What are the main application fields of aluminum trifluoromethanesulfonate
Arsenic trisulfide, or realgar, has a wide range of main application fields.
In the field of medicine, realgar has the effect of detoxifying insects, removing phlegm from dryness and dampness, and intercepting malaria. "Compendium of Materia Medica" says: "Realgar is an essential medicine for treating sores and detoxifying toxins." Ancient physicians often used it to treat scabies, carbunx, snakeworm bites and other diseases. For example, "Erwei Detoxification Powder" in "Authentic Surgical", which uses realgar and alum to study the fine powder together, and apply it with tea to treat all yang swelling and poison, and has the power of detoxifying and reducing swelling.
In traditional folk customs, realgar is also important. During the Dragon Boat Festival, there is a folk custom of drinking realgar wine and painting realgar on children's foreheads, in order to exorcise evil spirits and avoid plague. Legend has it that Bai Su Zhen, a white snake, drank realgar wine on the Dragon Boat Festival and took its original form. Although this is a myth, it reflects the symbolic significance of realgar in folk culture to remove filth and exorcise evil spirits.
In industry, realgar can be used as a pigment. Its color is bright orange and yellow, and it may be useful for ancient paintings, ceramics, etc. For example, the color of Dunhuang murals, or containing realgar ingredients, is still bright and moving after years. And in the metallurgical industry, realgar can be used as a raw material for the extraction of arsenic and the manufacture of arsenide.
Furthermore, in religious and sacrificial activities, realgar often appears The ancients believed that it had mysterious power, could use the gods and exorcise ghosts, so it was used in sacrificial ceremonies to pray for peace and well-being.
What are the physical properties of aluminum trifluoromethanesulfonate?
Arsenic trisulfide, or realgar, is a common mineral. Its physical properties are unique and worth mentioning.
The color of realgar, often orange-red, is bright and eye-catching, and it is impressive to look at. Its color is rich and vivid, and it is unique among minerals, so it is easy to identify. Its luster also has characteristics, mostly from diamond luster to grease luster. Under the light, it may be bright or warm, depending on the environment and viewing angle.
When it comes to hardness, realgar is relatively low, with a Mohs hardness of about 1.5 to 2, and a slightly softer texture. This property makes it easier to leave traces when carving or carving. When scratched lightly with fingernails, or can leave marks, the difference is obvious compared with many hard minerals.
Its density is moderate, about 3.56 g/cm3. Holding in the hand, you can feel a certain amount, but it is not heavy.
The crystal shape of realgar is usually columnar, short columnar or needle-like, and the crystal shape is complete, which is quite beautiful. However, in nature, it is also often produced in bulk and granular aggregates.
Furthermore, realgar is brittle and easy to break into small pieces or powder when hit by external forces, which is one of its physical properties.
In addition, realgar has a certain degree of transparency, and some realgar specimens can be transparent and translucent in thin or small pieces, adding to their unique charm. All kinds of physical properties together create the characteristics of realgar, which is of great significance in the fields of mineral research and traditional applications.
How is the chemical stability of aluminum trifluoromethanesulfonate?
The chemical stability of trimethylformate sodium copper depends on its structure and its environment. The stability of this complex is related to the solidification of its internal bonds and the disturbance of external factors.
Looking at its structure, copper ions are connected to the group of sodium formate by coordination bonds. Coordination bonds are used by electrons to form bonds, and their strength makes the complex stable. In sodium formate, carboxyl groups can coordinate with copper ions to form a stable structure. If the coordination structure is compact and the spatial resistance is suitable, it can prevent the invasion of external particles, and its stability is high.
And the temperature, humidity, acid and alkali of the environment affect its stability. At room temperature, the bonds in the complex can maintain their state. If the temperature rises sharply, the vibration of the bond will intensify, or the bond will break and the complex will change. As for humidity, water vapor can enter the lattice, breaking its original interaction and damaging its stability. And the acid-base environment is particularly critical. In acidity, protons can interact with ligands, seize their electrons, and break coordination bonds; in alkalinity, hydroxide ions or react with copper ions, which also damages the stability of the complex.
To increase its stability, you can choose suitable ligands to strengthen coordination bonds in structure; in the environment, temperature control, humidity control, and retinoic acid-base adaptation. In this way, sodium copper triformate can achieve good chemical stability, maintain its inherent properties, and is not easily changed.
What are the precautions for storing and transporting aluminum trifluoromethanesulfonate?
Triacetic acid should be paid attention to in general matters.
If it is stored, it will be the first to cause dryness in the environment. Because of its absorbency, if it is in the place of moisture, it is prone to deliquescence, which will cause its chemical properties to become unhealthy and affect the quality of the product. It is advisable to avoid dry and well-connected rooms, and the degree of the room should be kept stable, not strong.
Furthermore, avoid the mixing of acids, chemicals and other substances. Triacetic acid is easy to produce acetic acid when it encounters acid, and may be biochemically reacted and destroyed when it encounters it. Therefore, it is necessary to store this material separately and determine the storage area of the product for safety.
It is necessary to cover the package. Use packaging materials that meet the requirements of the phase, and keep them in the process. It is not necessary to break the packaging due to factors such as earthquakes and collisions, resulting in the exposure of triacetic acid.
Tools also need to be kept clean and dry, and no other chemicals should be left behind to prevent the reaction of triacetic acid. On the way, people and people should be familiar with its characteristics and emergency treatment methods. If there is an emergency, they can quickly and properly deal with it.
In addition, it is necessary to pay attention to the road, avoid densely populated areas and environment-sensitive areas, and reduce the possible harm caused by accidental hygiene. In this way, the survival and safety of triacetic acid can be guaranteed.
What are the preparation methods of aluminum trifluoromethanesulfonate?
The method of making copper acetate in Sanxiang has many wonderful recipes, which are described in detail below.
First, it is made of copper and vinegar. Take an appropriate amount of refined copper, put it in a clean container, pour it into rice vinegar, and immerse the copper. Rice vinegar, containing acetic acid, can gradually react with copper. The container should be open and placed in a ventilated and shimmering place, but it should not be exposed to the hot sun. After ten months, acetic acid and copper slowly react, copper gradually dissolves, the liquid turns light green, and then turns into light blue, which is the gradual appearance of copper acetate. This process must be patient and not impatient. Because the reaction is slow, to obtain pure products, it is necessary to wait for the liquid color to be stable and there is no copper left.
Second, it is made of copper oxide and acetic acid. Take the copper oxide first, which can be obtained by burning the copper in the air. Break the copper oxide into a fine powder, place it in a porcelain dish, and slowly inject the acetic acid solution. The concentration of acetic acid should be appropriate, not too concentrated, so as not to overreact. When the two meet, they will react, and bubbles will escape, and the liquid color will gradually change. During this time, it is often stirred with a glass rod to promote a uniform reaction. When the bubbles stop, the liquid color is fixed, and the copper acetate solution is obtained. After evaporation, concentration, cooling and crystallization can be obtained. When evaporating, the heat should be stable, not too hasty, to prevent crystal decomposition.
Third, it is made of copper sulfate and sodium acetate. Take an appropriate amount of copper sulfate and sodium acetate and dissolve them into a solution respectively. The copper sulfate solution is blue, and the sodium acetate solution is colorless. Slowly pour the sodium acetate solution into the copper sulfate solution, and stir while tilting, and there is a gradual precipitation. This precipitation is copper acetate. After the precipitation is completed, filter it with filter paper to obtain the precipitation. Then polyester it with distilled water to remove impurities, and then place it in an oven to dry at a suitable temperature to obtain pure copper acetate.
This method has its own advantages and disadvantages. It is made of copper and vinegar, and the raw materials are easy to obtain, but it takes a long time; the method of copper oxide and acetic acid reacts quickly, but the preparation of copper oxide is slightly more complex; the method of copper sulfate and sodium acetate, the operation is slightly more complicated, but the product is easy to purify. When choosing a law, it depends on the situation in order to achieve the best results.
