8-quinolinecarboxylic acid, 3,7-dichloro-

The physical properties of 8 + -boric acid and 3,7-dioxide are also unique.
Boric acid, usually white crystalline powder or colorless scales with a pearl luster. Its taste is slightly sour and sweet, and it feels greasy to the touch. It is soluble in water, and its aqueous solution is weakly acidic. This property is derived from the fact that boric acid interacts with water molecules in water, accepts hydroxide ions, and then releases hydrogen ions, which makes it acidic. When boric acid is heated, it will gradually lose water, first forming metaboric acid, then tetraboric acid, and finally boron trioxide. It has a wide range of uses. In the glass industry, it can increase the heat resistance and transparency of glass. In the field of medicine, it has the effect of disinfection and anti-corrosion. In the leather industry, it can be used as a preservative.
As for 3,7-dioxide-, it is not detailed what it refers to. If it is a dioxide, its properties are also diverse. Take carbon dioxide as an example. It is a colorless and odorless gas at room temperature and pressure. Its density is higher than that of air. It can dissolve in water to form carbonic acid and is weakly acidic. Carbon dioxide does not support combustion and cannot be used for respiration. In nature, it is an important part of the carbon cycle. Plants absorb it through photosynthesis, while biological respiration and fossil fuel combustion release it. And if silicon dioxide is a hard and refractory solid with stable chemical properties, it does not react with most acids except hydrofluoric acid. It is commonly used in the manufacture of glass, ceramics, semiconductor materials, etc.
Most of the various compounds have different chemical properties due to their unique structures and play important roles in different fields.

The main uses of 8 + -boric acid, 3,7 -dioxy - have many aspects.
Boric acid has shown a variety of uses in ancient times. In the field of medicine, it has the effect of disinfection and antiseptic. It is recorded in ancient books such as "Compendium of Materia Medica", which can be used to treat sores, red eyes, swelling and pain. Taking sores as an example, an appropriate amount of boric acid is prepared into a solution to clean the affected area, which can inhibit the growth of bacteria and promote wound healing. Because boric acid is weakly acidic, it can create an environment that is not conducive to the growth of bacteria and play a disinfection role.
In the glass manufacturing industry, boric acid is crucial. It can improve the thermal stability and chemical stability of glass. In ancient glazing firing techniques, although the name boric acid is not explicitly mentioned, boron-containing minerals may have been used in actual operation. After adding boric acid, glass products can better withstand temperature changes, are not easy to break, and have stronger resistance to chemical erosion, making the fired glazing utensils more exquisite and durable.
3,7-dioxy-Although the specific substance is not specified, it is inferred from the common use of similar chemical structures. In the field of organic synthesis, it is often used as an intermediate. Through a series of chemical reactions, it can be converted into complex organic compounds with specific functions. In fragrance synthesis, it can be used as a starting material to construct fragrance molecules with unique aroma structures through multi-step reactions. Although there is no modern concept of fine organic synthesis in ancient times, similar structural substances or natural product components indirectly participate in the aroma formation process in the extraction and simple processing of natural fragrances. In the preparation of dyes, it can be used as a key fragment to construct the molecular structure of dyes, endowing dyes with good dyeing performance and color stability.

"Tiangong Kaiwu" is a scientific and technological masterpiece written by Song Yingxing in the Ming Dynasty, and the book contains various process technologies in detail. Regarding the preparation method of 8 + -borofluoric acid and 3,7 -dioxide -, although ancient books do not have such accurate descriptions as modern ones, according to its principles and the wisdom of the ancients, one or two can be inferred.
Preparation of borofluoric acid, in the era of "Tiangong Kaiwu", although there is no name of "borofluoric acid", the reaction principle of borax and hydrofluoric acid may have a similar idea. The ancients may have discovered some boron-containing ores, which were calcined, milled and other processes to obtain boron oxides. Then fluoroacids (such as acids extracted by the ancients from certain minerals or plants, which have a certain acidity and can react with borides) react with them. For example, the boron-containing ore is first placed in a crucible and calcined at high temperature over charcoal fire to change the ore structure and make it easier to react. After grinding into powder, mixed with appropriate acid, in a closed container, controlled according to heat and time, or a substance similar to borofluoric acid can be obtained. This process requires fine control of temperature and the proportion of raw materials. The ancients constantly explored and optimized based on experience and observation.
3,7 - Dioxide -, if it is prepared as dioxide, the ancients often obtained it by oxidation reaction. Such as metal oxides, it is mostly heated by metal and reacted with oxygen in the air. If it is a non-metallic oxide, take sulfur dioxide obtained by burning sulfur as an example, put sulfur in a well-ventilated stove, and burn it fully after ignition. Sulfur and oxygen combine to form sulfur dioxide. For complex dioxide, the raw materials are mixed first and then roasted at high temperature. For example, some compounds containing metals and non-metals, under high temperature, each element reacts fully with oxygen to form corresponding dioxide. This process requires strict conditions such as raw material purity, roasting temperature, time, and ventilation. The ancients have long practiced and mastered many skills to achieve the desired product.

8 + -Boric acid, 3,7 -dioxide- have the following precautions during use:
Boric acid is mild in nature, but it should be treated with caution. Although it is often used in many fields of medicine and chemical industry, it should not be eaten by mistake. If you accidentally enter it, rinse your mouth with a lot of water as soon as possible and seek medical treatment. And boric acid has a certain irritation. When it comes into contact with the skin, it may cause allergic discomfort. If it comes into contact with the skin, remove the contaminated clothes and rinse with a lot of water. When using it in experiments, the operation room should be well ventilated to avoid inhalation of dust.
As for 3,7 -dioxide, the properties of this substance may vary depending on the specific composition. If it is a chemical preparation, you must read its instructions carefully to understand its chemical properties and hazards. When storing, choose a suitable environment according to its characteristics, keep away from fire and heat sources to prevent danger. When using, be sure to use special appliances and operate according to specifications to avoid direct contact. The place of use should be equipped with emergency treatment equipment, such as eye washers, first aid kits, etc., for emergencies. And the operator needs to be professionally trained, familiar with the operating procedures and emergency response methods, so as to ensure the safety of the use process.

In the past, doctors relied on it to treat various diseases, such as wind and dampness paralysis, pain in the waist and knee, and each had a good effect. Looking at the market today, there is a product of Panax notoginseng, which is called the genus of dioxy. At this moment, the market prospects of these two are particularly observable.
