Quinoline-5-carboxylic acid

Borax is one of the flavors of traditional Chinese medicine. Its main uses are various.
First, external use can clear away heat and detoxify. For diseases such as swelling and poison in sores, sore throat, sores on the mouth and tongue, borax is often chosen by doctors. Ancient physicians, in case of throat redness, swelling, heat and pain, often used borax in combination with other medicines to make a powder and blow it on the affected area. Cover because of its cold nature, can dissipate local heat toxicity, make redness and swelling gradually disappear, and the pain is relieved. The "Encyclopedia of Surgery Physicians" contains many prescriptions based on this method, which are used to treat all kinds of sores and diseases, and have good results.
Second, internal administration can clear the lungs and reduce phlegm. When there is phlegm heat in the lungs, and the cough phlegm is yellow and sticky, borax can exert its phlegm-reducing power. It can clear the fire in the lungs, make the phlegm hot, clear the lung qi, and reduce the symptoms of cough and expectoration. Ancient classics also have relevant discussions, saying that it has a conditioning effect on the phlegm heat in the lungs.
Third, in the fields of ancient alchemy and craft production, borax also has its uses. In alchemy, borax can be used as an auxiliary agent to participate in the refining process of medicinal pills, helping it to undergo specific chemical reactions to refine the required medicinal pills. In process production, such as ceramic firing, borax can be used as a flux to reduce the melting point of ceramic raw materials, make the firing process smoother, and improve the texture and color of ceramics, making them more exquisite.
Of course, although borax has many functions, it is cold and toxic. When taking it internally, be careful and follow the doctor's advice. Do not use it yourself to avoid damage to the body.

Borax, also known as sand and basin sand, is a very important mineral with unique physical properties.
The color of borax is usually white and colorless, with occasional light gray, light yellow, light blue and other light colors. Its crystals are often plate or columnar, and the aggregates are mostly granular, soil or dense blocks. Borax has a glassy luster, which makes the appearance of borax quite bright.
Looking at its hardness, the Mohs hardness of borax is about 2-2.5, which is relatively low. The texture is relatively soft, and fingernails can leave marks on its surface. Its cleavage is complete, and it is easy to break into a smooth surface in a specific direction.
The density of borax is about 1.69 - 1.72g/cm ³, which is relatively light. In terms of solubility, borax is easily soluble in water, and its aqueous solution is alkaline.
When heated, borax changes wonderfully. When heated to a certain extent, borax will lose its crystalline water and expand in volume, resembling boiling. If it continues to heat up, it will melt into a transparent glassy substance.
Borax is widely used in many fields. In the field of medicine, it has the effect of clearing away heat and detoxifying, reducing swelling and preventing corrosion; in industry, it is an indispensable raw material for the manufacture of glass, ceramics, enamels, etc.; in daily life, it is also common in some detergents and cosmetics. Its unique physical properties lay the foundation for its important position in various industries.

The chemical synthesis method of borax, although not available in detail in ancient times, is still available in ancient books.
In the past, chemical synthesis relied on the accumulation of experience and repeated attempts. To obtain borax, the first choice of raw materials. Borax is also made from boron-containing compounds. In ancient Fangjia, boron-containing ores, such as borosite, were often found. This is the basis for synthesis.
Borosite and other ores are soaked in water, filtered through again, to remove the residue and leave the liquid. Later, add alkali to the clear liquid to adjust its pH. For alkali, such as potassium carbonate dissolved in plant ash, this is a key step. Due to the different shapes and reactions of boron compounds under different pH levels. After moderate alkalization, boron can be retained in the solution in a suitable form.
Then, heat the solution. Control of the heat is of paramount importance. Slow down the heat and boil slowly, so that the water is gradually lost and the solution is gradually thickened. When it has signs of crystallization, move it to a cool place to allow it to crystallize naturally. At this time, the crystals of borax are gradually formed.
Then the borax obtained by this method may contain impurities. The ancients also had a method of purification. The borax that is recrystallized in hot water is filtered to remove its insoluble matter. After cooling and crystallizing, a purer borax can be obtained.
Furthermore, there are those who react borax with other substances to make special borax compounds. If borax is reacted with acid, boric acid-related products can be obtained. In this process, the products vary according to the type and amount of acid used.
Although the ancient method is viewed in the present, or there are simple aspects, its exploration spirit and practical experience lay the foundation for the development of chemical synthesis in later generations. Although today's chemical synthesis of borax is more accurate and efficient, it can be traced back to its origin and inherits the wisdom of the past, constantly evolving and improving.

Fossil-5-boric acid is used in various fields, as follows:
First, the field of medicine. Boric acid has the ability to disinfect and prevent corrosion. In the past, doctors often used its dilute solution as a rinse agent for eyes, mouth and skin wounds, which can prevent infection and promote healing. If the eyes are red, swollen and painful, wash the eyes with boric acid solution, which can clear the eyes and reduce swelling. It is also used as a raw material in pharmaceuticals. Some external ointments and medicines often contain boric acid, which can treat skin diseases with its properties.
Second, the chemical industry. Boric acid is an important raw material for the preparation of borides and borates. These compounds are widely used in the manufacture of glass, ceramics and enamels. In glass production, adding boric acid can reduce the melting point of glass, increase its thermal stability and chemical stability, and make the glass tougher and more heat-resistant. For example, in the production of heat-resistant glassware, boric acid is indispensable. In ceramic and enamel processes, boric acid can help color glazes adhere evenly, increase their luster and hardness, and make ceramics and enamel products more beautiful and durable.
Third, agricultural category. Boric acid is a trace element required for plant growth. Appropriate application of boric acid to soil can promote the development of plant reproductive organs, increase fruit setting rate and seed setting rate. Especially in rape, cotton and other crops, boron deficiency will cause flowers to fail, so boric acid is effective in agricultural production.
Fourth, electronic industry. Boric acid is also useful in the manufacture of semiconductor materials and electronic components. It can participate in the preparation of electronic-grade chemicals, ensure the stability of electronic components, and contribute significantly to improving the quality and reliability of electronic products.

The market prospect of boric acid is related to many factors, and today is the analysis of you.
From the perspective of its use, boric acid has a wide range of uses. In the glass industry, it can be used as a flux to increase the transparency and heat resistance of glass, making glassware beautiful and strong. It is suitable for the manufacture of optical glass, heat-resistant glass, etc. Today's technology is advancing, and the demand for high-quality glass in the fields of electronics and optics is constantly increasing, so is the need for boric acid. For example, glass plates with electronic display have strict performance requirements, and the effect of boric acid is indispensable, which opens up a broad market space for boric acid.
In the field of medicine, boric acid has the ability to disinfect and prevent corrosion. In the past, it was often used to make disinfectants for wound cleaning and skin disease healing. Although new agents are emerging today, boric acid still plays a role in some pharmaceutical scenes due to its mild nature and moderate cost. With the expansion of the pharmaceutical industry, its demand may also rise steadily.
On the chemical industry again, boric acid is an important chemical raw material. Boron compounds can be produced, which are used in the production of flame retardants and catalysts. The stronger the awareness of fire prevention in today's society, the wider the market for flame retardants, and boric acid is its key raw material, which has promising prospects. Catalysts are crucial in chemical production. Catalysts made of boric acid can promote efficient reactions and contribute greatly to the development of chemical industry.
However, its market also has challenges. Other alternatives may be available. If a substitute with excellent performance and low cost is developed, the boric acid market may be impacted. And environmental protection regulations are becoming stricter. If the boric acid production process does not meet environmental protection standards, enterprises will need to spend huge sums of money to rectify, increase production costs, and compete or be disadvantaged in the market.
To sum up, boric acid is widely used in glass, medicine, chemical industry and other fields, and the market prospect is good. However, it is necessary to face the threat of substitution and environmental protection pressure head-on. Enterprises should focus on research and development, improve production efficiency, reduce costs, and respond to environmental protection in order to stabilize in the market tide and ensure its development.
