22607-32-5 - Introduction
2-(2H-Benzotriazol-2-yl)-5-[(2-ethylhexyl)oxy]phenol is a chemical substance, also known as UV-329. It has the following properties:
1. Appearance: white crystal or crystalline powder.
2. Molecular formula: C20H25N3O2.
3. Molecular weight: 339.43g/mol.
4. Melting Point: 84-88 ° C.
5. Solubility: Soluble in most organic solvents, such as ethanol, acetone, etc.
UV-329 are mainly used as ultraviolet absorbers, which can be used to prevent material aging and color changes caused by light. It is often added to plastic products, paints, coatings, polymers, rubbers, fibers and glues to improve the light resistance and oxidation resistance of these materials.
The method for preparing UV-329 can be obtained by transesterification of benzyl triphenylphosphonate with 2-aminophenol. The specific preparation method can refer to the relevant literature or patent.
When using or handling UV-329, you need to pay attention to the following safety information:
1. Please operate in a well-ventilated place, avoid inhalation or contact with skin and eyes.
2. Avoid reaction with strong oxidants.
3. Wear appropriate personal protective equipment, including goggles, gloves and protective clothing.
4. Do not eat, drink or smoke during treatment.
5. In case of accidental contact or inhalation, rinse immediately with water and seek medical help.
