8-Quinolinecarboxaldehyde

8 - Calciferite is a mineral with special physical properties in nature. Its shape is tetragonal crystal system, and the crystal is often tetragonal double cone, or granular, block-like aggregate. It has a regular geometric shape, just like a natural workmanship.
As far as its color is concerned, it is mostly colorless, white, and occasionally light gray, light yellow, light red and other colors. The color is simple and elegant, as if it contains a simple charm between heaven and earth. Its luster is as bright as glass, and under the light, it flickers slightly, seeming to have a hidden charm.
8 - The hardness of calciferite is about 5 to 5.5, and the texture is relatively solid, which can resist a certain degree of friction. Its density is between 2.2 and 2.3 g/cm3, and it feels light and heavy, without feeling too light or heavy.
In addition, 8-cubezolite has good water absorption. When placed in a humid environment, it can absorb water vapor, as if it can sympathize with water vapor between heaven and earth. When heated, its internal moisture escapes, and a phenomenon similar to boiling occurs, hence the name "zeolite". This wonderful property is like a unique spirituality bestowed by heaven.
In addition, 8-cubezolite also has ion exchange properties. In a specific chemical environment, the internal ions can be exchanged with the ions in the surrounding medium, which makes it potentially useful in many fields, or can be used for water purification, or can play a unique role in chemical production. It is a mineral that cannot be underestimated, showing the wonders of natural creation.

8 - Calcite is a mineral with special chemical properties. Its chemical properties are as follows:
First, it is ion-exchangeable. The crystal structure of calcite contains exchangeable cations, such as sodium, potassium, calcium, etc. Under suitable conditions, these cations can be exchanged with other cations in the surrounding environment. This property is crucial in the field of water purification and soil improvement. For example, during the softening process of hard water, calcite can exchange calcium ions in the water, reducing the hardness of water. This principle is similar to the ancient method of replacement, replacing the original ions with other substances, so that the water quality can be improved.
Second, it is adsorbent. The internal porous structure of calcite gives it good adsorption capacity, which can absorb impurities and harmful substances in gases and liquids. Just like the ancients used fabrics to filter out debris, calcite can adsorb heavy metal ions and organic pollutants in water, and can also adsorb harmful gases in the air, playing an important role in environmental protection.
Third, acid resistance. Calcite is resistant to a certain degree of acid. Although it can react in strong acids, it is more stable in weak acid environments than many minerals. This property makes calcite suitable for industrial production in some acidic environments. For example, as a catalyst carrier in specific chemical reactions, it is not easily eroded by acidic substances and maintains the stability of the reaction. It is like a solid foundation that supports the development of the reaction.
Fourth, it is thermally stable. At higher temperatures, the crystal structure of calcite can remain relatively stable, which makes it useful in high-temperature industrial applications, such as in the manufacture of high-temperature furnace insulation materials, which can withstand high temperatures without easily deforming or decomposing, similar to the ancient heat-resistant barrier, blocking the invasion of high temperatures.

8 - Calciferite is one of the zeolite group minerals. The common synthesis methods are as follows:
- ** Hydrothermal synthesis method **: This is a commonly used method. Select suitable silicon sources, aluminum sources, alkali sources and templates. For example, sodium silicate is used as the silicon source, sodium metaaluminate is used as the aluminum source, sodium hydroxide adjusts the basicity, and tetrapropyl ammonium hydroxide is used as the template. Mix the raw materials in a specific ratio to form a uniform gel. For example, the ratio of silica to aluminum, alkalinity, and water content all need to be precisely regulated. Then, the gel is placed in an autoclave and crystallized at a suitable temperature and autogenous pressure. Generally, the temperature is between 100 and 200 degrees Celsius, and the time varies from a few hours to several days. After the crystallization is completed, the product is centrifuged, washed and dried to obtain 8-calciferite. During this process, temperature and time have a great impact on the growth and morphology of crystals. If the temperature is too low, the crystallization is slow; if the temperature is too high, crystal defects may occur.
- ** Microwave synthesis method **: The hydrothermal synthesis is the basis and takes advantage of microwave heating. After the raw material is prepared into a gel, it is put into a microwave reaction device. Microwave heating is fast and uniform, which greatly shortens the synthesis time. Compared with the traditional hydrothermal method, microwave synthesis can complete the crystallization in tens of minutes, and the resulting crystal particle size is uniform and the crystallinity is good. However, the equipment cost is higher, and the control requirements for reaction conditions are also more stringent. < Br > - ** Dry glue method **: Prepare xerogels containing silicon and aluminum raw materials without adding a lot of free water. The xerogel is placed in a reactor containing a small amount of water vapor and crystallized at a certain temperature and pressure. This method uses less water, has low energy consumption, and can avoid crystal agglomeration caused by the presence of a large amount of water, resulting in good dispersibility of 8-calciferite. However, the xerogel preparation process requires fine operation to ensure uniform distribution of each component, otherwise it will affect the quality of the final product.

8 - For those who are in the right place, their nature is like the damp, and they are afraid of the cold and the heat. Therefore, the way to hide is to seek to suit their nature.
Those who hide this kind of damp, the first place to hide. It is appropriate to make a place that is dark, transparent and dry. The dark is in line with its nature of avoiding light, and it can make the air flow, so that it will not be damaged. The damp can avoid the harm of its tides. If it is damp, it is easy to get sick, and the limbs are rotten, and their lives will not be long.
For the second time, the degree of damp is very important. This is not resistant to high temperatures, and it is hot in summer, and it is suitable to be placed in a cool place. A deep well can be dug in the room, and the wellhead should be placed in the well, and the damp can be hidden in it, so that the ground can be used to save In the cold of winter, it is cold and cold, and it needs to be wrapped in a cloth, or placed in a warm place, but it should not be too close, for fear of being scorched by fire and causing it to burn to death.
Furthermore, the supply of food also needs to be paid. 8 - Fang Mingjia uses rotten wood and rotten wood to eat, and gathers the food, and it must be new and new. And the amount of food should be in the middle, not too much, more perishable, and polluting the habitat; nor should it be less, less, and weak.
Also, its habitat is suitable. Regularly remove stool and rotten food to prevent the growth of germs. If there is a problem, such as doing the problem, changing the color, observing it, and understanding its cause, or isolating it, or treating it, so as not to cause damage to the group.
Those who are hiding 8-Fang Mingjia need careful care, according to their characteristics, dryness, and difficulty, proper food supply, and poor housing. In this way, they can survive and multiply.
