NITROUS ACID Chemical compatibility with O-rings, rubbers, & plastics

Nitrous acid (HNO2) is a weak, unstable acid used in various chemical reactions, particularly in diazotization and nitrosation processes. It is typically generated in situ from sodium nitrite and a mineral acid. Nitrous acid is employed in the production of azo dyes, pharmaceuticals, and agrochemicals. Proper handling and storage of nitrous acid are essential to prevent exposure and chemical instability. Safety measures should include the use of personal protective equipment, proper ventilation, and adherence to manufacturer guidelines. Regular monitoring and maintenance of processes using nitrous acid ensure optimal performance and safety, making it a crucial component in chemical synthesis and manufacturing.
