Quality:
4,4′-Dimethoxybenzophenone is a colorless to pale yellow liquid with the aroma of benzene. It is flammable, has a higher density, and dissolves in common organic solvents such as ethanol, ethers, and ketones. It is unstable to air and light and can undergo oxidation reactions.
Use:
4,4′-dimethoxybenzophenone is often used as a catalyst or reagent in organic synthesis and has high activity. In organic synthesis, it can be used in the preparation of aldehydes, ketones, etc.
Method:
The preparation method of 4,4′-dimethoxybenzophenone can be achieved by the condensation reaction of dimethoxybenzosilane and benzophenone. Dimethoxybenzosilane is reacted with sodium borohydride to obtain boranol, and then condensed with benzophenone to obtain 4,4′-dimethoxybenzophenone.
Safety Information:
4,4′-Dimethoxybenzophenone is irritating to the skin and may cause irritation of the eyes and respiratory tract. Appropriate protective measures such as gloves, goggles, and respirators should be worn during handling and use. During storage, it should be kept in a cool, dry place, away from ignition and oxidants. Please follow safe operating procedures and follow all relevant regulations and requirements.
