2-Benzotriazol-1-yl-propionic acid - Introduction
btpa (btpa) is an organic compound with the chemical formula C10H9N3O2. The following is a description of its nature, use, preparation and safety information:
Nature:
-Appearance: White crystalline solid
-melting point: 160-163 ℃
-Solubility: Soluble in polar organic solvents such as chloroform, methanol and dimethyl sulfoxide
Use:
- BTPA is primarily used as a UV absorber. It can absorb ultraviolet light and reduce the impact of light on materials such as organics, coatings, paints and plastics, thereby extending their service life and stability.
-In addition, BTPA can also be used as a metal corrosion inhibitor, a synthetic raw material for dyes, a high-temperature stabilizer, and a fluorescent whitening agent.
Preparation Method:
-A commonly used preparation method is obtained by the condensation reaction of p-benzoic acid and phenyltriazole. The specific steps include reacting benzoic acid with triethylamine under acidic conditions to generate an intermediate benzoyl triethylamine, and then reacting with phenyltriazole in dichloromethane to finally obtain BTPA.
Safety Information:
-The specific hazards of BTPA have not been clearly determined, but as a chemical, routine operating procedures and safety precautions should be followed.
-When operating, you must wear protective glasses and gloves, and ensure that the operating area is well ventilated.
-Avoid contact with skin and eyes. In case of contact, rinse immediately with water for at least 15 minutes and seek medical help.
-During storage and transportation, BTPA should be kept away from open flames and heat sources, and stored in a dry, cool place.
Please note that the above information is for informational purposes only and the specific nature, use, formulation and safety information may require further experimental validation and professional guidance.
