General description

2-(2H-Benzotriazol-2-yl)-4,6-di-tert-pentylphenol (UV-328) is an ultraviolet (UV) stabilizer with a phenolic group connected to the benzotriazole structure. These phenolic groups facilitate the absorption of UV light. UV-328 is mainly used in as a light stabilizer for coating and as an additive for industrial polymers.

Application

UV-328 is a class of benzotriazole derivatives that can potentially be used as corrosion inhibitors in heat resistant fluids in aircraft, brake fluids in automobiles and for other industrial cooling systems.

Optical patterns are produced on the surface of drawn linear polyethylene containing 2-(2H-benzotriazol-2-yl)-4,6-ditertpentylphenol (BZT), a photothermal dye, by direct laser writing. The photothermal dye absorbs the UV light and dissipates heat in the polyethylene film. This heat locally results in

The first method for the determination of commonly used corrosion inhibitors in environmental water samples by liquid chromatography-electrospray ionization-tandem mass spectrometry is presented. Benzotriazole (BTri) and the two isomers of tolyltriazole (5- and 4-TTri) are separated in an isocratic run.
