This compound has a certain melting and boiling point. Its melting point and boiling point are determined by intermolecular forces, and the molecular structure and relative molecular weight are also affected. When the intermolecular forces are strong, the melting and boiling point is higher; otherwise, it is lower.
In terms of solubility, follow the principle of similar miscibility. If this substance contains polar groups, it is soluble or better in polar solvents; if the non-polar part accounts for a large proportion, it is more soluble in non-polar solvents. If it contains polar groups such as hydroxyl groups, it may have a certain solubility in water; if the alkyl chain is longer, the non-polar enhancement, or better solubility in organic solvents such as petroleum ethers.
Density is related to its floating and sinking relationship with other substances. The density of the compound depends on the type, quantity and molecular stacking mode of its constituent atoms. The relative molecular mass is large and the molecular stacking is tight, and the density is large or large; the reverse is small. Compared with water, if the density is greater than that of water, it sinks in water; if it is less than water, it floats on the water surface.
Volatility is related to the intermolecular force. The intermolecular force is small and the volatility is strong. It is easier to transition from liquid to gaseous and escape at room temperature; if the force is large, the volatility is weak. If the intermolecular force is weak, the compound may evaporate rapidly in an open environment.
Stability is also an important physical property. Under certain conditions, its ability to maintain its chemical structure is affected by chemical bond energy and spatial structure. The chemical bond energy is high, the spatial structure is stable, the material is stable, and it is not easy to chemically react; otherwise, it is easy to decompose or react with other substances.
All the above physical properties need to be considered in detail when applying this compound in chemical, pharmaceutical and other fields.

To prepare 2-triethyl-5-carboxyl group, there are three methods, which are described in detail as follows.
One is the hydrolysis of halogenated hydrocarbons. First, a suitable halogenated hydrocarbon is heated with an aqueous solution of a strong base, and the halogen atom is replaced by a hydroxyl group to obtain an alcohol. After oxidation, the alcohol can be converted into the corresponding carboxylic acid. For example, a halogenated hydrocarbon containing the target substituent is heated in an aqueous solution of sodium hydroxide, the halogen atom leaves, and the hydroxyl group is connected to generate an alcohol. Then a strong oxidant, such as an acidic potassium dichromate solution, oxidizes the alcohol to a carboxylic acid. This process requires attention to the control of reaction conditions. If the temperature is too high or the oxidant is too excessive, it may cause excessive oxidation. < Br >
The second is the hydrolysis of nitriles. The halogenated hydrocarbons containing the target group are selected to react with sodium cyanide to form nitrile compounds. Nitriles are hydrolyzed under acidic or alkaline conditions to obtain carboxylic acids. In this reaction, the reaction of halogenated hydrocarbons and sodium cyanide needs to be carried out in a suitable solvent to ensure a smooth reaction. In the hydrolysis step, the acidic hydrolysis conditions are mild, but it takes a long time; the alkaline hydrolysis speed is fast, but subsequent acidification is required to obtain carboxylic acids.
The third is the Grignard reagent method. First, a halogenated hydrocarbon containing the target substituent is prepared, which reacts with magnesium in anhydrous ethyl ether to form a Grignard reagent. Grignard reagent reacts with carbon dioxide This method requires a strict anhydrous and anaerobic environment, because Grignard's reagent will react with water and oxygen and fail. During the reaction, the amount of carbon dioxide and the reaction temperature also need to be precisely controlled to obtain a higher yield product.
These three methods have their own advantages and disadvantages. In practical application, when considering the availability of raw materials, the difficulty of reaction conditions, and the purity of the product, the optimal method is selected to prepare 2-triethylmethyl-5-to-its carboxyl group.

What is the price of di-triethylmethyl-5-pentenoic acid in the market today? This is a matter related to the price of goods and the market situation. To know its price, when looking at the supply and demand of the market, the amount of production, the change of time and other factors.
The supply and demand of the city, if there are many people who want this thing, and there are few people who supply it, the price will increase; on the contrary, if the demand is thin, and the supply is large, the price will be reduced. The amount of production is also crucial. If the origin is wide, the output is abundant, and the transportation is smooth, the market's goods will be sufficient, and the price may be stable but low; if the production is narrow, the production is difficult, and the transportation is difficult, the price will be low.
The change from time to time can also affect its price. The age is different, and those who use this product may increase or decrease. If at a certain time, this product is in urgent need in various industries, the price will jump; when it is used slowly, the price will also gradually flatten.
However, I have not been involved in the market of this product, so it is difficult to determine the current price. If you want to get an accurate price, you can consult a pharmaceutical company, a merchant, or visit a chemical market, observe the price of the transaction there, and ask the expert to get the details. It is necessary to personally explore the market situation, visit the relevant people, and measure the changes in its supply and demand, production and transportation in time, so as to know the price of di-triethylmethyl-5-pentenoic acid in the market.

This medicine needs to be sealed in a porcelain bottle and placed in a cool and dry place that is out of reach of children. Because of its delicate nature, it is afraid of the tide and the sun. The tide is perishable, and the sun is easy to disperse. Those who seal it, prevent it from mixing with the outside world's foul gas, and keep its medicinal power pure. A cool and dry place can protect its medicinal properties from being stable, and will not lose its effect due to changes in temperature and humidity. As for children, they cannot be touched, so although the medicine has wonders, it is strong in nature. Children accidentally eat it, and they are afraid of accidental changes, endangering their lives. Therefore, by following this method of storage, the 2-%E4%B8%89%E6%B0%9F%E7%94%B2%E5%9F%BA-5-%E5%90%A1%E5%95%B6%E7%BE%A7%E9%85%B8%E7%9A%84%E8%8D%AF%E5%8A%9B can be kept long and prosperous, and it can be effective when used.
