SULFUR TRIOXIDE Chemical compatibility with O-rings, rubbers, & plastics

Sulfur trioxide (SO3) is a colorless to white crystalline solid or liquid, depending on temperature, used primarily in the production of sulfuric acid, one of the most important industrial chemicals. It is also employed in the sulfonation of organic compounds, making it valuable in the production of detergents, dyes, and pharmaceuticals. Proper handling and storage of sulfur trioxide are essential to prevent accidents and ensure safety, as it is highly reactive and can cause severe burns and respiratory irritation. Safety measures, including the use of appropriate protective equipment and adherence to handling protocols, are crucial when working with sulfur trioxide. Its effectiveness in the production of sulfuric acid and its role in sulfonation make sulfur trioxide a valuable chemical in numerous industrial applications, although its use requires careful control to prevent health and environmental hazards.
