| titleOfInvention | A kind of preparation method of benzophenone |
| abstract | The invention provides a preparation method of benzophenone. The preparation method comprises the following steps: reacting benzoic acid, trichlorotoluene and benzene under the catalysis of Fe 2 O 3 to obtain the benzophenone. The preparation method provided by the invention obtains the target product through a one-step reaction, the reaction conditions are mild, the process is simple, and the cost of equipment investment, energy consumption and labor required for production is reduced ; O 3 is used as a catalyst to avoid the corrosion of materials to equipment, and the negative impact on field operators and the environment is significantly reduced, making it more environmentally friendly; a small amount of by-product benzoic acid generated by the reaction can be washed, extracted and desolventized in the post-treatment process. The method is recycled, and then used as a reaction raw material for the preparation of benzophenone, which reduces the cost of wastewater treatment and makes full use of resources. |
