The addition process must be slow, and at the same time, gentle stirring will promote uniform mixing to make the reaction start smoothly. < Br >
The reaction temperature is also a key factor. The reaction system can be gradually warmed up to a specific range. This range needs to be carefully explored according to the specific reaction conditions. Generally speaking, it is controlled at a moderate temperature, such as around [X] ° C. If it is too high, it is easy to cause side reactions, and if it is too low, the reaction rate will be low. During the heating process, it is necessary to pay close attention to the process of the reaction, observe its color, state and other changes, and use this as a basis to fine-tune the temperature and reaction time.
The reaction time cannot be ignored, and the optimal time must be determined through multiple tests to ensure that the reaction is sufficient and does not cause excessive reaction.
