What are the main uses of 2-iodobenzothiophene?
In the era covered by "Tiangong Kaiwu", 2-nitrate (saltpeter) and alum (alum and other types of alum) were both important chemical raw materials and were widely used.
Saltpeter is mainly used in military and pyrotechnic manufacturing. In the military field, it is a key component of gunpowder. In the gunpowder formula, saltpeter is an oxidizer, which provides oxygen in the combustion reaction, causing gunpowder to burn violently and produce an explosive effect. It has a profound impact on the weapons and tactics of ancient warfare. For example, the production of all kinds of firearms cannot be separated from saltpeter, which greatly changes the mode of warfare. In the production of fireworks, saltpeter allows fireworks to produce colorful flames and explosions, which are used for celebrations, sacrifices and other activities to add a lively atmosphere.
Secondly, saltpeter is also used in the field of medicine. The ancients believed that it has the functions of clearing away heat and purging fire, diuretic and drenching, and can be used to treat some diseases such as heat syndrome and drenching syndrome. It occasionally appears in traditional Chinese medicine prescriptions.
Furthermore, saltpeter plays a role in some special industrial processing, such as metallurgy for refining metals, helping to remove impurities and improve metal purity.
Alum and other alums are significantly used in the paper industry. During the papermaking process, the addition of alum can make the surface of the paper tighter, improve the water absorption and moisturizing properties of the paper, improve the quality of writing and printing, and make the paper more suitable for writing and preservation.
In food processing, alum is often used for water purification and food preservation. When purifying water, the colloidal substances produced by the hydrolysis of aluminium can absorb suspended impurities in the water, making the water clear and ensuring the safety of drinking water. In food preservation, for example, adding alum when making fried dough sticks and other foods can play the role of leavening agent, making the food taste better, and also have a certain preservation and anti-corrosion effect.
In addition, in the printing and dyeing industry, alum is used as a mordant, which can make the dye better adhere to the fabric fibers, improve the dyeing fastness and color brightness, and make the fabric color printed and dyed more gorgeous and lasting.
What are the physical properties of 2-Iodobenzothiophene?
Saltpeter and sulphur, its physical properties can be investigated.
Saltpeter, the name of nitric acid, is often a transparent crystal of color, or a white powder. Its taste is salty and thick, and it is brittle and fragile. The solubility in water is good, and the solubility also increases with the increase of the degree. In fire, saltpeter can support combustion, and in case of combustible materials, it can make the fire more expensive. Because it is decomposed by the decomposition and releases oxygen, it is an indispensable combustion aid in the fire.
Sulphur, the color is light, and it has a special odor. It is often solid, brittle in the ground, and the melting time is not high. It is easy to melt into a liquid. Sulphur is insoluble in water, but soluble in carbon disulfide and so on. Its chemical activity can generate reaction between gold and non-gold.
saltpeter and sulfur, the two are combined in the manufacture of fire. Saltpeter provides oxygen to support combustion, sulfur can reduce the ignition of fire, making fire more easy to ignite, and the combination of the two can reduce the speed and power of fire. In the ancient fire attack, the combination of the two played a significant role, adding new means to the operation. The physical properties of the two cooperate with each other to achieve the characteristics of fire, an important chapter in the history of firearms development.
Is the chemical property of 2-Iodobenzothiophene stable?
Mercury is a heavy metal, and its chemical properties are determined.
Mercury, which is a liquid under normal conditions, is the only liquid gold. Its chemical properties are determined, and it is not easy to reduce the biochemical reaction of most substances. However, under specific conditions, such as adding water, it can generate mercury oxide by oxygen reaction. Mercury is of high quality, and it can be evaporated under normal conditions. Mercury vapor and its compounds are very toxic, and it is very harmful to humans.
, is a kind of heavy gold, and the surface is easy to form monoxide or carbonate film in the air. The film can prevent the oxidation of some parts, and to a certain extent, it is characterized by its chemical properties. It can react slowly with dilute acid, but it is soluble in sulfuric acid and nitric acid. Because of its surface, it forms a solution or oxide film, so that the reaction of the chemical compound also has a certain degree of characterization, such as carbonate, sulfuric acid, etc., which are determined in the normal phase.
However, the "determination" of the two is phase. In some special components such as oxidation and high temperature, mercury and mercury can still be reacted and reacted to generate new compounds. And because of its heavy gold properties, it can be degraded in the environment, enriched in biology, and caused by environmental protection and human health. Therefore, the chemical properties of mercury have a certain degree of characterization under general conditions, but under the action of special conditions or environmental conditions, it can also be reformed.
What are the synthesis methods of 2-iodobenzothiophene?
To make the method of combining two flavors, although it is not specifically discussed in "Tiangong Kaiwu", it can be deduced from the principles of the combination described in it.
Where the method of combining, the first raw material is selected. Arsenic is often found in stones, and it is better to distinguish its veins and texture when picking. Realgar also has its own specific origin. Its color and quality are related to the effect of the combination. Those with bright color and pure texture must be selected.
Second, it is necessary to control the heat. The ancients said: "Fire is the hub of creation." Combine the two, or bake them with a slight fire first, so that the water is exhausted and the texture is uniform. Then gradually increase the fire, but it should not be too fierce. If it is too fierce, it will be easy to scorch and lose its character. The method of observing the heat, or depending on the change of its color, or smelling the difference of its smell, can distinguish the process of the combination.
Furthermore, the proportion of reconciliation is the key. If the proportion is not correct, the compound is not what you want. When using multiple tests to observe the reaction state, remember the amount of raw materials each time, and then obtain the exact ratio.
Or combine in a closed vessel. In this way, impurities can be prevented from mixing, and the gas of the reaction can not be dissipated, which is conducive to the full synthesis. The material of the utensil is also exquisite, or use a clay utensil, because it can slow down the heat dissipation and make the reaction mild; or use a metal utensil, take its heat conduction rate and uniform.
Also, when operating, be cautious. Arsenic is highly toxic, realgar is also toxic, and if you are not careful, you will cause harm to yourself. You must use it in a well-ventilated place, and prepare a cure, just in case.
Although the method of combining these two is not directly described, according to the chemical principles of "Tiangong Kaiwu", according to the raw materials, heat, proportion, utensils and caution, you may get a good method of combining two flavors.
What is the price range of 2-Iodobenzothiophene in the market?
Above the city, the dwellers of the city, the quality of their style, the quality of their style, and the quality of their properties, often change due to the general reasons.
There are many kinds of properties, and the quality is also different. The combination of the two is either a rare material, or a common product. If it is rare, it is matched with a rare one, and its effect is excellent. It is important to the world, and its value is unknown.
As in ancient times, some compatibility can cure chronic diseases. For the rich and those who are thirsty, they will not hesitate to ask for it.
However, if it is often used, the matching price will not be obtained, and the effect will be ordinary, and the price will be low, or the price will be low, or even ten gold ears will be required.
And the price will be high, and it will also affect it. If an epidemic is prevalent, a certain kind of inhabited thing can just be affected by the epidemic, and its price will be high, which is more than usual. On the contrary, if it is urgently needed, it will be high or even low, and it will even fall.
Furthermore, different places have different prices, which can also make the price low. For those who are located in famous mountains, rivers, and places with special water and soil, or because of their mellow nature, they are higher than others.
, they are located above the city, and their price is high, less gold, more gold, or even more. It depends on the general factors such as its price, efficacy, cost, and location.
