According to its physical properties, researchers can reasonably choose reaction conditions, separation and purification methods.
    What is the chemical synthesis method of 4-iodobenzonitrile?
    The synthesis method of 4-iodobenzonitrile, although the ancient book "Tiangong Kaizhi" does not detail the synthesis method of this specific compound, can be deduced from the ancient chemical process ideas.
    In the past, halides were often reacted with corresponding aromatic hydrocarbons with halogenating agents. To obtain 4-iodobenzonitrile, benzonitrile can be taken as the substrate and iodide as the iodine source. In ancient times, potassium iodide was used as the iodine source, but it can also be used today. Choose a suitable catalyst, such as a copper-based catalyst, and copper salts are often the choice of catalysis in organic synthesis in the past, whereby iodine atoms and benzonitrile can be promoted. When
    reacts, the reaction temperature and time need to be controlled. In the ancient process, temperature control is related to the effectiveness of the reaction. The reaction may be at a moderate temperature, such as tens of degrees Celsius to 100 degrees Celsius, to ensure a smooth and efficient reaction. The time also needs to be adjusted. If it is too short, the reaction will not be complete, and if it is too long, it will cause side reactions.
    can also be prepared by cyanylation of 4-halobenzene. Take 4-halobenzene first, such as 4-chlorobenzene or 4-bromobenzene, and use a cyanide reagent. In the past, potassium cyanide was used to replace the halogen atom with a cyanide group. However, potassium cyanide is highly toxic, so be careful when using it. In operation, 4-iodobenzonitrile can be obtained by mixing appropriate proportion of reactants in a suitable solvent, catalyzing it, and controlling temperature in a timely manner.
    In general, using ancient chemical ideas and operations, select substrates, iodine sources, cyanide reagents, and control temperature, time, and ratio to achieve the purpose of synthesizing 4-iodobenzonitrile.

    What is the market price range for 4-iodobenzonitrile?
    4-Iodobenzonitrile is also an organic compound. The market price often varies depending on the purity of the product, supply and demand, and the place where it is produced.
    Looking at the market, the price may hover between a few yuan and tens of yuan per gram. If it is of ordinary purity, the price may be lower; if it is of high purity, it is especially suitable for precision research and specialty industries, and the price is higher.
    In the past, due to sufficient supply and lack of demand, the price became stable and low. However, chemical and pharmaceutical research and development are on the rise, and their demand is gradually increasing, causing the price to rise. The lack of production, or the price change of raw materials, can also lead to the price of 4-iodobenzonitrile.
    At some time, due to the new high-efficiency method of the first producer, the output increased greatly, and the price fell. Later, he used this product to increase, seeking excess supply, and the price rose again. Therefore, its market price often ranges from a few yuan per gram to tens of yuan per gram, and it is difficult to determine the exact number, all due to the variety of market conditions.
