"Tiangong Kaiwu" has a saying: "The silk, hemp, fur and brown in the world have quality, and the special face and color can still be used. I don't believe it if I say that the creation of things is not laborious." The husband 2%2C3%2C5-%E4%B8%89%E6%BA%B4%E5%90%A1%E5%95%B6, also the ingenuity of creation. It is very important to the way of engineering and technology.
In the manufacturing industry, this three-way valve can be used for the flow of fluids in and out and the amount of flow. For example, when making a device, if you want to control the flow of water, or adjust the strength of the air flow, it depends on this valve. Taking the water device as an example, if you want to make the water evenly injected into the device, it will not flood or dry up, 2%2C3%2C5-%E4%B8%89%E6%BA%B4%E5%90%A1%E5%95%B6 can be opened and closed at the right time, so that the flow of water is appropriate.
Furthermore, in the chemical industry, the valve also plays a significant role in the transportation and reaction process of materials. Different chemical substances can be precisely prepared by the valve according to the needs of the manufacturing process to form their chemical reactions and obtain the desired products. If this valve is missing, the proportion of materials is improper, the reaction may not be successful, or it may cause danger.
In the HVAC system, the 2%2C3%2C5-%E4%B8%89%E6%BA%B4%E5%90%A1%E5%95%B6 can regulate the distribution of hot and cold air. In summer, the air conditioner can flow freely in the room to relieve heat; in winter, the heat is guided into the room to prevent severe cold. And according to the size of the room and the number of people, the air flow can be adjusted to make the room temperature suitable for people.
In short, although 2%2C3%2C5-%E4%B8%89%E6%BA%B4%E5%90%A1%E5%95%B6 is small, it is indispensable in many aspects of industrial manufacturing, scientific research, and daily use.

2% 2C3% 2C5-trialkylebenzene is an organic compound with unique physical properties. It is colorless to light yellow liquid and is stable at room temperature and pressure. The melting boiling point of this substance is closely related to the intermolecular force and molecular weight. The melting point is about -20 ° C, and the boiling point is between 200 ° C and 220 ° C. Due to the conjugated triple bond structure of the molecule, its density is slightly higher than that of water, about 1.1 - 1.2 g/cm ³.
2% 2C3% 2C5-trialkylebenzene is insoluble in water because of the strong polarity of water molecules, and the substance is a non-polar molecule, which is difficult to dissolve in water according to the principle of "similar miscibility". However, it is soluble in common organic solvents, such as ethanol, ether, dichloromethane, etc. The solubility in these solvents varies depending on the properties of the solvent and temperature.
Its volatility is relatively low. Due to the strong force between molecules, more energy is required for molecules to break away from the liquid surface. Stability in air is acceptable, but in case of open flames and hot topics, it may cause combustion explosions because of its flammability. At the same time, the substance has certain toxicity and potential harm to human health. Protective measures need to be taken during operation.
2% 2C3% 2C5-triacetylbenzene is an important intermediate in the field of organic synthesis. With its special structure, many organic materials with special properties can be synthesized, such as photoelectric materials, functional polymers, etc. In the field of materials science, it can be introduced into the polymer backbone or side chain through a specific chemical reaction, endowing the material with unique electrical and optical properties, opening up a broad space for the research and development of new materials.

2% 2C3% 2C5-trialkynyl, its chemical properties are uncertain. This is a question of the chemical field. If you want to clarify it, let me explain it.
2,3,5-trialkynyl, its chemical properties are uncertain. The alkynyl group, which is not the chemical base of the chemical group, contains carbon-carbon triglycerides. This triglyceride has high energy, making it phase-reactive.
Because there are π in the carbon-carbon triglyceride, and π are exposed to the outside, it is vulnerable to attack by. Often, the reaction of alkynyl groups, such as the addition of alkynyl groups, isotopes, isotopes, etc. can be added to the alkynyl group, so that the trialkynyl group can be cracked to form a new reaction.
There is also a reaction reaction. Under the appropriate catalysis, the alkynyl group can be added, and the alkylene group can be formed first, and the alkyl group can be formed. This shows the reaction activity of the alkynyl group.
In the 2,3,5-trialkynyl group, the polyalkynyl group does not exist, which increases its reaction activity. Different alkynyl groups or mutual shadows make the molecular integration more active. Therefore, the chemical properties of 2,3,5-trialkynyl groups are determined, and they are easy to be reversed and biochemical.

** First, the method of combined refining of aluminium, saltpeter and sulfur **
Take a number of aluminium, its dryness is strong, and it can melt all things. Then prepare saltpeter, saltpeter, when heated, it will be sent, which is the key to change. And take sulfur, sulfur is flammable, which can add force to the synthesis. Put these three in a crucible according to the appropriate proportion. First bake slowly over low heat, so that all things are melted, see its color change, gas out, and then calcined with fierce fire. After it is fully reacted and cooled, 2,3,5-tricarbonne can be obtained. This process needs to be handled with caution, because aluminium, saltpeter, and sulfur are all strong, and a little carelessness will cause trouble.
** Second, the method of co-heating charcoal and metal salts **
Select high-quality charcoal, which is pure and has a high carbon content. Prepare metal salts, such as copper salts, iron salts, etc. Grind the charcoal and mix it with the metal salts in a certain proportion. Put it in a special furnace and blast it with a bellows to make the furnace temperature gradually higher. The combustion of charcoal produces high temperature, which prompts the metal salts to chemically react. Under the action of high temperature, the metal ions in the metal salt interact with the carbon element, and through a series of complex changes, it may form 2,3,5-tri-carbyne. This process requires attention to furnace temperature control. If the temperature is too high or too low, it is not conducive to product formation.
** Third, use the method of cracking vegetable oils **
to select suitable vegetable oils, such as flax oil, tung oil, etc. The oil is placed in a closed container and heated with special equipment. As the temperature rises, the oil molecules begin to crack. When a specific temperature is reached, the carbon chains in the oil molecules break and recombine. By precisely controlling the temperature and reaction time, 2,3,5-tricarbonne appears in the cracking products. However, this process needs to be carefully grasped. Due to the complex composition of vegetable oils, the reaction is prone to impurities, which affect the purity of the product.

There are two, three, three and five prism today, and the price range on the market varies depending on its material, process, size, etc. If the material is fine, the grinding is meticulous, and the size is moderate, the price may be slightly higher; if the material is ordinary and the process is normal, the price may be slightly lower.
Generally speaking, the price of an ordinary prism on the market may be between tens and hundreds of dollars. If it is refined, the material is high, and it has special purposes, the price may reach more than a thousand dollars.
However, the price on the market fluctuates from time to time, and the market conditions vary from place to place. Therefore, if you want to know the exact price, you must go to the market and consult the merchants before you can get it. There is also a way to shop online, and you can also get the approximate price. However, when purchasing, you should also pay attention to its quality and after-sales services to avoid any losses.
