In the past, to make this substance, first use benzophenone as the base material and place it in a specific reactor. An appropriate amount of sulfuric acid is added to the kettle, and the concentration and dosage of sulfuric acid are carefully calculated to ensure that it can effectively promote the reaction. Sulfuric acid is like a wise guide in this reaction, leading the gradual transformation of benzophenone molecules.
When the reaction is carried out, the temperature needs to be precisely controlled. If the temperature is too high, the reaction will be too fast, and impurities will be feared; if the temperature is too low, the reaction will be slow and time-consuming. Therefore, a moderate heat is often used to maintain the temperature in the kettle within a certain range, so that the reaction is smooth and orderly.
As the reaction progresses, the reaction process is closely monitored. Various analytical methods can be used, such as chromatographic analysis, to observe the composition changes. When the reaction reaches the expected level, follow-up treatment is carried out.
