulfuric acid or its derivatives and is often used for aromatic sulfonation, particularly when modified as its adducts with dioxane or pyridine. The addition of sulfur trioxide across a carbon–carbon double bond to give an aliphatic sulfonic acid is possible, but commonly gives a mixture of products < 54JA3945, 65BSF787 >.
