2-Quinoline boronic acid

Borax has a wide range of main uses, which are related to various matters, and are involved in medical practice and craftsmanship.
In the medical tract, borax is quite effective. It has a cool nature and has the ability to clear away heat and detoxify. It is often used by doctors to treat sores on the mouth and sore throat. There are many records in ancient medical books. Borax is used with various medicines, powders or pastes, and applied to the affected area, which can relieve the heat toxicity and gradually eliminate the swelling and pain. In case of pediatric thrush, use an appropriate amount of borax, grind it very finely, and blow it on the affected area to get good effect. Because it can clear away heat and reduce fire, and the texture is mild, it does not hurt the righteousness, so it is a commonly used medicine for oral and throat diseases.
As for the process, borax is also indispensable. In metallurgy, borax can be used as a flux. In ancient castings, it was difficult to melt the metal and remove impurities. When borax is put into the furnace, it can reduce the melting point of the metal, make the metal more easily fused, and remove impurities from it, making the casting texture more pure. Looking at ancient exquisite bronze and iron ware, borax is indispensable. In ceramic firing, borax can improve the properties of ceramics. It can make the ceramic body and the glaze more tightly combined, and can reduce the melting point of the glaze, making the glaze surface smoother and more uniform, and the color is radiant. The fired ceramics, whether plain and elegant or gorgeous, rely on the help of borax.
In addition, in the art of alchemy, borax is also occasionally used. Although borax is not the main medicine for alchemists to refine the medicine of longevity, it can also adjust the temperature and assist in the combination of various medicines in some pill formulas, in order to achieve the formation of medicinal pills. Although its alchemy is mostly absurd, the role of borax in it can also be seen in its wide range of uses.
In short, the use of borax, whether it is used to heal people's diseases or to improve craftsmanship, has its unique value in many aspects of the lives of the ancients, and is an indispensable material.

In "Tiangong Kaiwu", there are many ways to make calcite (calcite is calcite, ancient calcite or calcite used to be called), and there are two common ones.
One is the method of smelting. The natural calcite ore is mined, the quality is selected, and it is placed in the kiln. The kiln is built in a well-ventilated place, and firewood and charcoal are used as fuel. First lay thick charcoal at the bottom of the kiln, place ore on it, and then cover it with charcoal, and stagger layer by layer. When the fire is ignited and burned, the fire needs to be vigorous and even. When the firewood and charcoal are burned, the temperature of the kiln gradually rises. After several days of calcination, the ore is decomposed by heat, and the internal structure becomes easy. When it is burned to the right heat, stop and cool. After cooling, take out the burned thing, or qu The crushed stone is the crude product of calcite, which can be used for many purposes, such as medicine, glazing, etc.
The second is the method of weathering by water leaching. Find calcite veins in the mountains and mine large pieces of ore. Place the ore on the riverbank or wetland, so that it is often immersed in water or showered by rain. Over time, the ore is eroded by water, blown by the wind and the sun, and naturally weathered. The infiltration of water can dissolve impurities in the ore, and the wind blowing and sun exposure can gradually peel and decompose the surface layer of the ore. After years or even decades, the ore gradually becomes small or powdery. The calcite obtained is pure in texture and mild in nature, and is widely used in fine fields such as medicine and pigment preparation. Although this method of water leaching weathering takes a long time, the quality of the calcite produced is good, which is valued by the ancients.

Borax is a unique mineral with various physical properties. Its color is often white, light gray, light yellow or light blue, and the pure one is colorless. Its luster is as bright as glass, transparent to translucent, just like the quality of jade glass, and it is quite beautiful.
Its hardness is not high, about 2-2.5 degrees. With a little force on the nail, it can leave marks on it, like the quality of tender stone, and it feels soft to the touch. The specific gravity is also lighter, about 1.69-1.72. It feels light in the hand, not as heavy as gold and stone.
Borax is brittle and easily broken by force. When broken, its section often shows a shell-like or stagnant shape, like an ice crack. And it has good water solubility and gradually dissolves in water, which makes it useful in many fields.
Borax crystals are mostly plate-shaped or columnar, with regular crystal shapes and orderly arrangements, just like natural wonders. Its aggregates are diverse in shape, either granular, with compact grains, like sand gathered in piles; or soil-like, with fine texture and loose like fine soil.
Under light, borax often shows unique optical properties. Light penetrates, refracts, and reflects, and the color changes, which is wonderful. This kind of physical properties makes borax useful in various fields such as industry, medicine, and scientific research, giving full play to its unique function and adding a different color to many affairs in the world.

For borax, many matters should be paid attention to during storage and transportation.
First of all, for storage, borax is relatively stable, but it also needs to be placed in a dry, cool and ventilated place. If it is in a humid place, borax is easy to absorb moisture and deliquescence, causing its properties to mutate, affecting its quality and use. For example, if it is placed in a dark and humid place, borax may agglomerate for a long time, losing its original loose form. When used, it is difficult to disperse evenly, which is greatly unfavorable for subsequent applications.
Furthermore, it is appropriate to store it away from fire and heat sources. Although borax is not flammable, it may undergo chemical reactions under high temperatures, which will damage its chemical properties. And high temperature may also cause the crystal water contained in borax to dissipate, change its chemical composition, and reduce its efficacy.
As for transportation, when handling, be sure to handle it with care and never handle it rudely. Borax texture or brittle, if subject to severe vibration and collision, it is easy to break into powder, not only may cause package damage and leakage, but powdered borax is more likely to fly, pollute the environment, and may also be harmful to the health of transporters.
And the means of transportation should be clean, dry and well sealed. If the means of transportation are unclean and impurities are mixed into the borax, its purity will be affected; and if the seal is not good, in case of rain and fog on the way, the borax absorbs moisture, and all previous efforts will be wasted. And when transporting, it should be separated from acids, alkalis and other chemicals. Because borax encounters acid and alkali, it is easy to chemically react and cause deterioration and failure.
In short, borax should not be ignored in storage and transportation, drying, cooling, ventilation, light transportation, and isolation, so as to maintain the quality of borax and make it useful in various fields.

In today's market, the price of borax is still uncertain, due to the intertwining of many factors, resulting in fluctuations in its price range. Borax has a wide range of uses and is used in metallurgy, chemical industry, medicine, and glass industries. Changes in demand often lead to fluctuations in prices.
In terms of its price, in the past market, the price per ton or around 1,000 yuan, but this is not a constant number. When demand is strong, such as the glass industry is booming, the demand for borax increases sharply, and its price also rises, or can reach thousands per ton. In case of industry downturn, demand decreases sharply, and prices also decline.
Furthermore, the abundance of raw materials, the entry of processes, and the orientation of policies are all key to affecting the price of borax. If raw materials are abundant, the cost will decrease and the price will also decrease; if new technologies enter, the production efficiency will increase, and the price may change. If policies encourage its production, the price may stabilize or decrease; if restrictions are imposed, the price may increase.
In addition, the state of the global economy and the situation of trade are also related to the price of borax. If the global economy is prosperous, all industries will prosper, the demand for borax will be prosperous, and the price will be high. Trade barriers will increase, circulation will be blocked, and prices will also be disturbed.
To sum up, the market price of borax often changes due to supply and demand, raw materials, processes, policies, economy and trade. To know the exact number, it is necessary to look at the market state and study various factors in detail.
