"'Disodium 8- (Phenylamino) -5- [ (E) - {4- [ (E) -Phenyldiazenyl] -7-Sulfonatonaphthalen-1-Yl} Diazenyl] Naphthalene-1-Sulfonate' The production process is as follows:
First of all, the raw materials need to be prepared, such as compounds containing naphthalene and benzene, and the purity and quality need to be paid attention to, which is the foundation of production. The relevant raw materials are placed in a special reactor according to the exact ratio. This ratio needs to be determined by long-term practice and accurate calculation. The slightest difference may affect the quality of the product.
Then, the reaction temperature and pressure are controlled. At the beginning of the reaction, the temperature in the kettle is slowly raised to a suitable range by a gentle heating method, and the pressure is stabilized at a specific value, so as to create an environment conducive to the reaction. This process is like riding a horse and driving a car, and it needs to be smooth and accurate.
When reacting, add a specific catalyst to promote the reaction rate and efficiency. The choice of catalyst is crucial, and it needs to fit this specific reaction mechanism in order to maximize its effectiveness. And when adding, you need to pay attention to the timing and dosage. If you are not careful, it is easy to cause the reaction to go out of control.
During the reaction process, closely monitor the degree of reaction, and use precision instruments and experienced craftsmen to observe. According to the change of reaction, fine-tune the temperature, pressure and other conditions in a timely manner to ensure that the reaction advances along the expected path.
When the reaction reaches the expected level, separate and purify the product. Use filtration, extraction, crystallization and other methods to remove impurities and improve the purity of the product. This process requires careful operation to avoid product loss or the introduction of new impurities.
Finally, the purified product is strictly tested and its indicators are checked according to relevant standards. Only if the indicators meet the standards can the qualified product be packaged and put into storage for use.
This production process is interlocking, and it needs strict operation and fine control to obtain high-quality'Disodium 8- (Phenylamino) -5- [ (E) - {4- [ (E) -Phenyldiazenyl] -7-Sulfonatonaphthalen-1-Yl} Diazenyl] Naphthalene-1-Sulfonate 'products.

"Disodium 8- (phenylamino) -5- [ (E) - {4 - [ (E) -phenylazo] -7 -sodium sulfonate naphthalene-1-yl} azo] naphthalene-1 -sulfonate" Compared with other congeneric products, its advantages are as follows:
In terms of dyeing process, this product has the unique beauty of uniform and firm coloring. Looking at the same kind, there are many uneven coloring, resulting in mottled color of the finished product and affecting the appearance. However, with its delicate molecular structure, this product can be evenly distributed among the fabric fibers. When coloring, the color is uniform and there is no difference in depth. And it is firmly combined with the fiber. After many washes and rubbing, the color is not easy to fade, and it will keep its freshness for a long time.
Furthermore, this product has a wide range of applications. Congeneric products are often limited to specific fabrics, such as those suitable for cotton, but poor linen. Whether it is natural fibers such as cotton, linen, silk, wool, or man-made fibers such as polyester and nylon, this product can show excellent dyeing performance, providing more choices for dyeing craftsmen to meet the needs of various fabrics.
In addition, its environmental protection is also a highlight. At present, environmental protection is the most important, and many congeneric products are prone to harmful substances and pollution of the environment during production or use. The production process of this product is excellent, and the damage is strictly controlled. The chemicals contained in it comply with environmental protection regulations. It is harmless to the ecology. It not only conforms to the current situation, but also protects the beauty of nature.

"8- (phenylamino) -5- [ (E) - {4- [ (E) -phenylazo] -7-sulfonated naphthalene-1-yl} azo] naphthalene-1-sulfonate disodium" This product, because the specific product characteristics, market supply and demand, quality grade and other key factors are not clear, it is difficult to determine its market price range.
From the perspective of "Tiangong Kaiwu", in the past, when it came to the price of various materials, it was often necessary to consider the origin, texture, season and other reasons. If the product is a pigment or the like, the difficulty of its raw material source and the simplicity of its production process will affect its price. If the raw materials are scarce and the production requires exquisite techniques, the price will be high; on the contrary, if the raw materials are common and the process is simple, the price may be slightly lower.
And the state of market supply and demand is also the main reason. If the demand for this product in the market is strong, but the supply is limited, the price will rise; if the supply exceeds the demand, the price may fall. And the economic conditions and trade circulation of various regions also affect the price. In prosperous places, the price may be high; in remote places, the price may be relatively low. However, without knowing many details of this product, it is difficult to accurately determine its market price range.
