What are the physicochemical properties of Trisodium 7-Hydroxy-8- ((4- (1- (1-Hydroxy-4-Sulphonato-2-Naphthyl) Azo) Phenyl) Cyclohexyl) Phenyl) Azo) Naphthalene-1,3-Disulphonate?
This is a complex organic compound called trisodium-7-hydroxy-8- [ (4- (1- (4- ((1-hydroxy-4-sodium sulfonate-2-naphthyl) azo) phenyl) cyclohexyl) phenyl) azo] naphthalene-1,3-disulfonate. Its physicochemical properties are quite important and related to many fields of application.
First of all, solubility, this compound has good water solubility because it contains multiple sulfonic acid groups. The sulfonic acid group is a strong hydrophilic group that can form hydrogen bonds with water molecules, resulting in the substance being easily soluble in water and forming a uniform solution in water. This property makes it extremely convenient for the application of aqueous systems, such as water-based coatings, printing and dyeing aids, etc., which can be well dispersed and dissolved to exert its due effect.
Besides stability, there are multiple conjugated systems in the molecular structure, including naphthalene ring, benzene ring and azo structure. The conjugated system can reduce the molecular energy and enhance the stability of the molecule. However, the azo structure is relatively active and may decompose or undergo structural changes under light, high temperature or specific chemical environments. For example, when exposed to strong light for a long time, the azo bond may break, causing the compound to change color or lose its original function.
In terms of acidity and alkalinity, the hydroxyl group can exhibit acidity under certain conditions due to the presence of hydroxyl groups and sulfonate groups in the molecule, while the sulfonate group is weakly basic. Overall, its acidity and alkalinity will be affected by the pH of the environment in which it is located. In an acidic environment, the sulfonate group may be protonated, changing its solubility and chemical activity; in an alkaline environment, the hydroxyl group may undergo deprotonation, which also affects the properties of the compound.
The chromaticity of this compound is also worthy of attention, due to the large number of conjugated systems and chromophores in the molecule, such as azo structures, which give it a specific color. The conjugated system can absorb visible light of a specific wavelength, resulting in color. It can be used as a dye in the dye industry to dye fabrics and the like using its color characteristics.
What is the synthesis method of Trisodium 7-Hydroxy-8- ((4- (1- (4- (1-Hydroxy-4-Sulphonato-2-Naphthyl) Azo) Phenyl) Cyclohexyl) Phenyl) Azo) Naphthalene-1,3-Disulphonate?
To prepare Trisodium 7 - Hydroxy - 8 - {[4 - (1 - {4 - [ (1 - Hydroxy - 4 - sulphonato - 2 - naphthyl) azo] phenyl} cyclohexyl) phenyl] azo} naphthalene - 1,3 - disulphonate, the preparation method requires a multi-step reaction.
In the first step, when a specific amount of 1 - hydroxy - 4 - sulfonate - 2 - naphthylamine is taken, it is dissolved in an appropriate amount of dilute acid, cooled to a low temperature, about 0 - 5 ° C, and slowly added dropwise with sodium nitrite solution for diazotization. This step requires strict control of temperature and drip speed, so that 1-hydroxy-4-sulfonic-2-naphthalamine is fully converted into diazo salts to ensure the completeness of the reaction.
In the next step, take another 4- (1- (4-hydroxyphenyl) cyclohexyl) aniline, dissolve it in an appropriate basic solution, and then cool it to a low temperature. Then slowly add the diazo salt obtained above to carry out the coupling reaction. During the reaction, constant stirring is required to control the pH value in an appropriate range, so that the two can be effectively coupled to form an azo compound containing a specific structure.
Subsequently, the azo compound is further reacted with 7-hydroxy-naphthalene-1,3-disulfonic acid under alkaline conditions. The reaction temperature and time are adjusted to promote the condensation reaction between the two, and the complete structure of the target product is gradually constructed.
After the reaction is completed, the reaction mixture is treated. The organic phase is extracted with a suitable organic solvent. Then evaporation, crystallization and other means are used to precipitate the product. After multiple recrystallization, high-purity water or specific organic solvents are used to improve the purity of the product, and finally obtain Trisodium 7 - Hydroxy - 8 - {[4 - (1 - {4 - [ (1 - Hydroxy - 4 - sulphonato - 2 - naphthyl) azo] phenyl} cyclohexyl) phenyl] azo} naphthalene - 1,3 - disulphonate. Throughout the preparation process, the control of reaction conditions and material proportions in each step are crucial, which are related to the quality and yield of the product.
What is the market price of Trisodium 7-Hydroxy-8- ((4- (1- (4- (1-Hydroxy-4-Sulphonato-2-Naphthyl) Azo) Phenyl) Cyclohexyl) Phenyl) Azo) Naphthalene-1,3-Disulphonate?
Prices in Guanfu City are fickle and often fluctuate due to various reasons. As for this "Trisodium + 7 - Hydroxy - 8 - ((4 - (1 - (4 - (1 - Hydroxy - 4 - Sulphonato - 2 - Naphthyl) Azo) phenyl) Cyclohexyl) phenyl) Azo) Naphthalene - 1,3 - Disulphonate", its price is also difficult to determine.
The price of materials often depends on the abundance of raw materials, the simplicity of craftsmanship, and the situation of supply and demand. If the raw materials are abundant, easy to harvest, simple to make, and the market demand is small, the price is low; if the raw materials are rare, difficult to obtain, and troublesome to make, and there are many people seeking, the price will be high.
However, I have not personally involved in the trade of this product, so it is difficult to determine the price between the markets. Or you need to consult Jia people who specialize in this industry, visit the market of chemical materials, observe the records of their past transactions, and measure the changes in their supply and demand. Only then can you get a closer price. Even if you get it, it is only a temporary price. Tomorrow's market may be different, and it is difficult to measure.
