Technical Field

[0001] The utility model relates to the technical field of benzophenone preparation, in particular to a device for preparing benzophenone and benzophenone derivatives. Background Art

[0002] Benzophenone, also known as benzophenone and dibenzophenone, is an organic compound with the chemical formula C13H10O. It is mainly used as a fragrance fixative, ultraviolet absorber, styrene polymerization inhibitor, photocuring agent, gas chromatography stationary liquid, and can also be used in organic synthesis. For example, the patent subject "A high-purity benzophenone preparation device" with application number "201721224557.9" can adjust the reaction temperature during the preparation of benzophenone by setting the insulation tank to improve the preparation efficiency.
