To prepare Tetrasodium 3,3 '- (Carbonylbis (Imino (5 - Methoxy - 2 - Methyl - 4,1 - Phenylene) Azo)) Bis (Naphthalene - 1,5 - Disulphonate), the method is as follows:
Prepared raw materials, 5 - methoxy - 2 - methyl - 4,1 - phenylenediamine, 1,5 - naphthalene disulfonic acid and other kinds. 5 - methoxy - 2 - methyl - 4,1 - phenylenediamine needs to be finely purified to ensure that impurities do not disturb subsequent reactions. 1,5 - naphthalene disulfonic acid must also meet the corresponding purity standards.
The first step is the coupling reaction. In a suitable reactor, the treated 5-methoxy-2-methyl-4,1-phenylenediamine is added with a specific organic solvent as the medium, and stirred to disperse uniformly. Then slowly add the solution containing carbonyl diimidazole dropwise to control the dropwise rate and reaction temperature. This process needs to be carefully monitored, because the temperature and dropwise rate have a great influence on the reaction process and the purity of the product. Wait for the reaction to be smooth and keep warm for a period of time, so that the coupling reaction can be fully carried out.
Next step, transfer the product of the first step into another reaction device and add 1,5-naphthalene disulfonic acid. In this step, the pH of the reaction system needs to be adjusted and regulated by specific alkaline substances. During the reaction, moderate heating and stirring are applied to promote the full reaction. During this period, the reaction process can be closely monitored, and the degree of reaction and product formation can be detected by means of chromatographic analysis.
After the reaction is completed, separate and purify. First, the insoluble impurities in the system are removed by filtration. The filtrate is extracted with an organic solvent and extracted several times to fully enrich the target product. After that, the organic solvent is removed by vacuum distillation. Then the product is further purified by recrystallization. Choose a suitable solvent to dissolve the product, slowly cool down, and crystallize the product. Repeat the recrystallization operation several times to obtain high purity Tetrasodium 3,3 '- (Carbonylbis (Imino (5 - Methoxy - 2 - Methyl - 4,1 - Phenylene) Azo) Bis (Naphthalene - 1,5 - Disulphonate).
The whole preparation process requires strict compliance with the operating procedures and attention to the details of each link to ensure the quality and yield of the product.

Wen Zi asked about the potential safety risks of Tetrasodium 3,3 '- (Carbonylbis (Imino (5 - Methoxy - 2 - Methyl - 4,1 - Phenylene) Azo) Bis (Naphthalene - 1,5 - Disulphonate). This is a chemical substance with a complex structure.
In the context of "Tiangong Kaiwu", although there is no such precise modern chemical, it can be compared. In ancient times, when the nature of the substance was unknown, it was often treated with caution. Although this chemical has a complex name, its composition is composed of organic structures and sulfonates. The organic part may involve reactivity, and sulfonates affect solubility and ionic properties.
If in ancient times, consider its latent risk, or first look at its appearance characteristics, such as color, taste, and state. If this substance has a pungent taste or abnormal color, it may be harmful. In addition, observe its changes in different media, such as water, oil, etc. If it reacts violently, it will also warn of risks. Although there is no modern accurate instrument to determine toxicity, flammability, etc., based on ancient experience, from its reaction with common substances, as well as its impact on the surrounding environment and organisms, one or two can be inferred.
And ancient craftsmen, in contact with new objects, often test a small amount, and gradually explore. If this chemical is tested in a very small amount by the ancient method or in an open and ventilated place before, see if it has any abnormal effects on the air and soil. If there are organisms that are disturbed near, such as insects and birds, it also indicates hidden risks. In summary, even with the ancient method, some hidden safety risks can be detected to ensure the safety of the person.
