Sodium-1- (1-naphthyl azo) naphthalene-2-alcohol-3,6-disulfonate needs to pay attention to many key matters in the production process.
First, it is related to the properties of the material. This compound is an organometallic salt with specific chemical activity and stability. At the beginning of production, it is necessary to know its physical and chemical properties, such as solubility, melting point, stability, etc. Because solubility is related to the choice of reaction solvent. If the solvent is improper or the reaction is uneven, the yield will be reduced. If the stability is poor, the storage and reaction conditions need to be carefully controlled to prevent decomposition and deterioration.
Second, the reaction conditions are extremely critical. In terms of temperature, it must be precisely controlled. If the temperature is too high, or the side reaction is triggered, the purity of the product will be reduced; if the temperature is too low, the reaction rate will slow down, the time-consuming will increase, and the production efficiency will be affected. Take the common synthetic reaction as an example, the reaction temperature may need to be maintained in a narrow range, and the deviation should not be too large. Furthermore, the pH of the reaction system cannot be ignored. This compound is more sensitive to acid and alkali, and the peracid or peralkali environment can affect the reaction process and product structure.
Third, safety protection should not be underestimated. During production, or contact with this compound and its related raw materials, some may be toxic and irritating. Therefore, operators should strictly wear protective equipment, such as protective clothing, gloves, goggles, etc., to prevent skin contact and inhalation. The workshop also needs to be well ventilated to discharge harmful gases in time.
Fourth, quality control is of paramount importance. From raw material input to product output, all links need to be strictly monitored. If the purity of raw materials does not meet the requirements, it will directly affect the product quality. Sampling and testing should be conducted regularly during production, and appropriate analytical methods, such as high performance liquid chromatography, mass spectrometry, etc. should be used to ensure that the product purity and structure meet the standards.

Sodium 1- (1-Naphthylazo) Naphth-2-Ol-3,6-Disulphonate, the Chinese name is often naphthalene azo naphthol disulfonate sodium, this material is used in dyeing and weaving and other industries. Although there was no such thing in the era involved in "Tiangong Kaiwu", it is related to hidden dangers based on the cognition of dyes and other substances in ancient times.
If this chemical is accidentally scattered and exposed, the chemical groups it contains may interact with water vapor and oxygen in the air. According to the ancient concept, qi is the source of all things, and the gas of this foreign body is mixed into the air or inhaled by people. If people inhale it, it may hurt the lungs and cause coughing, asthma and other diseases. In ancient times, there was "evil, its qi will be weak", and the human body's righteous qi will be damaged, and it is prone to diseases.
If this thing flows into the water, the water is the source of life, and all things flow in it. According to ancient understanding, water is polluted, drinking this water may make the human body's qi and blood impaired. Aquatic organisms bear the brunt, or cause death of fish and shrimp, etc., destroying the ecological balance of the water. Ancient cloud "aquatic things", the ecological damage of the water, affecting water-based industries, such as fishing.
On land, if it penetrates into the soil, it will affect the soil fertility and properties. In ancient farming, whether the soil is fertile or not depends on the harvest. Soil is polluted, and the growth of crops is affected, resulting in lower yield, lower quality, and endangering people's livelihood.
In short, although there was no such chemical in the era of "Tiangong Kaiwu", according to the ancient understanding of the relationship between all things in nature, its exposure to sprinkling will have adverse effects on air, water, soil, etc., threatening human health, ecological balance and people's livelihood.
