106359-89-1 - Introduction
2-Trimethylsiloxy-4-allyloxybenzophenone, chemical formula C22H26O2Si, is an organosilicon compound.
Nature:
2-Trimethylsiloxy-4-allyloxybenzophenone is a colorless to light yellow solid with good thermal stability and solubility. It is soluble in many organic solvents, such as ethanol, dimethyl ether and chloroform. It is stable in the air, but should avoid prolonged exposure to sunlight.
Use:
2-Trimethylsiloxy-4-allyloxybenzophenone is commonly used as a photoinitiator, especially in light-curable polymers. It can absorb ultraviolet light and convert it into energy that can initiate a photosensitive reaction, thereby promoting the curing of the polymer. Because of its excellent thermal stability and light absorption properties, it is widely used in coatings, adhesives, paints and plastics industries.
Preparation Method:
The preparation of 2-trimethylsiloxy-4-allyloxybenzophenone is mainly carried out by organic synthesis methods. The specific preparation method can be selected according to different synthetic routes, and a common method is the reaction of trimethylmagnesium silicate and 2-bromoacetone, and then the target product is obtained by condensation reaction with benzophenone under alkaline conditions.
Safety Information:
2-trimethylsiloxy-4-allyloxybenzophenone has low toxicity, but it is still necessary to pay attention to safe operation. During use, direct contact with skin and eyes should be avoided, and personal protective equipment should be worn if necessary. Avoid prolonged exposure to the sun to avoid adverse reactions. Keep away from open flames and other flammable substances during storage and handling. In addition, storage, transportation and handling shall be carried out in accordance with relevant regulations and guidelines. Correct laboratory procedures and safety practices should be followed when using. In case of contact or accidental ingestion, seek medical attention immediately.
