GENERAL DESCRIPTION & APPLICATIONS

Diphenylamine is used as a parent compound for vulcanization accelerators and for antioxidants (and antiozonant) for rubber industry. These derivatives are added to rubber products to retard degradation by oxidants and ozone. They are intermediates for the production of dyes, pH indicators, polymers and fibers, and curing agents, a test for oxidizing agents and in detecting DNA in labs. Diphenylamine is used to absorb decomposed catalysts in solid fuel rocket propellant.
