This substance is called tetrasodium 3,3 '- ({6- [ (2-hydroxyethyl) amino] -1,3,5-triazine-2,4-diyl} bis [imino (2-methylbenzene-4,1-diyl) ] (E) diazene-2,1-diyl) dinaphthalene-1,5-disulfonate, and its main application field is quite wide.
In the field of printing and dyeing, it can be used as a reactive dye auxiliary. In the matter of viewing printing and dyeing, if the dye is firmly attached to the fabric, the color is fresh and long-lasting, this auxiliary is indispensable. It can enhance the combination of the dye and the fabric, so that the dyeing is uniform and the color is full, as if the fabric is covered with gorgeous and long-lasting clothes.
In the paper industry, it is also very useful. When making paper, it is necessary to optimize the performance of paper, and this substance can be used as a paper reinforcer. It can strengthen the bonding force between paper fibers, improve the strength of paper, make paper tough and durable, and can cope with different use scenarios, just like giving paper a solid body.
In the paint industry, it may be a dispersant. The dispersion of pigments in paints is related to the quality of paints. This substance can make pigments evenly dispersed, prevent agglomeration, and ensure the uniformity and stability of paint color, just like building an orderly microstructure for paints.
In leather manufacturing, it may help leather dyeing and tanning. When dyeing, it helps the dye to penetrate, making the leather bright and bright; during tanning or participating in related reactions, it improves the performance of the leather, making the leather soft and durable, and seems to give the leather a unique quality and charm.
This substance plays a key role in many industrial fields by virtue of its own characteristics, just like an indispensable link in the industrial production chain, promoting the development of various industries.

This is a chemical product, named tetramethylamino 3,3 '- ({6- [ (2-ethyl) amino] -1,3,5-triazine-2,4-diyl} [amino (2-methylbenzene-4,1-diyl) ] (E) diazene-2,1-diyl) dinaphthalene-1,5-disulfonic acid. When using it, there is a lot to pay attention to.
First, this physical property should be inspected. It should be in the shape of a solid or liquid, so as to keep it well. If it is solid, prevent it from being damp; if it is a liquid, be careful of its leakage.
Second, it is safe to use. It may have a certain chemical activity, and the operation must be followed. It is advisable to prevent damage, such as gloves, eyes, and avoid contact between the skin and the eyes. If you accidentally contact the skin, quickly wash it with a lot of water, or in the case of severe damage.
Third, the use of the environment is also good. Keep it in a good place, avoid high altitudes and open flames, because the chemical materials are in an inappropriate environment, or cause reaction, causing danger.
Fourth, the dosage is fine. Take it in proportion according to the needs of the product or raw materials. Amount or insufficiency can cause deviation and affect the effectiveness.
Fifth, the reason is that the product should be used. Use the product, do not use it. According to the chemical management process, collect it separately and hand it over to the warehouse, so as to ensure safety and keep it away from pollution.

The method of preparing tetrasodium 3,3 '- ({6- [ (2-hydroxyethyl) amino] -1,3,5-triazine-2,4-diyl} bis [imino (2-methylbenzene-4,1-diyl) ] (E) diazene-2,1-diyl) dinaphthalene-1,5-disulfonate is quite complicated.
At the beginning, all kinds of raw materials need to be prepared. The key ones are naphthalene-based compounds with specific structures, triazines with specific amino groups, ethylamines containing hydroxyl groups, and sulfonation reagents. The raw materials must be pure, with a little impurity remaining, or the reaction may be perverse and the product is impure.
At the beginning of the reaction, naphthalene-based compounds are often used as the basis, and the sulfonation technique is first performed. When the temperature is too high, side reactions will multiply; if it is too low, the reaction will be slow, or it will be difficult to advance. The proportion of sulfonating agents also needs to be accurate, and more are over-sulfonated, and less are under-sulfonated, all of which are not as expected.
Then, the sulfonated naphthalene series is reacted with triazines. In this step, the catalytic agent is indispensable, which can promote the reaction speed and extract the yield of the product. The pH, temperature and time of the reaction system also need to be precisely controlled. Acid-base imbalance, or reaction arrest; temperature discomfort, or by-production; improper time, the purity and yield of the product are affected.
Subsequently, the (2-hydroxyethyl) amino group is introduced. During this process, the properties of the solvent and the slight changes in the reaction conditions are all related to success or failure. Solvent selection needs to take into account its solubility to the reactants and its impact on the reaction process.
Finally, after neutralization, separation, purification and other post-processing processes. During neutralization, the type and dosage of alkali are selected to determine the neutrality of the product; separation methods, such as filtration, extraction, etc., choose the appropriate one to remove impurities; purification uses recrystallization, chromatographic separation and other techniques to achieve high purity of the product.
Preparation of this compound requires careful attention in every step and good control of various reaction conditions to obtain the ideal product.
