quinoline-4-carboxylate

Borax is the common name of sodium tetraborate, and its chemical structure is quite unique. The chemical formula of borax is $Na_2 [B_4O_5 (OH) _4] · 8H_2O $. From its structure, it contains $[B_4O_5 (OH) _4] ^ {2 -} $anions and $Na ^ + $cations, as well as crystalline water molecules.
In the $[B_4O_5 (OH) _4] ^ {2 -} $anion, the four boron atoms present two different coordination environments. Two of the boron atoms exist in the form of a $BO_3 $plane triangle, while the other two exist in the form of a $BO_4 $tetrahedron. The two structural units are connected to each other by oxygen atoms, forming a unique ring structure. In the $BO_3 $planar triangular structure, the boron atom is in the center of the plane and is connected to the three oxygen atoms by covalent bonds. The boron-oxygen bond length is short and the bond angle is close to 120 dollars ^ {\ circ} $, showing a planar triangular configuration. In the $BO_4 $tetrahedral structure, the boron atom is located in the center of the tetrahedron and is covalently bonded to the four oxygen atoms. The boron-oxygen bond length is slightly longer than the boron-oxygen bond in the $BO_3 $, and the bond angle is also different. The $Na ^ + $cation binds to the $[B_4O_5 (OH) _4] ^ {2 -} $anion through electrostatic action, maintaining the electrical neutrality of the whole compound. At the same time, crystalline water molecules interact with anions and cations in a certain way and exist in the lattice, which has many effects on the physical and chemical properties of borax, such as affecting its solubility and stability. Borax's unique chemical structure makes it show unique properties and uses in many fields, such as chemical, pharmaceutical, metallurgical and other industries.

Borax is a kind of traditional Chinese medicine, which is mainly used in a variety of ways. In the way of medicinal use, borax has the effect of clearing away heat and detoxifying, and is often used to treat sore throat, sores on the mouth and tongue, and blindness. If the throat is swollen and sore, it can be used with borneol, Xuanming powder, cinnabar, etc. to blow on the throat at the end of the study to reduce swelling and relieve pain; when the mouth is sore, borax can also be used in combination with heat-clearing and detoxifying products to clear away heat and purge fire, reduce sores and build muscles.
In the field of industry, borax is widely used. In the glass industry, it can be used as a flux and clarifying agent to make the glass more uniform and transparent, and to improve the heat resistance and chemical stability of the glass. It is often used in the manufacture of advanced optical glass, heat-resistant In the enamel industry, borax can enhance the luster and firmness of enamel products. As an important component of glaze, it makes the enamel surface smoother and more durable.
In the chemical industry, borax is a key raw material for the preparation of boron compounds. Many boron-containing chemicals are made of borax as the starting material. In the metallurgical industry, borax can be used as a flux for metal welding to remove oxides on metal surfaces, making welding more firm and ensuring welding quality.
In daily life, borax is also used. In the past, it was occasionally used in some food processing, but now it has been strictly restricted due to its toxicity. However, in some special process foods, such as some traditional pasta production, it has been used in small amounts to improve the taste and quality. In addition, in detergents, borax can be used as an additive to enhance decontamination ability and softening effect.
In short, borax has various uses, but because of its toxicity, it needs to be used in accordance with norms and safety standards to prevent harm to human health and the environment.

The method of making borax has been known in ancient times. In the past, the Fang family often started with natural boron ore, and after many quenches, the essence of borax was obtained. The method is as follows:
First find high-quality boron ore, choose its pure and strong color, and crush it into small pieces. Put it in the pottery kettle, add an appropriate amount of alkali, and add water to impregnate it to ensure that the ore blocks are moist. Then, cook it slowly over a slow fire, during which it needs to be stirred frequently to make the ore and alkali blend evenly. The fire should not be too intense to prevent it from boiling and overflowing, and to avoid mineral damage.
Wait for the liquid in the kettle to gradually thicken, the color is slightly yellow, and let it stand. When it cools, it can be seen that the crystals are precipitated at the bottom of the kettle, which is coarse bor However, it still contains impurities and needs to be purified again.
The coarse borax is dissolved in hot water and filtered with a fine silk cloth to remove its dross. The filtrate is contained in the purifier, and it is slowly steamed over a low fire. The moisture is gradually lost, and the borax crystals reappear. The crystals at this time are more pure than before.
Repeat the steps of dissolving, filtering and steaming several times to obtain borax with extremely high purity. Although the ancient people made borax with simple tools, with experience and patience, they could also obtain this excellent product for medicine, alchemy, etc.
Later generations have advanced in technology, and have improved in raw material selection, reaction conditions control, and purification methods. However, the foundation of the ancient method cannot be forgotten. It lays the foundation for the preparation of borax in later generations and is the first of its kind in chemical technology.

Borax has different effects in different fields.
In the field of medicine, borax has the ability to clear away heat and detoxify. Gu Yun: "Borax has a sweet, salty, and cool taste. It can treat swollen throat and sore mouth and tongue." Because it can clear heat and reduce fire, it can relieve heat and poison. In case of laryngeal paralysis, borax is combined with various medicines, and the throat is blown at the end of the study to reduce swelling and pain, so as to restore the smoothness of the throat.
In the art of alchemy, borax is also useful. Alchemists know very well that borax can help the fusion of medicines, making the refining of medicinal pills more smooth. In the furnace fire, it can transform the strength of all stones, so that it can be fused seamlessly, so as to become a wonderful product of alchemy. Looking at the ancient alchemy scriptures, there are many records of the wonderful use of borax in alchemy, which can help alchemists achieve the purpose of gold and stone transformation.
As for industrial use, although it is not often involved in ancient times, it can also be inferred. Borax has the property of melting, if it is used in metallurgy, it can be like the fusion of stones in alchemy, which makes the melting of metals more convenient, reduces its melting point, makes impurities easy to separate, and improves the purity and quality of metals.
To sum up, borax plays an important role in different fields such as medicine and alchemy due to its unique characteristics, either relieving human suffering or assisting in the practice of alchemy.

In the field of boric acid, the market prospect can be improved. Since then, there has been a strong demand from all parties. Because of its use, it has an indispensable position in all industries.
Since then, boric acid has the good effect of disinfection and anti-corrosion. It is commonly used by manufacturers to improve the health of the people. In the field of chemical quality, it can balance the acid, protect the muscles, and make the capacity. Among ceramics, the addition of boric acid can improve the performance of the billet, make the color of the utensils and the ground. Glass manufacturing also helps to reduce the melting and increase the resistance and transparency of the glass.
In today's world, technology is changing with each passing day, and the demand for boric acid will continue to rise. Work is done well, new types of chemical products are not produced, ceramics and glass are also built in cities, and life is improved and flourished. This is all based on boric acid, which creates a new market.
However, the market prospect is beautiful, and there are also many challenges. Such as raw materials, or cost control; with the addition of new products, it is possible to obtain refined products and new jobs. However, in terms of boric acid, its multiple uses do not meet the needs of expansion, and the market prospect remains clear. If it is properly developed, it will definitely be able to find a place in the market and welcome the harvest.
