6-(trifluoromethyl)pyridine-3-carboxaldehyde

(Trimethylmethyl) To the three of them, the main user is the one who uses it, because the meat is delicious and has a nourishing effect. Its meat is rich in protein and multiple vitamins, such as glutamate, glutamate, etc., which can increase the cost and benefit the weak people. Often eating armor can nourish and benefit the blood, so that the blood is full and the body is healthy. In ancient times, the official and the famous people often used it as a delicacy, which was used for banquets and guests to show their wealth and respect, and also used it for their own nourishment and protection.
Furthermore, the armor of the armor is also known as the material. It has the effect of dispersing and calming the liver. In the family, in case of hepatic hyperactivity, dizziness, or sputum and other diseases, the armor is often taken, and the nail is ground and ground. In addition, there is also an auspicious meaning in the culture. Its life is not good, and the elephant is not healthy. In some important days or ceremonies, people also like to use armor to enter the body, praying for the prosperity of the family and the life of the family. Therefore, (trimethyl) to the three of them, or to eat for the body, or to take armor for use, or because of cultural implications, the use is wide and important.

To make 6- (triethyl) heptyl-3-ene, the following methods can be used:
First, based on the elimination reaction of halogenated hydrocarbons. Select an appropriate halogenated hydrocarbon, such as 6-halo- (triethyl) heptyl-3-alkane, in a strong alkali alcohol solution, and heat it to promote the digestion of hydrogen halides. For bases, such as an alcohol solution of potassium hydroxide. This reaction process is an E1 or E2 mechanism. The halogen atom leaves, and the hydrogen on the adjacent carbon is taken away by the base, thus forming a carbon-carbon double bond. The advantage is that the reaction conditions are easier to control and the yield is acceptable; if there is a lack of halogenated hydrocarbons, the preparation may be slightly cumbersome, and side reactions may occur, such as rearrangement reactions.
Second, through alcohol dehydration reaction. Prepare 6- (triethylmethyl) heptyl-3 - alcohol, and use concentrated sulfuric acid or alumina as a catalyst to heat dehydrate. When catalyzed by concentrated sulfuric acid, the temperature should be controlled within an appropriate range, otherwise it is prone to side reactions such as carbonization and etherification. This way, the raw material alcohol is easier to obtain, and the reaction principle is clear; however, concentrated sulfuric acid is highly corrosive, requires high equipment, and the post-processing is complicated.
Third, the alkyne reduction method is used. First prepare the corresponding alkynes, such as 6- (triethylmethyl) heptyl-3-alkynes, and catalyze hydrogenation with lindela catalyst (Pd-CaCO, plus a small amount of quinoline and other inhibitors) to obtain the target olefin. This method has good selectivity and can obtain olefins of specific configurations; however, the preparation of alkynes may require multiple steps, and lindela catalysts also need to be properly prepared and stored.
Fourth, use Wittig reaction. Aldides or ketones react with phosphorus ylide reagents to form carbon-carbon double bonds. First synthesize aldides or ketones containing (triethylmethyl), and react with suitable phosphorus ylide reagents in appropriate solvents (such as ether, etc.). The reaction conditions are mild and the double bond position selectivity is good; however, the preparation of Yelide reagent is more complex and the cost may be higher.

(Trimethylmethyl) alkyne and trimethylsilicon have similar physical properties. Its color is transparent, and if it is a liquid, it can flow freely under normal conditions.

Its melting and boiling speed is low, so it can be cured in general conditions; the boiling speed is also not very high, and it is easy to melt when the temperature is increased. This property makes it a good reaction medium in the process of diversification, because it is easy to control the reaction, or the liquid phase is reversed, or the addition of the liquid phase is mixed, which is convenient for chemical applications.
Furthermore, its density is low in water, and if the water is co-located, it can float on the water surface. This property also helps to improve the distribution. And its solubility is not special, and it can be dissolved in many soluble substances, such as ether and other substances, but the solubility in water is not very high, so it is convenient to use its poor solubility to extract and separate compounds.
Its solubility is also low, and it is open in the air, and it is easy to disperse in a short time. This property is due to some combination or inconvenience. If you want to preserve this material, you need to be dense and properly; however, in other synthesis steps, you can use its solubility to remove many substances in the reaction system.
In addition, (trimethyl) alkyne trimethyl silicon has a certain degree of solubility, and it is not easy to react to the common material under normal conditions. However, in the case of acid, chemical or specific catalysts, it can also lead to chemical reactions, which are generally synthesized, thus laying the foundation for its important uses in the chemical industry.

In today's world, the world is bustling, all for profit; the world is bustling, all for profit. Business is vertical and horizontal, and price changes are related to all kinds of things. If you ask about the market prices of trienomethyl and trimethylsilicon, it is difficult to sum it up.
Changes in market prices are unpredictable and subject to many factors. First, the balance between supply and demand. If there are many people who want this thing, and there are few people who supply it, the price will rise; if the supply exceeds the demand, the price will be depressed. Second, the price of raw materials. If the price of the raw materials required for its preparation is high, the price of the finished product will also be high; if the price of the raw materials drops, the price of the finished product may also drop. Third, the rules of government. Where the decree is concerned, it is related to production, trade, or awards or restrictions, all of which affect the price. Fourth, the competition in the market. Competition among the same industry, either for profit, or to occupy the market, there are many means, and it also affects the price.
Therefore, if you want to know the real-time price of trienyl methyl and trimethylsilicon, you need to constantly observe changes in the market, analyze the situation of supply and demand, know the price of raw materials, understand the regulations of the government, and observe the competition of the same industry. In this way, you can get a general idea. However, the market is not constant, although those who are good at observing it, it is difficult to fully understand its changes. Only by constantly thinking and observing can they respond.

Trimethylamine is stored in the container, and the trimethylamine is stored in the container. Pay attention to the situation.
The first heavy density is stored. Trimethylamine is not active, and it is easy to escape and dissipate in the air. If the container is not stored in the container, it will not cause material loss, and its pungent smell will pollute the environment, and it will also lead to poisoning. Therefore, the container must be sealed with a sealing device, and its tightness should be checked regularly to prevent leakage.
The second word is taken from the environment. Trimethylamine should not be high, and the source of fire should be high, and it should be well-connected. Because trimethylamine is flammable, it is at risk of explosion in case of open fire and high temperature. All fire sources and sources should be equipped with fire fighting equipment. And good communication can reduce the degree of trimethylamine in the air, and reduce the risk.
It has also been studied. It meets the requirements of dangerous products, and there are relevant warnings. Be careful and careful to prevent package breakage. On the way, the company will pay close attention to the people in the warehouse to avoid package leakage caused by emergency and severe bumps. If the road is densely populated or sensitive, it is even more difficult to meet the road and avoid peak periods.
Furthermore, human prevention should not be ignored. Inventory management or operation, all personnel should be equipped with anti-trimethylamine equipment, such as gas masks, anti-trimethylamine gloves, etc., to prevent direct connection of people to protect people's safety and health.
Therefore, the storage of trimethylamine should be paid attention to in terms of density, environment, environment and prevention in order to ensure safety.
