N,N-Di-Sec-Butyl-1,4-Phenylenediamine cas No: CAS Number: 101-96-2

N,N-Di-Sec-Butyl-1,4-Phenylenediamine (CAS 101-96-2) is an aromatic amine used industrially as an antioxidant and polymerization inhibitor. It protects turbine oils, greases, and waxes from heat degradation and stabilizes vinyl monomers like acrylates. It typically appears as a light yellow to dark red liqui

Molecular Formula: C₁₄H₂₄N₂
Molecular Weight: 220.35 g/mol
Synonyms: N,N’-Di-sec-butyl-p-phenylenediamine, Antioxidant 22, Tenamene 2

Its key industrial applications include:
Fuel Stabilization: It is highly effective at preventing the oxidation of olefins in cracked or thermally cracked gasoline. It inhibits the formation of gums, sludge, and undesirable deposits, stabilizing fuels during long-term storage.
Rubber and Polymer Protection: It is used as a universal antiozonant and antioxidant for natural and synthetic rubber products, protecting them from heat, oxygen, and ozone degradation.
Lubricants and Adhesives: It acts as an antioxidant to prevent the degradation of industrial oils (such as turbine and transformer oils), and serves as a chemical intermediate or stabilizer in the formulation of polyurethane adhesives.
