Preparation of Chloro benzene: add dry benzene into chlorination reactor. Then add 1% iron as catalyst and add gaseous chlorine to maintain the reaction temperature at 40~60 °C. After the chlorination reaction, add 10% NaOH to the chloride material. At last, product is obtained by dry and distillation.
Uses of Chloro benzene: it is used as intermediate of dye, medicine, pesticide and organic synthesis. It's also used to produce solvent, rubber chemical, paint, quick-drying ink, dry cleaning and so on. Besides, this chemical is used in test of electronic industrial products and raw materials.
When you are using this chemical, please be cautious about it. As a chemical, it is highly flammable and has danger of very serious irreversible effects through inhalation, in contact with skin and if swallowed. During using it, wear suitable protective clothing and gloves. What's more, avoid contact with skin and eyes and avoid release to the environment. In case of accident or if you feel unwell seek medical advice immediately.
You can still convert the following datas into molecular structure:
