"Tiangong Kaiwu" is a scientific and technological book written by Song Yingxing in the Ming Dynasty. It is written in classical Chinese, but you mentioned "Trisodium (3E) -5-Amino-6- { (E) - [4- ({4- [ (2E) -2- (2-Amino-4-Oxocyclohexa-2, 5-Dien-1-Ylidene) Hydrazinyl] Phenyl} Amino) -3-Sulfonatophenyl]} Diazenyl-4-Oxo-3- (2-Phenylhydrazinylidene) -3, 4-Dihydronaphthalene-2, 7-Disulfonate", which is a complex organic matter named by modern chemistry. When "Tiangong Kaiwu" was written, there was no such chemical understanding and naming, so it is difficult to answer according to its format.
But briefly describe the physical properties of this object in popular Chinese. This compound contains many functional groups. Looking at its structure, it may have a certain polarity. It contains sulfonic acid groups or is soluble in water and is in an ionic state. And because it contains aromatic ring structures, such as naphthalene rings, benzene rings, etc., there may be strong van der Waals forces between molecules, resulting in its melting point, boiling point or higher. It contains many chromogenic groups, such as azo, amino, carbonyl, etc., or has specific colors, or can be used in the field of dyes. However, this is only an inference based on the structure, and experimental measurements are needed to confirm its accurate physical properties.

The method of preparing (3E) -5-amino-6- { (E) - [4- ({4- [ (2E) -2- (2-amino-4-oxo-cyclohexyl-2,5-diene-1-subunit) hydrazino] phenyl} amino) -3-sulfophenyl] diazo} -4-oxo-3- (2-phenylhydrazinoxy) -3,4-dihydronaphthalene-2,7-disulfonate trisodium is quite complicated.
First, all kinds of raw materials need to be prepared, such as aryl amines containing specific substituents, naphthol derivatives and diazo salts related raw materials. In the ancient method, the suitable aromatic amine is first taken, and the amino group is activated after fine treatment, which is convenient for subsequent reaction.
Next, diazonium salts are prepared. The aniline compounds containing specific structures are carefully reacted with sodium nitrite under low temperature and strong acid environment to obtain diazonium salts. This process requires careful control of temperature and pH. If there is a slight difference, the diazonium salts are easy to decompose and cause the reaction to fail.
Then, the activated aromatic amine is coupled with the prepared diazonium salt. In a suitable buffer system, the pH value is precisely adjusted to allow the two to be coupled smoothly to form a key intermediate containing diazonium groups.
At the same time, the p-naphthol derivative should also be treated. Under specific conditions, the desired substituent is introduced at a specific position of naphthol, which lays the foundation for subsequent condensation reactions.
Finally, the intermediate containing diazo group and the treated naphthol derivative are condensed in an alkaline environment and at an appropriate temperature. After the reaction is completed, a series of post-processing steps, such as extraction, crystallization, purification, etc., remove impurities, and obtain (3E) -5-amino-6- { (E) - [4- ({4- [ (2E) -2- (2-amino-4-oxycyclohexyl-2,5-diene-1-subunit) hydrazinyl] phenyl} amino) -3-sulfophenyl] diazo} -4-oxo-3- (2-phenylhydrazinoxy) -3,4-dihydronaphthalene-2,7-disulfonic acid trisodium product. Strict procedures are required at every step to obtain satisfactory yield and purity.

"Tiangong Kaiwu" is a masterpiece of ancient Chinese science and technology. Although there is no such complex chemical in the book, according to common sense and chemical experience, it can be told as follows.
This "Trisodium (3E) -5-Amino-6- { (E) - [4- {4- [ (2E) -2 (2-Amino-4-Oxocyclohexa-2, 5-Dien-1-Ylidene) Hydrazinyl] Phenyl} Amino] -3-Sulfonatophenyl]} Diazenyl-4-Oxo-3- (2-Phenylhydrazinylidene) -3, 4-Dihydronaphthalene-2, 7-Disulfonate" is a fine chemical product with specific chemical activities and uses.
When used, the first priority is safety. Because of its complex structure, or unknown potential hazards. The operation must be well ventilated and equipped with protective equipment, such as gas masks, gloves, and goggles, to prevent it from contacting the skin and inhaling.
Furthermore, strictly control the amount. Weighing accurately according to the desired reaction or use, excessive or out-of-control reaction, not only waste of materials, or accidental side reactions, resulting in impurity products, affecting subsequent use.
In addition, pay attention to its stability. Complex structure or chemical properties are active, and are easily affected by temperature, humidity, and light. It is necessary to choose suitable storage conditions according to material properties, avoid high temperature, humidity, and strong light, and prevent deterioration and inactivation.
Repeat, know the compatibility taboos. Before mixing with other chemicals, check the reactivity in detail to avoid adverse reactions, such as violent reactions, precipitation, gas escape, etc., to avoid dangerous accidents and product quality problems.
At the end, properly dispose of it after use. The residue is disposed of in accordance with environmental protection and safety regulations and cannot be discarded at will to prevent environmental pollution and ecological harm. In this way, it is safe and effective to use and achieve the desired effect.
