Method of making iodized benzene
To make iodized benzene (Iodobenzene Bp), first take an appropriate amount of benzene and place it in a clean reactor. The kettle must be dry and well sealed to prevent impurities from mixing.

Prepare an appropriate amount of iodine and slowly add it to the kettle containing benzene. At the same time, add a little catalyst, this catalyst can promote the reaction to accelerate. Copper powder and the like are commonly used. The dosage should be precisely controlled. Too much or too little may affect the reaction effect.

After that, heat the reactor moderately and control the temperature to a suitable range. The heating process should pay attention to the stable heat, and do not cause the temperature to rise too quickly. When the reaction continues for a period of time, it can be seen that there are signs of new substances in the kettle.

After the reaction is completed, the product is separated and purified. The distillation method can be used to collect the fraction at a specific temperature according to the boiling point characteristics of iodobenzene iodide (Iodobenzene Bp), which is a relatively pure iodized benzene. The whole process requires careful operation and strict compliance with procedures to obtain the desired result.
