UV 327 Use and Manufacturing

Methods of Manufacturing

The p-chloro-o-nitroaniline is diazotized with sodium nitrite, and then coupled with 2, 4-di-tert-butylphenol. The coupling product is reduced by adding zinc powder in an alcohol-alkali medium to obtain a crude product, and then to be purified to obtain a finished product. Raw material consumption (kg/t) phenol (99%) 2201 isobutylene (99.5%) 2615 (used to synthesize 2, 4-di-tert-butylphenol) p-chloro-o-nitroaniline (60%) 2044 ethyl acetate (98% ) 6765 (for purification)

Uses

Excellent light stabilizer, good synergistic effect when used with antioxidant. The product has low volatility and good compatibility with resin. It is suitable for polypropylene, polyethylene, polyoxymethylene and polymethyl methacrylate, etc., especially for polypropylene fiber. Especially suitable for polyethylene and polypropylene, but also for polyoxymethylene, polymethyl methacrylate, polyurethane and various coatings
