What is the main use of (1z) -1,2,3,3,4,4,4-heptafluoro-1-iodobutyl-1-ene?
"Tiangong Kaiwu" is a scientific and technological masterpiece written by Song Yingxing in the Ming Dynasty, covering many fields of knowledge. Looking at the expression " (1z) -1, 2, 3, 3, 4, 4 - Qihe - 1 - Question 1 - 1 - Heat", it seems unclear, but based on the breadth of "Tiangong Kaiwu", it may be possible to speculate one or two.
The book details various production technologies, among which the "heat" of fuel is widely used. For example, in the art of smelting and casting, coal, charcoal, etc. are used as heat sources, and the "heat" generated by them is used to melt metal ores and then cast them into required utensils. In this process, the heat of fuel is the key driving force for converting ores into usable metals, which is related to the efficiency and quality of casting.
In the art of pottery making, the kiln needs to use heat to fire the pottery blank. The appropriate heat, heating and cooling rhythm determine the texture, color and quality of the pottery. "Heat" here becomes the core element of shaping the characteristics of pottery. If the temperature is not properly controlled, the pottery may have defects.
When making paper, "heat" also plays an important role. The cooking raw materials need a certain heat to soften and decompose the fibers for subsequent papermaking processes. The rational use of heat can improve the fiber extraction efficiency and paper quality.
Even if expressions such as "Qihe" and "Question 1" are difficult to understand exactly, "Tiangong Kaiwu" regards "heat" as a key driving force and condition in many process links, promoting various production activities, which has a profound impact on the development of traditional handicrafts, and is an indispensable element for realizing material transformation and making utensils.
What are the physical properties of (1z) -1,2,3,3,4,4,4-heptafluoro-1-iodobutyl-1-ene
"Tiangong Kaiwu" is an important ancient book on agricultural and handicraft production technology in our country. In response to the question " (1z) - 1, 2, 3, 3, 4, 4, 4 - Qihe - 1 - Question 1 - 1 - What are the physical properties of heat", the answer is as follows in ancient classical Chinese:
The physical properties of heat are particularly important. First, heat can cause changes in the state of matter. If ice is heated, it melts into water, and when water is heated, it turns into steam. This is the sign that heat converts matter from solid to liquid and then to gas. This phenomenon is common in the world, and the ancients have long observed it. Gold is melted in a furnace fire, and gold is heated from solid to liquid, and can be cast into a tool.
Second, heat has the property of conduction. Put the iron chopsticks in the fire, one end is heated, and soon, the other end is also gradually heated. This is the reason why heat conduction is conducted by iron chopsticks. Different materials have different heat conductivity. Metals are mostly good conductors, and heat transfer is very fast; wood, pottery, etc. conduct slowly, which can be used for heat insulation.
Third, heat has the effect of expansion. All kinds of objects, most of them expand when heated. In the past, the system of observing the wheel was heated on the rim to make it expand, and then put it on the hub, and when cooled and contracted, the two fit tightly, and the car was stable. This is the principle of thermal expansion.
Fourth, heat is related to temperature. The amount of heat is reflected in the temperature. The direction of heat transfer, from high temperature to low temperature, until the temperature of the two is equal. For example, in winter, Mrs. Tang is used for warmth. The temperature of Mrs. Tang is high, but the temperature of her hands is low. Heat is transmitted from Mrs. Tang to her hands, and people feel warm.
To sum up, heat has physical properties such as changes in the state of matter, conduction, expansion, and temperature. It has a significant impact on the change of all things and the skills of all kinds of workers. The ancients also understood and applied it in their daily work and life.
What are the chemical properties of (1z) -1,2,3,3,4,4,4-heptafluoro-1-iodobutyl-1-ene
"Tiangong Kaiwu" is a scientific and technological masterpiece written by Song Yingxing in the Ming Dynasty, which records many scientific and technological contents in classical Chinese. Today's answer in a format similar to classical Chinese is as follows:
Fu " (1z) - 1, 2, 3, 3, 4, 4 - Qihe - 1 - Question 1 - 1 - Heat" The chemical substances involved should have a variety of characteristics. First, its physical properties may have specific colors, such as red, green, yellow, white, and black; it also has a unique state, either solid, solid and touchable; or liquid, flowing and invisible; or gas, ethereal and difficult to detect. Its taste can be either pungent, sour, sweet, bitter, or salty.
As for chemical properties, flammability is one of them. In case of open flame, hot topic, or can burn violently, releasing light and heat, this is related to the reaction characteristics of fire. Stability is also critical, or under normal temperature and pressure, its quality can be unchanged for a long time; in case of special conditions, such as strong acid, strong alkali, high temperature, high pressure, or violent changes.
Furthermore, its redox property cannot be ignored. It can react with oxidants and be oxidized by itself; it can also react with reducing agents and be reduced by itself. And the characteristics of acid and base can be neutralized with acids and bases, forming different substances and changing chemical compositions and properties.
Or it has catalytic properties. In some chemical reactions, although it is not consumed, it can change the rate of chemical reactions and speed up or slow down the process of reactions. It is a miraculous quality. Such various chemical properties play a crucial role in the change and application of substances.
What is the synthesis method of (1z) -1,2,3,3,4,4,4-heptafluoro-1-iodobutyl-1-ene?
"Tiangong Kaiwu" is a scientific and technological masterpiece written by Song Yingxing in the Ming Dynasty. Today, the classical Chinese genre is used to answer your question.
If you want to make this thing, first take good materials. First, choose the best material, and its quality is pure and strong. If you make utensils, you must choose tough wood or refined metal. This is the foundation.
The second time is the technique. If you use wood as the base, you should cut it with a saw, and measure it accurately according to the shape you need. If it is a metal, it needs to be melted and calcined with fire to make it flexible and malleable. During this period, the heat is very important. If the fire is fierce, it will be brittle, and if the fire is weak, it will be difficult to form.
When mixing, according to its proportions. Taking the mixing of medicines as an example, the exact number must be followed, and it is not bad at all. The ingredients are combined, or stirred evenly, or made to penetrate each other, in order to achieve their effect.
Furthermore, it is tempered through multiple processes. Or beating to increase its density, or drying to determine its shape. During this period, observe carefully and adjust the techniques and steps in a timely manner. In case of difficulty, you need to try again and again to find the best way.
When operating, the craftsman's heart needs to be as thin as hair, focus on concentration, and not slack in the slightest. If there is a slight mistake, all previous efforts will be lost. And every step needs to follow ancient methods and experience, and at the same time, it can also be timely to innovate to achieve perfection. Only in this way can we obtain what we need to achieve a masterpiece.
What is the price range of (1z) -1,2,3,3,4,4,4-heptafluoro-1-iodobutyl-1-ene in the market?
"Tiangong Kaiwu" says: "All things in the world have their own price, and the price is high or low, which is related to supply and demand, materials, craftsmanship, etc." Today, when discussing the price range of flames in the market, many factors need to be considered.
Flames are unusual things that can be sold, but in specific situations, such as fireworks shows, special crafts, etc., there is a cost to acquire or use them. If it is a flame of ordinary fireworks, the cost of materials such as gunpowder and production process requirements are not very high, and the supply is relatively sufficient. Although it is not measured by pure price, if the analogy is based on materials and manpower, the cost of each use may be between a few dollars and two taels of silver.
And if it is a special purpose fire such as alchemy, the requirements for the flame are extremely strict, or special venues and special fuels are required to create a specific flame, which is expensive. Fuel or rare things, the construction and maintenance of the venue also requires a lot of material and manpower, so the cost may reach tens of taels or even hundreds of taels of silver.
Furthermore, if it is in a situation such as a magic performance, the appearance of the flame depends on unique skills and props. Although the flame is invisible, the cost of materials and skills required behind it may make its "value" equivalent to the consumption of two to ten taels of silver.
However, these are all speculative analogies. In fact, it is difficult to accurately price the goods that are not traditionally traded in flames. Only based on the ancient concept and the possible costs involved, the price range is roughly the same.
