Both are in the process of industrial production and scientific research, and each has its own capabilities. They have made great contributions to the development of chemical industry, materials, medicine and other fields, and occupy an indispensable position in many application scenarios.

No. 6 of Sanxiang Jiadi - and No. 4 of the Quartet Light Armor Leech -, the physical properties of the two are different.
Sanxiang Jiadi, its quality is strong and tough, like the genus of gold and stone, although it has been eroded by wind and rain, it is difficult to damage its shape. Its color is dark, just like the dark color of night. Under the dim light, there is a faint light flowing, just like the spirit of the dark night. The touch is slightly cool. When you start, if you encounter cold jade, you will feel a warm and moist meaning gradually emerging, as if it is in harmony with human body temperature.
The Quartet Light Armor Leech, its shape is soft and elastic, like a weak willow to support the wind, shapes with objects. The color is like the beginning of the morning glow, gorgeous and bright, dazzling, looking at it from a distance, like Qixia falling on the world. To touch it is greasy as fat, like silk caressing the skin, cool and refreshing, but without a piercing feeling. Under the light, it can especially reflect multicolored rays of light, beautiful, like a dreamland.
Sanxiang Jiadi, calm in nature, can ward off evil spirits in the house. Together with feng shui, it is very beneficial. It is often placed in the living room for the world to seek stability and harmony. The four-sided light armor leech is flexible and changeable, with the effect of healing wounds and diseases. The ancient healer often took it as medicine to relieve the pain of the world. Although the two have very different physical properties, they are both rare wonders in the world, each has its own use, and both have unique value between heaven and earth.

The synthesis of 6 - (triethyl) - 4 - p-methoxyphenylacetonitrile is an important topic in the field of organic synthesis. Although Guanfu's ancient book "Tiangong Kaiwu" did not directly describe the synthesis of the two methods, its concept in chemical creations may provide inspiration for today's synthesis ideas.
If you want to synthesize 6 - (triethyl) now, you can follow the following routes. First, take a suitable olefin as the starting material and use an addition reaction to introduce triethyl groups. If an olefin is selected, under the action of a specific catalyst, it will be added with a reagent containing triethyl methyl. This process requires careful selection of catalysts, and its activity and selectivity depend on the success or failure of the reaction. And the reaction conditions such as temperature and pressure also need to be precisely regulated. If the temperature is too high or the side reactions increase, if it is too low, the reaction rate will be slow.
As for the synthesis of 4-p-methoxyphenylacetonitrile, p-methoxybenzene can be used as the substrate first, and the acyl group is introduced through Fu-Ke acylation reaction. After reduction, halogenation, and then reaction with cyanide reagents, 4-p-methoxyphenylacetonitrile is obtained. When Fu-Ke acylation reaction, appropriate acylating reagents and catalysts should be selected, and the anhydrous environment of the reaction system should be paid attention to, otherwise the catalyst will be easily deactivated. The reduction step also needs to choose an appropriate reducing agent to control the degree of reaction and avoid excessive reduction. The halogenation reaction requires attention to the dosage of halogenated reagents and reaction time to ensure the accuracy of the halogenation position. When reacting with cyanide reagents, it is necessary to pay attention to the mild reaction conditions to prevent the escape of cyanide and endanger safety.
Although the ancient book "Tiangong Kaiwu" does not describe such fine organic synthesis methods in detail, the spirit of exploration and the concept of focusing on practice advocated by it inspire our generation to continue to study on the road of organic synthesis, and to find efficient and green synthesis paths according to modern scientific theories and technologies.

6 - (trialkyl methyl) - 4 - square light horseshoe crabs, the need for transportation, need to pay attention to all things. These two are rare things, when it is transported in Tibet, you should be careful.
When hiding, the first environment. It is advisable to choose a cool and dry place to avoid the sun and heat insulation to prevent deterioration. If you are in a humid place, the moisture will soak it, for fear of damaging its quality and reducing its effectiveness. And you need to stay away from filth, prevent it from being stained, and keep it pure.
When it is transported, it must be especially stable. Its body is delicate and brittle, and it is not resistant to bumps. When lined with soft objects, it should be sent slowly and steadily to avoid its vibration. If you are walking on a rough road, you need to pay more attention and do not collide.
Furthermore, people are also crucial. The operator should know its nature, know its needs, and proceed with caution. Do not be careless to prevent mistakes. When handing over, you also need to check it carefully, clarify its state, and make sure it is complete before it is proper.
In short, 6- (trialkyl methyl) -4-square horseshoe crabs are important in the journey of Tibet and transportation. The environment, stability, and people are all important, and they cannot be neglected. Only by doing everything well can they be kept intact and not lose their usefulness.

Wen Jun's inquiry is about the impact of trichloroethylene and carbon tetrachloride on the environment and human health. Both are common chemicals that were used in industrial activities in the past, but they have a significant effect on the world around them and our bodies.
First of all, trichloroethylene, which is a colorless liquid with a fragrant smell. In the environment, if trichloroethylene escapes into the atmosphere, it will undergo photochemical reactions and affect the quality of the atmosphere. It is also soluble in water. If it enters the water body, it will endanger the survival of aquatic organisms. Many studies have shown that trichloroethylene can interfere with the physiological functions of aquatic organisms, causing their growth and development to be blocked, and even death. And because of its high chemical stability, it degrades slowly in the environment, easily remains for a long time, accumulates in soil and water, and continues to cause harm.
As for human health, trichloroethylene is particularly harmful. Inhalation through the respiratory tract or skin contact can cause human lesions. Common cases cause skin allergies, causing rashes, itching and other symptoms. More serious cases, it can damage important organs such as the liver and kidneys. Long-term exposure to this environment also increases the risk of cancer, especially liver and kidney cancer.
Looking at carbon tetrachloride again, this is a colorless liquid with a special odor. At the environmental level, once carbon tetrachloride is released into the atmosphere, it will rise to the stratosphere and cause damage to the ozone layer. The ozone layer is like the umbrella company of the earth. After it is destroyed, ultraviolet rays drive straight in, which is harmful to the earth's organisms. In soil and water, carbon tetrachloride is also difficult to degrade and pollutes the surrounding environment.
To the human body, carbon tetrachloride is highly toxic. A small amount of inhalation will cause dizziness, fatigue, nausea and other discomforts. A large amount of inhalation or long-term exposure can cause serious damage to the liver, causing abnormal liver function and even liver necrosis. The kidneys will also be affected, and symptoms of kidney failure will appear.
To sum up, trichloroethylene and carbon tetrachloride pose a huge threat to the environment and human health. Although they have many applications in the past, their use has been gradually restricted in view of their harm. Our generation should cherish the environment and health and treat such chemicals with caution.
