What is Fuming Sulfuric Acid?

Fuming sulfuric acid, also known as oleum, is a highly reactive form of sulfuric acid that contains free sulfur trioxide (SO3). Its elevated reactivity makes it indispensable for processes that require aggressive oxidation or high‑temperature reactions, such as the manufacture of high‑grade fertilizers, polymerization catalysts, and semiconductor etchants. The acid’s unique properties allow manufacturers to achieve higher yields and purities in a shorter time frame, which translates into cost savings and competitive advantage.
