WebSulfur trioxide (SO 3) is an oxide of sulfur. It is released during the combustion of sulfur bearing fuels. [ 1] Sulfur dioxide in the presence of vanadia catalyst oxidizes to form sulfur trioxide. The kinetics of this reaction has been studied. [ 2] Density function theory and ab initio methods have been used to study the hydrolysis of SO 3 to ... Sulfur trioxide is an oxidant. It oxidizes sulfur dichloride to thionyl chloride. SO 3 + SCl 2 → SOCl 2 + SO 2 Lewis acid. SO 3 is a strong Lewis acid readily forming adducts with Lewis bases. With pyridine, it give the sulfur trioxide pyridine complex. Related adducts form from dioxane and trimethylamine. … See more Sulfur trioxide (alternative spelling sulphur trioxide, also known as nisso sulfan) is the chemical compound with the formula SO3. It has been described as "unquestionably the most important economically" sulfur oxide. It is prepared … See more Sulfur trioxide undergoes many reactions. Hydration and hydrofluorination SO3 is the anhydride of H2SO4. Thus, it is susceptible to … See more Sulfur trioxide is a reagent in sulfonation reactions. These processes afford detergents, dyes, and pharmaceuticals. Sulfur trioxide is generated in situ from sulfuric acid or is used as a solution in the acid.
