UV absorber UV-2908 Chemical Properties,Usage,Production

Physical properties

Hexadecyl 3,5-di-tert-butyl-4-hydroxybenzoate (UV Absorber 2908) is white to faint yellow powder. The specific gravity is 1.07 at 25℃. It is easy soluble in toluene, chloroform, hexane, soluble in acetone etc.

Uses

DXSORB 2908 (Hexadecyl 3,5-di-tert-butyl-4-hydroxybenzoate; UV Absorber 2908) is an excellent light stabilizer, low volatility, small coloring, good chemical stability, acid and alkali resistance. Suitable for PP and PE and other polyolefin plastics, the general dosage of 0.25 ~ 0.1%. This product can be used alone or in combination with benzophenone ultraviolet stabilizer or phosphite antioxidant, showing good synergistic effect.

Uses

The product belongs to the class of hindered hydroxybenzoate light stabilizer. UV-2908 is most suitable for the protection of polyolefins, polycarbonate and the systems containing flame retardants and thioesters. It can be used alone or in combination with benzophenone UV stabilizer or phosphite antioxidant, showing good synergistic effect.The dosage of UV-2908 ranges between 0.25% and 1% are recommended for protection. It depends on the substrate and performance requirement of the final application.

benefits

Low volatility, minimal color contribution, good chemical stability, acid and alkali resistant, excellent compatibilty with UV absorbers, HALS, and thioesters, FDA sanctioned to 0.5% in polyolefins

Flammability and Explosibility

Not classified

Safety

In accordance with good industrial practice, handle with care and avoid unnecessary personal contact. Avoid continuous or repetitive breathing of dust. UV Absorber 2908 is used only with adequate ventilation. Avoid dust formation and ignition sources.

Synthesis

1.Add 3,5-di-tert-butyl-4-hydroxybenzoic acid (3.03 g), 1-hexadecanol (4.42 g), toluene (30 ml) and dried ion-exchange resin (1.49 g, 20 wt%) into a two-necked round flask equipped with a magnetic stirrer for 11.5 hours.2.High performance liquid chromatography is adopted to monitor the reaction and determine the component of the reaction mixture.
