As for the boiling point, it is about 280-290 ° C. The boiling point is also the critical temperature at which a substance changes from liquid to gaseous state. This boiling point indicates that 2% 2C6-diethyl azelaic acid needs to be at a relatively high temperature to begin boiling and vaporizing. This characteristic makes it in a high temperature environment, or can maintain the stability of the liquid state, and is used in some processes or systems that need to withstand a certain temperature.
Its melting point is very low, about -40 ° C. The low melting point makes it easy for 2% 2C6-diethyl azelaic acid to maintain a liquid state at room temperature, but it is not easy to solidify into a solid state. This property facilitates its practical application, such as as as a solvent or participating in certain liquid-phase reactions, because it does not require additional heating to maintain the liquid state, saves energy and is easy to operate.
In terms of density, it is about 0.96 - 0.98g/cm ³. The density reflects the mass per unit volume of the substance.

2% 2C6-diethyl diacetate, which is an important compound in organic synthesis. There are several common methods for its synthesis:
First, 2,6-dimethylphenol is used as the starting material. First, 2,6-dimethylphenol is reacted with halogenated ethyl acetate under alkaline conditions. The base can be selected from potassium carbonate, etc., in a suitable solvent, such as N, N-dimethylformamide (DMF), and the nucleophilic substitution reaction occurs. The oxygen atom of the phenolic hydroxyl group acts as a nucleophilic reagent to attack the carbon atom attached to the halogen atom of the halogenated ethyl acetate, and the halogen atom leaves to form an ether bond, resulting in 2,6-dimethylphenoxy ethyl acetate. Then, through a series of reactions, such as oxidation, the methyl group on the benzene ring is suitably modified to achieve the synthesis of the target product 2,6-diethyl dioxate.
Second, m-xylene is used as the starting material. First, the alkylation reaction of m-xylene is used to introduce a suitable substituent. For example, under the catalyst of Lewis acid catalyst, such as anhydrous aluminum trichloride, the halogenated alkane is reacted in a suitable solvent to connect the alkyl group to the benzene ring. After that, the side chain on the benzene ring is oxidized to a carboxyl group through an oxidation reaction. This oxidation process can choose a strong oxidizing agent, such as potassium permanganate. After 2,6-dicarboxybenzene is obtained, it is esterified with ethanol under the catalysis of concentrated sulfuric acid. Concentrated sulfuric acid plays a dual role of catalysis and water absorption, which prompts the reaction to proceed in the direction of ester formation, and finally synthesizes 2,6-diethyl dicarboxylate.
Third, benzene is used as the starting material. First, a multi-step substitution reaction is carried out on benzene, and methyl and carboxyethyl ester groups are gradually introduced. For example, methyl is first introduced through Fu-g alkylation reaction, and then the desired substituent structure is gradually constructed through other reactions, and finally 2,6-diethyl dicarboxylate is synthesized. This route step is relatively complicated, and the reaction conditions need to be precisely controlled to ensure the selectivity and yield of each step of the reaction.
The above synthesis methods have their own advantages and disadvantages. In practical applications, the most suitable synthesis path should be selected based on the availability of raw materials, the difficulty of reaction conditions, and the cost.

2% 2C6 - Diethyl diacetate in storage and transportation, many matters need to be paid attention to. This is a chemical substance with special properties, related to safety and quality, and should not be ignored.
When storing, choose the first environment. It should be placed in a cool, dry and well-ventilated place. Because it is afraid of moisture and humid air is easy to deteriorate, the humidity in the warehouse must be strictly controlled, generally between 40% and 60%. And the temperature should not be too high. High temperature can easily promote its chemical reaction and cause danger. It is appropriate to use 5-25 ° C.
Furthermore, the storage place should be kept away from fire, heat and oxidants. This diethyl diacid is flammable. In case of open flames and hot topics, it can cause combustion, encounter with oxidants, or react violently, with unimaginable consequences. At the same time, storage containers should also be carefully selected. Corrosion-resistant materials, such as stainless steel or specific plastic materials, should be selected to prevent the container from reacting with substances and affecting quality.
When transporting, the packaging must be strong and tight. Use special chemical transportation packaging to ensure that there is no risk of leakage. Transportation vehicles must also meet safety standards, be equipped with fire extinguisher materials and leakage emergency treatment equipment. During transportation, avoid bumps and vibrations to prevent packaging damage. And the route should avoid sensitive areas such as water sources and densely populated areas to prevent accidental leakage from causing serious pollution and harm. When loading and unloading, the operator needs to wear professional protective equipment, light loading and light unloading, and it is strictly forbidden to drop and drag to ensure the operation specifications and ensure the safety of personnel and material integrity. In this way, 2% 2C6-diethyl diacetate is safe during storage and transportation.
