Disodium 4,4'-[({4-[(4-Sulfonatophenyl)Iminio]Cyclohexa-2,5-Dien-1-Ylidene}Methanediyl)Bis(Benzene-4,1-Diylimino)]Dibenzenesulfonate

This is a compound of "disodium 4,4 '- [ ({4- [ (4-sulfophenyl) imino] cyclohexyl-2,5-diene-1-subunit} methylenediyl) bis (benzene-4,1-dimethylamino) ] dibenzenesulfonate". Its chemical structure is complex, including sulfo, imino, cyclohexadienyl, methylenediyl, phenediylamino and many other groups.
In this compound, the sulfonyl group (-SO
) gives it water solubility, which can dissociate ions in aqueous solution, making the molecule hydrophilic. As a nitrogen-containing functional group, the imino group (-NH-) can participate in the formation of hydrogen bonds or other chemical reactions. Cyclohexadienyl is a six-membered cyclic structure with unsaturation, which affects the electron cloud distribution and spatial configuration of the molecule. Hypomethylenediyl (-CH =) plays a role in connecting different benzene ring structures, so that the whole molecule forms a specific conjugate system, which affects its optical and electronic properties. Phenodithiamide is connected to the benzene ring, which further expands the conjugate system and affects the electron delocalization and chemical activity of the molecule.
The overall structure of the compound is connected and interacted with each other through various groups, which determines its physical and chemical properties, such as solubility, stability, reactivity, etc., and may have specific application value in many fields.

This is the disodium salt, the full name is 4,4 '- [ ({4- [ (4-sulfophenyl) imino] cyclohexyl-2,5-diene-1-subunit} methyldiyl) bis (benzene-4,1-dimethylamino) ] dibenzenesulfonate disodium salt. Its physical properties are as follows:
- ** Appearance **: It is often powdery or crystalline, which is caused by the close arrangement and interaction of its molecular structure, just like a finely carved ore.
- ** Solubility **: Shows good solubility in water, because its molecules contain sulfonic acid groups, which are hydrophilic and blend like fish entering water. In polar organic solvents, there is also a certain solubility, but in non-polar organic solvents, the solubility is not good. This is due to polar differences, just like oil and water are difficult to dissolve.
- ** Stability **: Under normal temperature and pressure, the structure is stable, and it is not easy to spontaneously produce chemical changes. It is as stable as a strong fortress. However, in the case of strong acid, strong alkali or high temperature environment, the stability is affected, or the decomposition, hydrolysis and other reactions occur, just like the fortress is shaken by strong earthquakes.
- ** Hygroscopicity **: There is a certain degree of hygroscopicity. Because sulfonic acid can form hydrogen bonds with water molecules, it seems to have the magic power to attract water molecules, so it needs to be properly stored to prevent moisture.

This is a method for the synthesis of disodium 4,4 '- [ ({4- [ (4-sulfophenyl) imino] cyclohexyl-2,5-diene-1-subunit} methyldiyl) bis (benzene-4,1-dimethylamino) ] dibenzene sulfonate. The method is as follows:
First take appropriate raw materials, such as compounds containing sulfophenyl, cyclohexadiene and phenyldiyl structures, and mix them in a delicate ratio according to the ancient method of synthesis. Or in a special kettle, adjust its temperature and control its pressure to make various substances react.
When reacting, be careful to observe its condition, such as the change of color and the movement of temperature. If the temperature is too high, it will decompose the terrorist; if the temperature is too low, the reaction will be delayed. The temperature must be adjusted to get the best effect.
After the reaction is completed, or the method of filtration is used to remove the insoluble matter; or the method of analysis is used to divide the product to be obtained. After the pure method, such as recrystallization, the purity of the product is increased, and the disodium 4,4 '- [ ({4- [ (4-sulfophenyl) imino] cyclohexyl-2,5-diene-1-subunit} methyldiyl) bis (benzene-4,1-dimethylamino) ] diphenylsulfonate. However, the method of synthesis often needs to be fine-tuned according to the actual state to achieve a good state.

This is a disulfonic acid-based disodium salt compound with a long and complicated chemical name. During use, it is necessary to pay attention to the following numbers:
First, safety protection is the key. This compound may have certain chemical activity and latent risk. When operating, be sure to wear suitable protective equipment, such as gloves, goggles and protective clothing, to prevent it from coming into direct contact with the skin and eyes. If inadvertently contacted, rinse with plenty of water immediately and seek medical advice according to the actual situation.
Second, accurately grasp the dosage. Due to the special nature of this compound, the dosage has a great impact on the reaction process and effect. Therefore, before use, it is necessary to accurately determine the dosage according to the specific use and reaction requirements, through rigorous calculation and experimental pre-test, and must not increase or decrease at will, so as not to affect the expected effect.
Third, proper storage should not be ignored. It needs to be stored in a dry, cool and well-ventilated place, away from fire, heat and strong oxidants. Because its chemical structure contains specific groups, improper storage environment or cause it to deteriorate, decompose, and damage its performance.
