Smell its smell, unburned, and then disperse a special fragrance, mixed with the fragrance of grass and trees, and the fragrance of the soil. This fragrance is subtle and deep, and it is difficult for people to explore.
Furthermore, its density is low, and it is placed in the palm of your hand, which feels rich. Compared with a heavy object, it has its own beauty. And it is absorbent. If it is in the tidal environment, it is easy to absorb water vapor, resulting in the melting of the ground. Therefore, it needs to be properly preserved and placed in a dry place to maintain its original physical properties.
The material rationality, shape, color, texture, taste, and even density, absorption, etc., all exhibit their own unique characteristics, which are worthy of study and taste.

Lead and mercury medicinal pills are medicines refined by ancient alchemists to seek longevity. Its chemical properties are quite complex and have many characteristics.
Lead is heavy and soft, with a silver-gray color. In the refining of medicinal pills, it often combines with other substances. Lead is stable, but it is calcined in case of fire. It is easy to oxidize with oxygen to form lead oxides. The properties of this oxide are also different, such as color or change, and the chemical activity is also different. Lead is relatively stable in water, but in acid, it is easy to chemically react and gradually dissolve in it.
Mercury is liquid at room temperature, with a metallic luster and good fluidity. Mercury is volatile and can gradually turn into mercury vapor in the air, which is toxic. Mercury can form amalgam with a variety of metals. If it is combined with lead, its properties will also change. When mercury is heated, it can react with oxygen to form mercury oxide, and its color changes from silver to red.
Lead and mercury medicinal pills involve a variety of chemical reactions. During refining, high temperatures make lead and mercury interact with other medicinal materials. Lead and mercury combine with each other, or react with sulfur and other substances. Sulfur is dry, combined with lead and mercury, or drastic changes in the properties of medicinal pills. After repeated calcination, grinding, combining and other processes, it eventually becomes an medicinal pill.
However, although lead and mercury medicinal pills are ancient and seek longevity, they are regarded as treasures and contain highly toxic. Lead and mercury are difficult to metabolize in the human body and accumulate in the body, damaging the organs, messing with qi and blood, and hurting nerves. Ancient medicinal pills caused illness and death. Later generations knew its harm, gradually abandoned this technique, and turned to other methods for health care.

The following inquiries are related to the common reactions of dimethyl ether. Dimethyl ether has peaceful properties and is widely used in chemical engineering.
First, in catalytic oxidation reactions, dimethyl ether is often used as a substrate. Because dimethyl ether contains hydrocarbon bonds and ether bonds, under suitable catalysts and conditions, its hydrocarbon bonds can be broken, and oxygen atoms are involved to form oxygen-containing compounds such as formaldehyde and formic acid. This reaction is of great significance in the preparation of fine chemical products. For example, formaldehyde is a basic raw material for the synthesis of many resins and is indispensable in building materials, textiles and other industries.
Second, the reforming reaction of dimethyl ether with water vapor is also common. In this reaction, dimethyl ether and water are catalyzed to generate hydrogen and carbon dioxide through a series of complex steps. Hydrogen is a representative of clean energy, and this reaction is one of the ways to produce hydrogen. It has potential value in the energy field, which can help the development of hydrogen energy and alleviate the current energy and environmental dilemma.
Furthermore, the carbonylation of dimethyl ether should not be underestimated. In a specific catalyst and environment, dimethyl ether interacts with carbon monoxide to form methyl acetate. Methyl acetate is an important organic chemical intermediate, which can be further converted into acetic acid, ethanol, etc., and is a key node in the organic synthesis industry.
There is also the reaction of dimethyl ether and olefins. Dimethyl ether can be combined with olefins such as ethylene, propylene, etc., under specific conditions, through a catalytic process, to generate high-value-added chemicals, such as alkylation products, which can be used in the field of oil additives to improve oil quality and optimize its combustion performance.
In summary, dimethyl ether is a commonly used reactant in catalytic oxidation, steam reforming, carbonylation, and reaction with olefins. It plays a key role in many fields such as chemical industry and energy, and promotes the development and progress of the industry.

The method of synthesis of the methyl group mentioned in 2-% E7% A2% 98 is described in the "Heavenly Materials".
"Heavenly Materials". Where armor is made, its initial quality is good. The fine one is melted into a plate, and the thickness can be divided. The method of its smelting is to seek the best way to mix it. When the plate is completed, it is large and dense, so that the density of the ground is increased.
When it is made in the first place, it is made of high-quality materials. The shape of its shape is straightened and high-quality, so as to be safe.
Especially in the manufacture of high-quality armor. With high-quality alloys, fused in a certain proportion. The addition of rubber can make the rubber more hard. The molten liquid is put in a carefully made mold and ready to be cold-formed. After forming, it is added and polished to make it convenient, and there are special holes or holes at its tail end.
It is placed on the mold, bonded with force, and then reinforced with a hoop, so that the two can be firmly connected and will not fall off.
The reason why the mold can be made is because of its special shape. The hole at the tail end of the mold, when it is used, is penetrated in the air, forming a special flow vibration, so it is produced. This is ingenious, which not only has the function of the machine, but also can be used to warn or inform, which is the essence of ancient weapons. The method of synthesis involves the profound understanding and wisdom of the ancients in materials, workmanship and function.

2-% E7% A2% 98 The methyl layer mentioned above is used in the field of application.
In the realm of sacrifice and prayer, the methyl layer has an important meaning. Ancient sacrifices were a grand event of worshiping gods and ancestors and praying for blessings. With its unique characteristics, methyl layer is like being able to communicate with the gods. In the sacrificial ceremony, it starts from the beginning, and the sound is slow, and it diffuses in the sacrificial hall, so that the hearts of the worshippers are in awe, and the gods are sent down, helping the sacrifice to achieve the purpose of communicating with the gods, so as to pray for the year and get rid of it.
In the event of conquest, the methyl layer also plays an important role. On the way, it can be used to refer to the letter. With its different performances, attack, retreat, set and other instructions. In the same way, it is like an arm holding the finger, so that the transportation is orderly and orderly. On the top of the mountain, its performance can be more uplifting, so that our scholars can be high-ranking, and the same party can be prosperous, frustrating.
Furthermore, the combination of the code, the methyl code can add the atmosphere. Such as the joy of the harvest, the ascension of the new king and other major ceremonies, their grandeur, the crowd, and the style complement each other, rendering a joyous and peaceful atmosphere, making the ceremony more important, uniting people's hearts, and recognizing the image of the prosperous world.
In addition, the methyl code has an unavoidable role in various fields such as sacrifices, affairs, and transportation, and has become an indispensable element in ancient social life.
