Abstract
The invention provides a preparation method of 4-iodobiphenyl, belonging to the field of organic chemical synthesis. According to the preparation method, the technical problems that a product of a traditional synthesis method is low in purity, poor in appearance and color and tedious and complex to separate and purify are solved. By virtue of the method for synthesizing high-purity 4-iodobiphenyl by introducing a novel Cu-La silicon dioxide mesoporous composite catalyst into iodination reaction of biphenyl, the technical problems are solved. A new method having the advantages of low cost and pollution and high purity and selectivity is provided for the industrial production of liquid crystal material intermediate 4-iodobiphenyl.
