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

Dry sulfur trioxide (SO3) is a colorless to white crystalline solid 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 dry 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 dry sulfur trioxide. Its effectiveness in the production of sulfuric acid and its role in sulfonation make dry sulfur trioxide a valuable chemical in numerous industrial applications, although its use requires careful control to prevent health and environmental hazards.
