Lead, one of the hardware, is soft and heavy, with many physical properties.
Lead is gray in color and has a restrained luster. It is not as dazzling as gold and silver, but it also has a simple state. Its texture is soft, can be scratched by nails, and it has good ductility. It can be beaten into thin sheets or pulled into thin threads, which is convenient for craftsmen to shape according to their needs.
Lead has a high density and is heavier than ordinary metals. If you hold it, you can feel its heaviness. This property makes lead very useful in many places that need to be weighted, such as placing lead on the bottom of a ship when building a ship to stabilize the hull and resist the invasion of wind and waves.
Furthermore, the melting point of lead is relatively low, about 300 degrees. After a little calcination in the fire, it melts into a liquid and is easy to cast. And lead has good corrosion resistance, is not easy to be oxidized in the air, and can maintain its own form and properties for a long time. It is often made into containers to hold special liquids, or used for building waterproofing, underground pipeline protection, etc.

What are the chemical properties of 4-hydroxy-3-pyridine sulfonic acid?

Alum has unique chemical properties and many wonders.
First, alum is acidic. In water, alum can dissociate hydrogen ions, causing its aqueous solution to be acidic. This acidic property often plays an important role in many chemical reactions. If some metals meet an aqueous solution of alum, it is like a warrior meeting an enemy and a replacement reaction occurs. Take iron as an example. When iron is put into the alum liquid, it is like a battlefield confrontation. Iron atoms lose electrons and dissolve into ferrous ions into the solution, while metal ions in alum gain electrons and precipitate into elemental matter. This process is like a microscopic world battle, showing the wonders of chemistry.
Second, alum is oxidizing. Under certain conditions, some high-valence metal ions in alum are like dominators with strong power, capable of seizing electrons from other substances and reducing their own valence. This oxidizing property is widely used in chemical production and other fields, such as for oxidizing certain organic compounds to help generate the desired products, just like craftsmen skillfully carve and shape various delicate items.
Third, alum is hydrolytic. When alum dissolves in water, it is like throwing it into a stone on the surface of a calm lake, triggering a series of changes. Its metal cations combine with hydroxide ions ionized by water to produce a hydrolysis reaction, which increases the concentration of hydrogen ions in the solution and further enhances the acidity of the solution. This hydrolysis process also has an impact on the environment and other aspects. For example, in water treatment, the colloidal substances produced by the hydrolysis of aluminium are like magical adsorbents, which can absorb suspended impurities in water, purify the water, and provide people with clean water.
Fourth, alum can form complexes. Under suitable conditions, metal ions in alum are like hospitable people, and can combine with specific ligands to form complexes with unique structures. These complexes are of great value in chemical research and industrial applications. For example, in the field of catalysis, some complexes formed by alum can be used as efficient catalysts to accelerate the reaction process and improve production efficiency. It is like giving wings to chemical reactions and making them move forward rapidly. Alum has diverse chemical properties and plays an indispensable role in many fields, providing many benefits to human life and production.

What is the synthesis method of 4-hydroxy-3-pyridine sulfonic acid?

To make 4-cyano-3-nitrobenzoic acid, the following ancient method can be used.
Take the appropriate raw material first, and use benzoic acid as the starting material. Put the benzoic acid in the reactor, add an appropriate amount of fuming nitric acid and concentrated sulfuric acid mixed acid system. In this mixed acid system, nitric acid can provide nitro groups, and sulfuric acid is the catalyst and dehydrating agent for the reaction. Under the condition of low temperature and stirring, slowly add the mixed acid dropwise to make the benzoic acid nitrate, and 3-nitrobenzoic acid can be obtained. In this process, the control of low temperature is extremely important to prevent the reaction from being too violent and causing side reactions.
After 3-nitrobenzoic acid is prepared, impurities are removed through separation and purification steps to ensure the purity of the product. Thereafter, 3-nitrobenzoic acid is reacted with potassium cyanide or other suitable cyanide reagents in a suitable solvent. This reaction needs to be carried out in an alkaline environment, and an appropriate amount of alkali can be added, such as sodium carbonate. During the reaction, the cyano group will replace the appropriate group on the benzoic acid to generate 4-cyano-3-nitrobenzoic acid.
After the reaction is completed, it is further purified by a series of post-treatments, such as filtration, washing, recrystallization, etc., to obtain pure 4-cyano-3-nitrobenzoic acid.
However, it should be noted that cyanide reagents are highly toxic. When operating, it is necessary to strictly follow safety procedures, work in a well-ventilated environment, and take protective measures to prevent the risk of poisoning. The conditions of each step in the reaction process, such as temperature, reagent dosage, reaction time, etc., need to be precisely controlled to achieve satisfactory yield and purity.

What is the price range of 4-hydroxy-3-pyridine sulfonic acid in the market?

Those who ask today, ask about the price of alum in the market. Alum is used in a wide range in the market, and its price varies from time to time, and also varies with the quality and the distance of the land.
Looking at the cities, the price of the best alum may be between ten and twenty gold. The quality of this alum is pure and good, and it is used in dyeing houses, medicine shops, etc., because of its quality, so the price is not cheap.
Medium alum, the price is about hardware to ten gold. Its quality is acceptable, although it is not as pure as the best, it is enough for ordinary work, so the price is slightly inferior.
As for the lower alum, the price is between three gold and hardware. The price is the cheapest.
The distance of the place is also related to the price of alum. For those who are near the place of origin, the price may be slightly lower because there is no long-distance transportation fee; and for remote areas, if the freight is added, the price will increase. And the time is different, the supply and demand are different. If there is a boom in alum, there are many applicants and few suppliers, the price will also increase; if it is off-season, the supply exceeds the demand, and the price will drop from time to time.
All of these are the approximate range of the alum price in the market. However, the market conditions are ever-changing, and they cannot be rigid. You must check it at any time to know the exact price.
