3-Pyridinemethanol,2-fluoro-(9CI)

The chemical structure of propargyne in Guanfu 9CI is one of the structures of organic compounds. The structure of propargyne contains a one-carbon-carbon triple bond, which is its distinctive feature.
The molecular formula of propargyne is\ (C_3H_4\). In terms of structure, its molecule is composed of three carbon atoms and four hydrogen atoms. Among them, two carbon atoms are connected by carbon-carbon triple bonds. This carbon-carbon triple bond is active and has stronger reactivity than carbon-carbon double bonds. Because its triple bond contains two\ (\ pi\) bonds, the electron cloud density is quite high, which is vulnerable to the attack of electrophilic reagents and triggers various addition reactions.
Furthermore, the hybridization mode of the carbon atom connected to the triple bond is\ (sp\) hybridization, so that the atoms connected to it are arranged in a straight line. The remaining carbon atom is connected to the carbon atom containing the triple bond by a single bond, and the hybridization mode of this carbon atom is\ (sp ^ 3\) hybridization, which presents a tetrahedral spatial configuration. Hydrogen atoms are respectively connected to each carbon atom by covalent single bonds to meet the tetravalent demand of carbon atoms.
The chemical structure of propane gives it unique chemical properties and is often used as an important raw material and intermediate in the field of organic synthesis. Due to the reactivity of carbon-carbon triple bonds, various complex organic compound structures can be constructed by many reactions, such as addition reactions with halogens, hydrogen halides and other electrophilic reagents, which play an important role in the research and industrial production of organic chemistry.

9CI is an ancient artifact. Its material and structure contain the truth of heaven and earth, and its physical properties are very different from ordinary things.
First, it is as solid as a rock and tough as a paddle reed. The texture of 9CI is incomparably hard, and it is rare in the world to damage it in the slightest. In addition to ordinary swords and axes, it is like a mayfly shaking a tree, and it is difficult to leave any traces. However, it is also flexible. When it encounters a huge force impact, it can bend and buffer like soft water, remove the majestic power, and return to its original state when the force is eliminated. It is a wonderful combination of strength and flexibility.
Second, the power of conduction is very strange. In terms of heat and cold conduction, 9CI is not like ordinary things and follows common sense. It can spread extreme cold or heat evenly around the body in an instant, but it can also block conduction under certain circumstances, as if it can control the direction of heat flow. And in terms of energy conduction, it seems to echo the invisible force between heaven and earth, can absorb and gather specific energy, and conducts it to the desired place in a strange way, as if building an exclusive energy channel.
Third, it has the ability to repair itself. If 9CI is accidentally damaged, even if the wound is huge, it can heal itself like a living body. Its healing process is like going back in time, the damaged areas are slowly healed, the lines are gradually restored, and it will be intact in a short time, as if it has never been hurt. These characteristics are amazing.
Fourth, it is light if it is nothing but contains the power of a million. Holding a 9CI, I first felt that it was as light as a feather and effortless. However, once it stimulates its inner power, it is as amazing as opening the world and breaking the earth. It can burst out with the energy of destroying the sky and destroying the earth. The two characteristics of lifting weight and lifting weight are perfectly integrated on 9CI, which is really amazing.

"Tiangong Kaiwu" says: "For every ten catties of money cast, red copper ranks sixth, and red lead (zinc) ranks fourth." The main uses of this lead (9CI) are as follows.
One is used for minting money. In ancient times, when coinage was minted, red lead and red copper were compatible in a certain proportion. As mentioned above, when ten catties of money is minted, red copper is 60% and red lead is 40%. The money minted in this ratio has a suitable texture. It has a certain hardness and is easy to circulate and use for a long time. It also does not lose a certain degree of toughness and is not easy to break or damage. Money is the medium of exchange, which is related to people's livelihood and economy.
Second, in metal smelting and alloy making, red lead has a significant effect. It can be fused with a variety of metals to form alloys with different properties. For example, brass alloys are made with copper, which is harder, shinier, and more resistant to corrosion than pure copper. In the production of various types of utensils, brass is widely used in many aspects of life with these excellent characteristics, from daily household utensils to building decoration components, etc., Ulead can be seen here to improve the performance of alloys.
Third, in the field of weapon manufacturing, Ulead also contributes. When building certain weapons, adding an appropriate amount of Ulead can improve the texture of weapons. Make the edge sharper and the overall strength is improved. In the era of cold weapons, this is essential to enhance the lethality and durability of weapons, which is related to the outcome of wars and national security.
Fourth, in some traditional crafts, lead also plays an important role. For example, in the casting of some metal crafts, adding lead can make the crafts easier to shape complex and exquisite shapes during the molding process, and the surface of the finished product is smoother and flatter, enhancing the artistic value and ornamental value of the crafts.

There are three methods for preparing 9CI-3-dimethyl ether.
One is the Williamson synthesis method. Alcohols and halogenated hydrocarbons are taken as raw materials to combine the two phases. If an appropriate alcohol is used, it first interacts with sodium metal to obtain sodium alcohol, and then mixes with halogenated methyl ether, and reacts in a suitable temperature and solvent. The key to this reaction is that the preparation of alkoxides must be pure, the activity of halogenated hydrocarbons must also be suitable, and the reaction conditions must be precisely controlled, so that a higher yield product can be obtained. The reaction mechanism is nucleophilic substitution. The oxygen anion of the alkoxide salt acts as a nucleophilic agent to attack the carbon atom of the halogenated hydrocarbon, and the halogen atom leaves to form the target product. < Br >
The second is through etherification reaction. Alcohol and methanol are used as the starting materials and carried out under the action of acidic catalysts. Commonly used acidic catalysts such as sulfuric acid can promote the intermolecular dehydration of alcohol and methanol. In this process, the hydroxyl group of the alcohol and the hydroxyl group of the methanol are under acidic conditions, one of the hydroxyl groups is protonated first to enhance its ability to leave, and the oxygen atom of the alcohol or methanol of the other molecule is attacked as a nucleophilic agent, and then a molecule of water is removed to form an ether bond. However, this method needs to pay attention to control the reaction temperature and the amount of catalyst, otherwise side reactions are prone to occur, such as the dehydration of the alcohol to form olefins.
The third is the use of phase transfer catalysis. Using crown ethers as phase transfer catalysts allows the reaction to proceed efficiently in a two-phase system. For example, in a system where the aqueous phase and the organic phase coexist, crown ethers can complex with metal ions to transfer nucleophiles in the aqueous phase to the organic phase and react with halogenated hydrocarbons or other suitable substrates in the organic phase. This method can effectively overcome the problem of low reaction efficiency caused by the difficulty of mass transfer of reactants between different phases in the traditional method, and the reaction conditions are relatively mild. It is also suitable for some more sensitive substrates, which can improve the selectivity and yield of the reaction.

The matter of smelting is related to the people's livelihood of utensils, and there are many things to pay attention to in storage and transportation. As far as Heyang Gold (9CI) is concerned, the first thing to pay attention to when storing is the dryness of the environment. If the cover is in a humid place, the metal is prone to rust, damage its texture, damage its appearance, and damage its value. And the storage place should be sturdy and hidden to prevent thieves from coveting and ensure its safety.
Furthermore, the method of stacking cannot be ignored. When it is sorted and stacked in an orderly manner according to its shape, size, and weight, it is convenient to check and avoid mutual extrusion and collision, resulting in deformation and damage.
As for transportation, the first thing is proper packaging. Use tough materials, such as thick wood, leather, etc., to wrap the gold of the river protection (9CI) to prevent it from being damaged in the bumps of the road. And the choice of the driving route is also very critical. It is advisable to choose a flat and less dangerous path to avoid rough and bumpy places and trouble-prone places to ensure smooth and safe transportation.
When transporting, guards are also indispensable. When sending strong people, they should be strictly guarded to prevent accidents. At the same time, during transportation, regular inspections should be made to check whether the packaging is damaged, whether the transported items are missing or not, and if there is any abnormality, they should be disposed of immediately. In this way, the storage and transportation of the gold of the river sun (9CI) can be properly carried out to keep it intact and make the best use of it.
