Description

tert-Butylcatechol CAS NO 27213-78-1 is a specialized phenolic compound widely used as a highly effective polymerization inhibitor and antioxidant in industrial processes. Its primary value lies in preventing premature polymerization of monomers such as styrene, butadiene, and acrylics during storage, transportation, and distillation, thereby ensuring process safety and product stability. This chemical is essential for manufacturers in the petrochemical, polymer, resin, and adhesive industries who require reliable stabilization of reactive intermediates and finished products.

Application

• Polymerization Inhibitor: Primary use as a stabilizer to prevent unwanted polymerization of vinyl monomers (e.g., styrene, acrylates) during production, purification, and storage.
• Antioxidant for Fuels and Oils: Added to gasoline, jet fuels, and lubricating oils to inhibit gum formation and oxidative degradation, extending shelf life and performance.
• Intermediate for Specialty Chemicals: Serves as a key building block in the synthesis of more complex antioxidants, UV stabilizers, and pharmaceutical agents.
• Stabilizer for Unsaturated Polyester Resins: Prevents gelation during the storage of resin precursors used in fiberglass and composite materials.
• Inhibitor in Adhesive Formulations: Used in acrylic- and styrene-based adhesives to maintain viscosity and pot life.
• Additive in Photographic Chemicals: Acts as a developing agent stabilizer in certain photographic solutions.
