2,2'-Methylenebis(4-methyl-6-tert-butylphenol)

Advantages

Antioxidant 2246 is a versatile, powerful hindered phenolic-aldehyde antioxidant with wide applications. It is non-polluting, non-toxic, and non-coloring to products, and provides excellent protection against heat, oxygen, and cracking aging.

Applications

Antioxidant 2246 is a versatile, highly effective, and non-polluting antioxidant widely used in synthetic resins, synthetic rubber, and natural rubber. It exhibits excellent resistance to thermo-oxidative aging, preventing discoloration and blooming in finished products.

This is a general-purpose phenolic antioxidant, widely used in natural rubber, synthetic rubber, latex, and various other synthetic materials and petroleum products as an antioxidant. The typical dosage is 0.10-1.5%. This product is a widely used phenolic antioxidant suitable for various plastics, ABS, AS, and natural rubber. Antioxidant 2246 is a general-purpose, high-strength bisphenol antioxidant, widely used in natural rubber, various synthetic rubbers, polyethylene, polypropylene, polyoxymethylene, ABS resin, chlorinated polyether, polyurethane, and other synthetic materials. Antioxidant 2246 features high thermal stability, good antioxidant effect, non-polluting, non-coloring, non-blooming, good oil solubility, low volatility loss, no effect on rubber vulcanization and plasticity, no instability to latex, and low dosage.

Synthesis Method

Using hydrochloric acid as a catalyst and n-heptane as an inert organic solvent, 2-tert-butyl-4-methylphenol reacts with formaldehyde at temperatures below 60°C. The reaction equation is as follows:
