1% 2C10-dibromoanthraquinone has a high melting point, usually above 300 ° C. The high melting point indicates that the intermolecular force is strong, the structure is relatively stable, and a higher temperature is required to destroy the lattice structure and cause it to melt. This property allows the substance to maintain a solid state at general ambient temperature and has good stability. In specific high-temperature industrial processes or chemical reactions, its melting point properties affect the mechanism and manner of its participation in the reaction.
Its density is higher than that of common organic solvents and some inorganic compounds, which is closely related to the type, number and arrangement of atoms in the molecule. The higher density makes it easier to sink or accumulate at the bottom due to gravity in solutions or mixtures. This property affects its distribution and behavior during separation, purification or mixing, providing a basis for related operations.
1% 2C10-dibromoanthraquinone has poor solubility and is difficult to dissolve in water. Due to the weak molecular polarity, the force between water molecules cannot overcome the hydrogen bond between water molecules, so it is not easy to disperse in water. However, in some organic solvents such as dichloromethane, N, N-dimethylformamide (DMF), there is a certain solubility, because the polarity and molecular structure of these organic solvents can interact with 1% 2C10-dibromoanthraquinone to help it dissolve. This solubility characteristic is crucial in synthesis, separation and application, and can be used to select suitable solvents for reaction or purification.
Furthermore, 1% 2C10-dibromoanthraquinone has certain sublimation properties. Although the sublimation temperature is high, it can be directly converted from solid to gaseous under certain conditions. This property provides a unique means for its purification or analysis. It can use the sublimation characteristics to separate impurities and obtain high-purity products.

What is the synthesis method of 1,10-dibromodecane?
The synthesis method of 1,10-dibromoanthraquinone is a wonderful technique in ancient times. In the past, Fang family found the physical properties and clear mechanism, and it was a delicate method.
Take anthraquinone as the base first, which is the key thing. Dissolve it in an appropriate solvent, often selected as benzene, toluene, etc., its mild nature can make anthraquinone disperse evenly.
Then, prepare bromine. Bromine, red brown in color, strong in nature, is an important agent for introducing bromine atoms. Slowly drop bromine into a vessel containing an anthraquinone solution, and control the temperature. If the temperature is too high, the reaction will be too dramatic and prone to clutter; if the temperature is too low, the reaction will be slow and time-consuming. Usually, it is better to control it at a moderate temperature of about forty or fifty degrees.
When dropping bromine, a catalyst needs to be added. Commonly used ones, such as iron filings, ferric chloride, etc. The catalyst can promote the reaction speed and enable the bromine atoms to be precisely in place. Bromine and anthraquinone, with the help of the catalyst, interact, and the bromine atoms rush into the specific parts of the anthraquinone, and then form the initial product of 1,10-dibromoanthraquinone.
However, this product is impure and still contains impurities. Therefore, it needs to be purified by an appropriate method. Use the technique of recrystallization to choose a suitable solvent, such as ethanol, acetone, etc. Dissolve the primary product into a hot solvent, and then slowly cool it to precipitate the crystals. The precipitated crystal is the purer 1,10-dibromoanthraquinone. The impurities are left in the mother liquor and discarded.
In this way, 1,10-dibromoanthraquinone can be obtained by dissolving, dripping, urging and purifying steps. Although this method is ancient, it is clear and correct, and it has been learned by later generations. It also has something to refer to today. It is a classic method in the field of organic synthesis.
What are the precautions for storing and transporting 1,10-dibromodecane?
1% 2C10-dibromoanthraquinone is a valuable chemical raw material. When storing and transporting, many matters need to be paid more attention.
First, the storage place should be in a cool, dry and well-ventilated place. This is because 1% 2C10-dibromoanthraquinone is afraid of moisture, and the humid environment is easy to damage its quality. If the moisture is too heavy, or triggers its chemical reaction, it will affect the purity and performance. And it should be kept away from fire and heat sources. Because of its flammability, it may be dangerous to encounter open flames and hot topics.
Second, the packaging must be tight. Use well-sealed packaging materials to prevent air and moisture from invading. It is commonly packaged in iron or plastic drums. The mouth of the barrel needs to be sealed without gaps to ensure that the material is isolated from the outside world and maintain its stability.
Third, during transportation, the container should be ensured to be stable to avoid collision and vibration. Violent collision or vibration or packaging rupture, material leakage. Once leaked, not only the material is damaged, but also the environment may be polluted. If it is not handled properly, or safety accidents may be caused.
Fourth, it should be stored and transported separately from oxidants, acids, alkalis and other substances. 1% 2C10-dibromoanthraquinone may react chemically with these substances, such as contact with strong oxidants, or cause violent oxidation reactions, endangering safety.
Fifth, the storage and transportation area should be equipped with the corresponding variety and quantity of fire fighting equipment and leakage emergency treatment equipment. In case of fire or leakage accident, it can respond quickly and reduce losses.
In short, the storage and transportation of 1% 2C10-dibromoanthraquinone requires comprehensive consideration from various aspects such as environment, packaging, protection and emergency response to ensure its quality and personnel and environmental safety.
