Its color is light yellow or light brown, and it looks warm and moist, like uncut jade.
Its shape is often flaky, which can be curled and continuous, and it is flat like a ruler. Touch it, it feels delicate, like the smoothness of a baby's skin, but it is also tough and not easy to fold. Under the sun, it is slightly shiny, just like sparkling waves, shining. < Br >
In the air, it can be stored for a long time, does not rot or moth, and does not change its quality over time, which seems to have a constant nature. Its sound is also different, with a light flick of the finger, making a crisp sound, like beads falling on a jade plate, with a lingering sound. Its taste is light and slightly refreshing, and it smells fresh, imitating the early germination of grass and trees in Foshan forests. And this material has good insulation, and the current cannot pass through, so it can be used for protection. And because of its flexibility and firmness, it can flex and stretch, so it is often a good material in the production of many utensils, and can be shaped by adjuvants to increase its durability.

2-%E4%B8%89%E6%B0%9F%E7%94%B2%E5%9F%BA%E5%90%A1%E5%95%B6, the transformation properties are very different, and it can be studied. This substance has several characteristics, and it often shows a wonderful state in various reactions.
Looking at its physical properties, it is often a colorless liquid, with a faint fragrance when smelled, and a smooth touch. Its boiling point and melting point have specific values, which can be used as evidence when separating and purifying. And its density is slightly lighter than that of water. If placed in water, it often floats on it, and the boundaries are clear, such as Jingwei.
As for the chemical properties, it is very active. When encountering strong oxygen agents, it is easy to oxidize. In its molecular structure, specific bond energies and bond angles make it show a unique tendency in the reaction. If it encounters with acids, it can be substituted, and the alkyl group can be replaced by other groups, resulting in new substances, and the properties will also change.
In addition, it also responds to bases, although it is not as violent as acid, it can also change in a suitable environment. And in the field of organic synthesis, 2-%E4%B8%89%E6%B0%9F%E7%94%B2%E5%9F%BA%E5%90%A1%E5%95%B6 is often an essential material, and it can be used as a reaction for specific groups, so that the product has different properties.
In the state of light or heat, the 2-%E4%B8%89%E6%B0%9F%E7%94%B2%E5%9F%BA%E5%90%A1%E5%95%B6 is also unstable, and it can be decomposed or rearranged. The molecular structure is broken and then established, and the new quality is born. In short, the 2-%E4%B8%89%E6%B0%9F%E7%94%B2%E5%9F%BA%E5%90%A1%E5%95%B6 of chemistry, in the field of organic chemistry, such as the star shining, in all kinds of reactions and synthesis, are of extraordinary significance, can be the cornerstone of the chemical industry, medicine and other industries, help all kinds of new things come out, benefit the world.

To prepare dichloromethylpyridine, there are various methods.
First, pyridine is used as the starting material and is halogenated. First, pyridine is reacted with an appropriate halogenating agent, such as chlorine, at a suitable temperature, pressure and catalyst. This process requires careful temperature control, because the reaction is prone to intense. First, one chloropyridine is obtained, and then, after re-halogenation, the chlorine atom gradually replaces the hydrogen atom on the pyridine ring, and finally two-trichloromethylpyridine is obtained. However, in this way, the reaction step is slightly complicated, and the selectivity of the halogenation position also needs to be refined, otherwise impurities will be easily generated.
Second, pyridine derivatives containing specific substituents are used as raw materials. For example, a pyridine compound with a substituent that can be converted into trichloromethyl is selected, and the substituent is converted into trichloromethyl through a specific chemical reaction. This method may simplify the steps and improve the purity of the product. However, it is difficult to obtain the raw materials, and the conditions of the conversion reaction need to be carefully investigated.
Third, through a new strategy of organic synthesis. For example, the reaction path catalyzed by transition metals is used, and the unique activity and selectivity of metal catalysts are used to make the reaction more targeted. With a suitable metal catalyst and a specific ligand, the reactants are combined in the expected way to form dichloromethylpyridine. Although this approach is innovative, the choice and recycling of catalysts, as well as cost considerations, are all problems that need to be faced in practical applications.
All these methods have their own advantages and disadvantages, and they need to be carefully selected according to actual conditions, such as the availability of raw materials, cost, and requirements for product purity.

In today's world, the business market is complex and prices are volatile. It is not easy to determine the price range of 2-triethylamino in the market. However, according to various ancient books and trading prices in previous years, it can be roughly deduced.
Check past business records, the price of 2-triethylamino often varies according to the quality and the supply and demand of the market. If the quality is high and the market is prosperous, the price may be high; if the quality is flat and the supply exceeds the demand, the price will tend to drop.
In the past, when the market was prosperous, the price of high-quality 2-triethylamino could reach more than a hundred gold per amount; but when the market was tired, when the supply and demand were limited, it may drop to tens of gold. In general, its price often fluctuates between tens of gold and hundreds of gold.
However, this is only an example of past years. In today's city, the situation is changing, new technologies are emerging, production methods are different, and the trend of supply and demand has also changed. In addition to all kinds of taxes, freight, etc., the price can be greatly changed.
Although the price of the past can be used as a reference, if you want to know the exact price of 2-triethylamino at present, you still need to visit the market in person, consult merchants, and observe the reality of supply and demand there, so that you can get a definite number to meet the needs of business.
