Its color and state are quite useful in the preliminary understanding of this thing, and it can be roughly known by sight.
The second time its boiling point is about 240-242 ° C. The boiling point is also the temperature limit for the substance to change from liquid to gas. This boiling point value indicates that in order to gasify 4- (tert-butyl) iodobenzene, this temperature range is required. At this temperature, the molecule is sufficiently energized to break free from the liquid phase and escape into the gas phase.
Furthermore, the melting point is also a key physical property. Its melting point is about -25 ° C, which means that the temperature drops to -25 ° C and below, and 4- (tert-butyl) iodobenzene will gradually change from liquid to solid. The level of melting point affects its physical form under different temperature environments.
The density of 4- (tert-butyl) iodobenzene is about 1.45g/cm ³. The density is also the mass of the substance per unit volume. This density value can help to judge the floating and sinking condition when it is mixed with other substances, and is of great significance in chemical operations, separation and purification processes.
In terms of solubility, 4- (tert-butyl) iodobenzene is insoluble in water, but it can be soluble in common organic solvents such as ethanol, ether, benzene, etc. This solubility characteristic is extremely important in the fields of organic synthesis, extraction and separation, and can be used to select suitable solvents to achieve specific chemical purposes.
Its vapor pressure has a specific value at a specific temperature, although it is not detailed, but the vapor pressure is related to its volatilization difficulty. The higher the vapor pressure, the more volatile the substance is under the same conditions. Pay attention when storing and using it to prevent losses or safety hazards caused by volatilization and dissipation. The physical properties of 4- (tert-butyl) iodobenzene have their own uses and are an indispensable consideration in many aspects such as chemical production, organic synthesis, and scientific research.

To prepare 4 - (tert-butyl) iodobenzene, the following method can be used.
First take benzene as the starting material, make benzene and tert-butyl chloride under the catalysis of anhydrous aluminum trichloride, Fu-gram alkylation reaction. In this reaction, the chlorine atom of tert-butyl chloride is polarized by aluminum trichloride to form a tert-butyl carbon positive ion, which attacks the benzene ring as an electrophilic reagent and replaces the hydrogen atom on the benzene ring to obtain tert-butyl benzene. During the reaction, the temperature should be controlled within a certain range, and the equipment used should be dried to avoid
Next, tert-butylbenzene and iodine are heated in an organic solvent in the presence of an appropriate amount of catalyst such as cuprous iodide and ligands, and an appropriate base such as potassium carbonate is used as an acid binding agent. During this process, iodine undergoes electrophilic substitution of the para-position of tert-butylbenzene under the action of the catalyst to generate 4- (tert-butyl) iodobenzene. The reaction system needs to be carried out under the protection of inert gas to prevent iodine and its products from being oxidized. After the reaction is completed, the relatively pure 4- (tert-butyl) iodobenzene can be obtained through post-treatment steps such as extraction, washing, drying, and distillation. In this way, the required 4- (tert

For 4 - (tert-butyl) iodobenzene, there are several ends that should be added when storing and transporting.
First storage environment. This material or more sensitive, should be placed in a cool, dry and well-ventilated place. Avoid open flames and hot topics to prevent accidental explosion. If it is in a warm and humid environment, or causes its qualitative change, it will damage its inherent properties. And it needs to be separated from oxidants, strong alkalis, etc., because of it, it may cause severe reactions, endangering safety.
Times and packaging. Tight and suitable packaging materials must be used. Common such as glass bottles, wrapped in thick paper, or packaged in plastic drums. However, the selected packaging must be resistant to its corrosion and prevent the risk of leakage. The label of the packaging, the name, nature, and danger level of the statement, etc., are easy to identify and avoid accidental touch and misuse.
When transporting, also pay more attention. Those who choose qualified transporters should be familiar with their properties and transportation regulations. Drive slowly on the way to avoid bumps and shocks, and prevent package damage. During the summer heat, you should be especially careful about high temperatures, and you can use appropriate methods to cool down. If the transportation time is long and long, check the packaging when it is finished, and there will be any leaks.
In addition, where it is stored and transported, it is necessary to have corresponding emergency materials, such as fire extinguishers and leaks. When the staff knows the emergency method, they can respond quickly in case of danger and reduce the damage to a minimum. In this way, the safety of 4- (tert-butyl) iodobenzene in storage and transportation is guaranteed.

4 - (tert-butyl) iodobenzene is also an organic compound. Its impact on the environment and human health cannot be underestimated.
On the one hand of the environment, such compounds are difficult to degrade if they enter the natural environment. They may remain in the soil for a long time, hindering the balance of the soil ecosystem. Due to their stable structure, it is difficult for microorganisms to decompose them effectively. If they flow into water bodies, they will also pose a threat to aquatic organisms. After aquatic organisms are exposed to this substance, they may experience physiological disorders, such as growth retardation, decreased reproductive ability, etc. This is because the compound may interfere with the normal biochemical reactions in organisms, affect hormone balance, enzyme activity, etc.
As for human health, 4- (tert-butyl) iodobenzene is also potentially harmful. After entering the human body through breathing, skin contact or accidental ingestion, or accumulating in the body. Studies have shown that such organic iodine compounds may affect the human endocrine system. The endocrine system is related to the regulation of many physiological functions of the human body. Once disturbed, thyroid function may be abnormal. The synthesis and secretion of thyroid hormones are affected, which in turn affects metabolism, growth and development. And it may cause genetic mutations, long-term exposure may increase the risk of cancer and other diseases. When skin contact, it may cause skin problems such as allergies and inflammation; if inhaled its volatile gaseous substances, the respiratory tract will also be irritated, and uncomfortable symptoms such as cough and asthma will appear.
In conclusion, 4- (tert-butyl) iodobenzene poses a potential threat to both the environment and human health, and it needs to be treated with caution to prevent its wanton spread in order to ensure the safety of the ecological environment and human health.
