1%2C1%27-oxybis%284-iodobenzene%29 that is, 1,1 '-oxo-bis (4-iodobenzene), the physical properties of this substance have the following numbers.
View its shape, under room temperature, 1,1' -oxo-bis (4-iodobenzene) is often white to light yellow crystalline powder, like fine grains, gathered in piles, under sunlight, slightly flooded, just like fine salt and slightly different color.
On its melting point, the melting point is about 138-142 ° C. When the temperature gradually rises, the substance begins to slowly melt from solid to liquid, like ice and snow melting with warmth. As for the boiling point, because the substance is easily decomposed by heat, there is no exact boiling point to speak of. Before the decomposition temperature is reached, chemical changes have taken place and decomposed into other substances.
Its solubility is also an important physical property. 1,1 '-Oxydibenzene (4-iodobenzene) is insoluble in water. When placed in water, it is like gravel entering water, with distinct particles. It sinks to the bottom of the water and rarely dissolves. However, in organic solvents, it has different performances. It can be soluble in organic solvents such as dichloromethane, chloroform, and toluene, which can be uniformly dispersed to form a uniform solution, just like sugar dissolves in water, and it is integrated.
In addition, the density of 1,1 '-oxobis (4-iodobenzene) is greater than that of water. If it is put into water, it will sink to the bottom. And its stability is acceptable. In the conventional temperature and humidity environment, it can maintain the stability of its own structure and properties. In case of extreme conditions such as high temperature, strong acid, and strong alkali, it will also react, causing its structure and properties to change.

1%2C1%27-oxybis%284-iodobenzene%29 is 1,1 '-oxobis (4-iodobenzene), which is an organic compound. Its chemical properties are quite unique, let me explain them one by one.
First of all, the compound has a certain stability. Due to the existence of benzene ring structure, the benzene ring conjugation system endows it with relatively stable properties. However, the presence of iodine atoms in its molecules makes the reactivity of compounds different. Iodine atoms can participate in a variety of chemical reactions, and can undergo nucleophilic substitution reactions due to their electronegativity and atomic radius. For example, when suitable nucleophiles exist and the conditions are suitable, iodine atoms can be replaced by nucleophiles, thereby forming new carbon-heteroatomic bonds, which is of great significance for the synthesis of new organic compounds.
Furthermore, the solubility of 1,1 '-oxobis (4-iodobenzene) also has characteristics. Generally speaking, it has a certain solubility in organic solvents such as dichloromethane, chloroform, toluene, etc. Because the compound is an organic molecule, it follows the principle of similar miscibility, and the intermolecular force with the organic solvent makes it soluble in it. However, the solubility in water is not good, because the polarity of water molecules is strong, and the intermolecular force with the organic compound is weak, so it is difficult to dissolve.
In addition, from the perspective of spectral properties, it has a characteristic absorption peak in the infrared spectrum. The skeleton vibration of the benzene ring and the vibration of the C-I bond all produce corresponding absorption peaks, which can be used to characterize its structure. In nuclear magnetic resonance spectroscopy, hydrogen and carbon atoms in different chemical environments will exhibit specific chemical shifts, providing a strong basis for determining the molecular structure.
1,1 '-oxobis (4-iodobenzene) Due to the properties of iodine atoms and benzene rings in the structure, it may have potential applications in organic synthesis, materials science and other fields. It can be used as a synthesis intermediate to participate in many reactions, laying the foundation for the preparation of more complex organic compounds.

1% 2C1% 27 - oxybis% 284 - iodobenzene% 29 is 1,1 '-oxydi (4 - iodobenzene), the following is the synthesis method:
To prepare 1,1' -oxydi (4 - iodobenzene), 4 - iodophenol is often used as the starting material. First, 4 - iodophenol is mixed with a suitable base, such as sodium hydroxide or potassium carbonate, in a suitable solvent, such as N, N - dimethylformamide (DMF) or dimethyl sulfoxide (DMSO). The base can capture the hydrogen of the 4 - iodophenol hydroxyl group to form phenoxanion. < Br >
Then, add an appropriate halogenated hydrocarbon, such as 4-iodobromobenzene. Phenoxy negative ions nucleophilically attack the carbon connected to the halogen atom of 4-iodobromobenzene, and a nucleophilic substitution reaction occurs. After this step, a carbon-oxygen bond can be formed, resulting in 1,1 '-oxydi (4-iodobenzene).
During the reaction process, it is necessary to pay attention to the control of the reaction temperature and time. If the temperature is too low, the reaction rate will be slow; if the temperature is too high, side reactions may occur. Generally speaking, the reaction temperature can be controlled between 50 and 100 ° C, and the reaction time varies from a few hours to ten hours, depending on the specific
In addition, after the reaction is completed, the separation and purification of the product is also critical. The column chromatography method is often used to select a suitable eluent, and the product is separated and purified from the reaction mixture to obtain a purified 1,1 '-oxybis (4-iodobenzene). In this way, it can be synthesized into 1,1' -oxybis (4-iodobenzene).

1% 2C1% 27 - oxybis% 284 - iodobenzene% 29 is 1,1 '-oxybenzene (4 - iodobenzene). When using this product, many things need to be paid attention to.
Bear the brunt, safety is the key. This is a chemical substance, or toxic and irritating. When taking it, be sure to wear appropriate protective equipment, such as gloves, goggles and lab clothes, to prevent it from coming into contact with the skin and eyes. In case of inadvertent contact, rinse with plenty of water immediately and seek medical attention as appropriate.
Furthermore, its chemical properties cannot be ignored. 1,1' -oxybenzene (4 - iodobenzene) under specific conditions, or participate in chemical reactions. When storing, it should be placed in a dry, cool and well-ventilated place, away from fire sources and oxidants to avoid danger. During use, the reaction conditions should be precisely controlled, such as temperature, pH and reaction time, to ensure that the reaction proceeds as expected and avoid side reactions.
In addition, the operating environment is also very important. The use site needs to be well ventilated to prevent the accumulation of harmful gases. If operating in the laboratory, follow the laboratory rules and regulations and safety procedures. At the same time, the remaining substances and waste after use should be properly disposed of according to regulations, and should not be discarded at will to prevent pollution to the environment.
In conclusion, the use of 1,1 '-oxybenzene (4-iodobenzene) requires constant caution and strict adherence to safety regulations and operating procedures to ensure personnel safety and smooth experimentation.
