Sodium-1-amino-9,10-dioxo-4-anilinoanthracene-2-sulfonate, this is an organic compound. Its physical properties are quite critical and often have specific uses in the chemical and materials fields.
Looking at its properties, it is mostly solid under normal conditions, or powdery, or crystalline, which is related to its intermolecular force and crystal structure. Its color often varies according to the content and purity of impurities. The pure one may be white, or yellowish when containing impurities.
Solubility is also an important physical property. In water, its solubility may have a certain solubility due to the polar groups in the molecular structure. The presence of sulfonic acid groups allows the compound to be partially ionized in water, form ions, and then dissolve in water. This property is crucial in the application of some aqueous systems. However, in non-polar organic solvents, such as benzene, toluene, etc., its solubility may be extremely low due to the weak force between the non-polar solvent and the polar structure of the compound.
Melting point is also a key physical parameter. Its melting point is determined by factors such as intermolecular forces, hydrogen bonds, and lattice energy. The specific melting point value needs to be determined by precise experiments, and may vary slightly under different purity and crystalline morphology. Higher melting points suggest that intermolecular forces are strong, the structure is relatively stable, and its own structural integrity may be better maintained in high temperature environments.
In addition, the density of the compound also has a specific value. Although its exact value is affected by many factors, the approximate range can be determined experimentally. The difference in density is an important consideration in operations such as material mixing and separation.
Furthermore, its hygroscopicity cannot be ignored. Due to the existence of polar groups in the molecular structure, it can absorb a certain amount of water in a humid environment or absorb a certain amount of water. This characteristic may affect its storage and use conditions. It needs to be properly preserved to prevent changes in performance due to hygroscopicity.
The physical properties of this compound have a profound impact on its application. In the process of research and development and production, it is necessary to accurately grasp its physical properties in order to achieve its best application effect.

The method of preparing 1-amino-9,10-dioxo-4-phenylaminoanthraquinone-2-sulfonate sodium has followed various delicate techniques in the past. First, choose its source material, the commonly used one, anthraquinone derivatives as the base, supplemented by aniline and other reagents, in order to start the synthesis of the road.
First, make the anthraquinone derivative in a specific reactor, and place it together with an appropriate amount of sulfuric acid, fuming sulfuric acid and other sulfonating agents to control its temperature and time history, and cause the reaction of sulfonation. The degree of sulfonation is related to the quality of the product, and it must be carefully regulated to ensure that the sulfonic acid group is bonded at the 2 position of the anthraquinone ring.
The obtained sulfonation product is the introduction of an amino group. Usually ammonia or amine reagents are used in a suitable medium, or in water or organic solvents. After the amination reaction, the amino group bond is connected to the first position. In this step, the properties of the medium, the temperature, and the pressure are all factors that affect the amination. It is necessary to carefully weigh and make the reaction proceed in the desired direction.
Then the phenylamino group is introduced. With aniline or its derivatives as the source, with the help of catalysis, the phenylamino group is smoothly connected to the fourth position. The catalysts used, either metal salts or organic bases, have their own effects, and should be selected according to the actual situation.
After the reaction is completed, it goes through a series of purification processes, such as crystallization, filtration, washing, etc. When crystallizing, choose a suitable solvent and control the rate of cooling, so that the product can precipitate out with high purity crystals. Filter to remove its impurities, wash it with a pure solvent, remove its unreacted materials and by-products, and finally obtain pure 1-amino-9,10-dioxo-4-phenylaminoanthraquinone-2-sulfonate sodium.
Although this synthesis method has a fixed formula, in practice, it is still necessary to fine-tune various parameters according to the quality of raw materials, the state of equipment, and the calculation of cost.

Sodium + 1 - Amino - 9,10 - Dioxo - 4 - Phenylaminoanthracene - 2 - Sulphonate, this is a chemical substance, which has many points to be paid attention to during use.
First, it is related to safety protection. This substance may be dangerous, and when operating, you must wear appropriate protective equipment. If you wear protective gloves to prevent skin contact, because some of these chemicals may cause allergies, burns and other conditions after contact with the skin. You should also wear goggles to avoid splashing into the eyes. If you are not careful, it is very likely to cause serious damage to the eyes. At the same time, protective clothing is required to protect the body in all aspects.
Second, the use environment is very important. It should be operated in a well-ventilated place to prevent the accumulation of harmful gases. If the substance will release irritating odor or toxic gases during use, good ventilation can discharge it in time to reduce the harm to the human body. And the operation site should be far away from fire and heat sources. Many chemicals can easily cause combustion, explosion and other hazards in case of open flame or high temperature.
Third, access and storage are also exquisite. The access process must be accurate. According to the required dosage, use appropriate equipment to measure. Avoid waste caused by excessive use, and prevent too little use from affecting the experimental or production process. When storing, choose the appropriate conditions according to their characteristics. If some need to be sealed and stored to prevent reactions with oxygen, moisture, etc. in the air; some have requirements for temperature and humidity, and need to be stored in a specific environment, otherwise it may cause material deterioration and affect the use effect.
Fourth, the use process should strictly follow the established specifications. Whether it is used for experimental research or industrial production, there are corresponding standard operating procedures. Change the process at will, or cause problems such as runaway reaction and substandard product quality. After use, the remaining substances and waste should be properly disposed of and should not be discarded at will to prevent environmental pollution.
