Dimercaptopropanol is a good antidote, and its physical and chemical properties are unique, which is related to the healing effect and cannot be ignored.
Looking at its physical properties, dimercaptopropanol is a colorless to light yellow transparent liquid at room temperature, with a smell like garlic. Its boiling point is about 120 ° C - 122 ° C, and its relative density is between 1.238 and 1.242. It is slightly soluble in water, but it is highly soluble in organic solvents such as alcohols, ethers, benzene, and chloroform. This solubility makes it easy to interact with related substances in and out of the body.
As for chemical properties, dimercaptopropanol is rich in dimercapto groups in the molecule. This dimercapto group has high activity and can firmly bind to a variety of metal ions, such as arsenic, mercury, gold, bismuth, etc., to form stable complexes. This property is the core basis for its use as an antidote. When the human body unfortunately ingests poisons containing the above metal ions, dimercaptopropanol quickly binds to the metal ions to form non-toxic and easily excreted substances, thus achieving the purpose of detoxification.
Furthermore, dimercaptopropanol has strong reducing properties. Because the sulfur element in the thiol group is in a lower valence state, it is very easy to be oxidized. This reductive property can play an antioxidant role in the body, helping to reduce oxidative stress damage caused by poisons, protect the body's cells from free radical damage, and further consolidate its detoxification and protection of the body.
In short, the unique physical and chemical properties of dimercaptopropanol make it play a key role in the field of detoxification, making great contributions to saving the lives and health of poisoned patients.

Those who make acid are careful about several things in their production process.
The quality of the first raw materials. The purity and heterogeneity of the raw materials are directly related to the quality of the acid product. Purchase high-quality mineral sources, and check the amount of their components and impurities in detail before entering the factory. If there are many raw materials, the acid produced is impure, and it has a bad sound for all uses. If the raw materials with high iron content are used to make acid, the finished product may contain iron heterogeneity, which is unusable in fields such as electronics and medicine that require high purity.
The second time is the control of the reaction. The temperature, time, and proportion of the agent of the reaction are all key. To make acid, specific methods are often used, such as sulfuric acid and a certain mineral. If the temperature is low, it will slow down and the yield will drop; if the temperature is high, it may cause the side reaction and damage the quality of the product. The length of time is also important, and the reverse time is short, and the raw materials are not fully turned; over time, the energy consumption will increase, or there will be side effects. The proportion of the agent is unbalanced, and it is also unfavorable for the opposite to be complete and excellent in production.
Let's talk about the protection of the equipment again. Production depends on various equipment, such as reaction kettles, filters, etc. Whether the equipment is good or not, the efficiency and quality of the product are affected. Regularly check the equipment to check its abrasion, leakage, etc. If the wall of the reaction kettle is corroded, it will cause material leakage, the order of bad production, and there will be safety problems. The filter material is blocked, it is difficult to remove impurities,
Complex protection of the environment. During the acid making process, there may be waste gas, waste water, and waste residue. The waste gas contains harmful substances such as sulfur, which are discharged without passing through the place, polluting the air, damaging the ecology, and endangering the surrounding people and animals. Wastewater contains heavy gold ions, etc. If discharged directly, the sewage source will harm aquatic organisms. Waste residue should also be properly disposed of, otherwise it will occupy the soil and pollute the soil.
End and safety matters. Raw materials such as sulfuric acid have strong corrosion, and the operator is slightly sparse, and it will hurt if touched. During the reaction or pressure change, improper control, there is a risk of explosion. Therefore, it is necessary to establish safety regulations, operators must be familiar with safety, equipped with protective equipment, and equipped with safety control equipment to ensure the smooth production and the safety of personnel.

Guan Er's question is about the market price trend of cadmium diaminonaphthalenesulfonate. This is related to the rheology of business affairs, and it is difficult to say for sure.
The market is fickle, and the rise and fall of prices are influenced by various factors. First, the balance between supply and demand. If there are many people who want it, and there are few producers, the price will rise; on the contrary, if the supply exceeds the demand, the price will fall. If the times change, the industry will use more and more of this product, and the workshop will not produce enough, the price will jump.
Second, the change in cost. The price of raw materials, labor costs, and energy consumption are all costs. If raw materials are scarce, the price will be high, causing the cost of this product to rise, and the price will also rise. Another example is the increase in labor tariffs, or the sudden change in the price of energy consumption, which can change its cost, which in turn affects the price of the market.
Third, the regulations of the government. The laws and decrees issued by the government are related to the production, sales and circulation of this product, and can also affect its price. If strict regulations are established, the production is restricted, or taxes are increased, the price will rise; if the government is beneficial and the industry is helped, the price may stabilize, or even drop.
Fourth, the movement of the world situation. The situation in the world, or peace, or strife, all have an impact. Wars are disrupted, traffic is blocked, goods are difficult to pass, and prices will fluctuate. Economic prosperity and decline are also linked to prices. In prosperous times, the economy is prosperous, the demand is strong, and the price may rise; in declining times, the demand is weak, and the price may fall.
Therefore, if you want to know the market price trend of cadmium diaminonaphthalenesulfonate, you must look at the factors of supply and demand, cost, government orders, and the world situation, and analyze them in detail to get a rough estimate, but it is difficult to predict the change.

"Tiangong Kaiwu" says: "Where sulphur is combined with nitrate, then gunpowder becomes sound." However, this is a matter of gunpowder, and it seems to have nothing to do with the storage conditions of diaminonaphthalene and cadmium sun-acid. Today, the storage conditions of cadmium sun-acid are quite important.
Cadmium sun-acid has certain toxicity and chemical activity. When stored, the first environment is dry. If the environment is humid, water vapor is easy to chemically react with cadmium sun-acid, causing it to deteriorate, so it should be placed in a dry place, such as a storage cabinet equipped with desiccant.
The second is appropriate temperature. Excessive temperature can enhance the molecular activity of cadmium sun-acid, causing unstable changes; too low temperature or cause its physical state to change, affecting the quality. It should usually be stored in a place with small temperature fluctuations at room temperature to maintain its chemical stability.
In addition, it needs to be protected from light and shade. Light or luminescent chemical reactions cause damage to the structure and properties of cadmium tanning acid. It should be placed in a brown bottle or a dark container, and then placed in a dark place to protect it from light.
In addition, it should be kept away from fire sources, heat sources and strong oxidants. Cadmium tanning acid may react violently in the event of an open flame, hot topic or strong oxidant, which may cause danger. And it needs to be placed separately from other chemicals, especially with substances that can react with it, to prevent accidents.
In short, the storage of cadmium tanning acid can ensure its storage safety and quality stability only when the requirements of drying, temperature, light protection, fire protection and isolation are adhered to.
