First, in the field of organic synthesis, it is a key basic raw material. Halogen atoms can be replaced by hydrogen atoms in its molecules by many chemical reactions, such as halogenation reactions, to generate halogenated hydrocarbons. And halogenated hydrocarbons are extremely important in organic synthesis and can be used to prepare alcohols, ethers, nitriles and many other organic compounds. Another example is oxidation reactions. Under appropriate conditions and catalysts, some groups in its molecules can be oxidized and converted into alaldehyde, ketone, carboxylic acid, etc., which lays the foundation for the synthesis of more complex organic compounds.
Second, in the field of fuels, due to their suitable combustion properties, they can be used as components of fuels. It contains hydrocarbons that can release a lot of heat when burned, providing power for various equipment and machinery. Like some specific engine fuel formulations, such alkanes may be added to optimize the combustion characteristics of the fuel, improve combustion efficiency, and thereby enhance the performance of the engine, such as power output, fuel economy, etc.
Third, in terms of solvents, 2% 2C3-diethylpentane is a good organic solvent. Because it is a non-polar or weakly polar molecule, it can dissolve many non-polar or weakly polar organic compounds, such as grease and resin, according to the principle of similar compatibility. In coatings, inks, adhesives and other industries, it is often used as a solvent to dissolve solutes, adjust the viscosity and fluidity of products, and facilitate construction and application. At the same time, in some chemical experiments and industrial production processes, it is also often selected as a reaction medium to allow the reactants to be evenly mixed and promote the smooth progress of the reaction.

2% 2C3 -diethylpentane is an organic compound, and its physical properties are as follows:
Under normal temperature and pressure, it is mostly a colorless and transparent liquid, clear and free of visible impurities. This is the common physical appearance of many alkane compounds.
Smell, with the special smell common to alkanes, light but not strong, not pungent and intolerable smell, but also has its unique smell recognition.
When it comes to boiling point, it is between 120 and 130 ° C. This value fluctuates slightly due to specific experimental conditions and measurement accuracy. The characteristics of boiling point make the substance change from liquid to gaseous state at a specific temperature environment.
As for the melting point, it is roughly around -110 ° C. At this low temperature, the substance condenses into a solid state, and the structure arrangement tends to be regular and tight.
In terms of density, it is smaller than that of water, about 0.75g/cm ³. Therefore, if mixed with water, it will float on the water surface, and the two will be layered due to density differences.
In terms of solubility, it is difficult to dissolve in water, but it is easily soluble in organic solvents such as ether and benzene. This is due to the principle of similarity and compatibility. The organic substance is a non-polar molecule, which is similar in structure to non-polar organic solvents, so it is mutually soluble.

2% 2C3-diethylpentane is an organic compound, and its chemical properties are stable under certain conditions.
Looking at its structure, the carbon chain structure gives this compound a certain stability. The carbon-carbon single bond is relatively stable, and in order to break or react the carbon chain, a high energy supply is required from the outside world. In the conventional environment at room temperature and pressure, 2% 2C3-diethylpentane is usually relatively stable and is not prone to spontaneous chemical reactions.
However, the stability of chemical substances is not absolute. When the environment changes or encounters specific reagents, its stability will also be affected. For example, under high temperature, high pressure or in the presence of a catalyst, 2% 2C3-diethylpentane may participate in the reaction. High temperatures can intensify the thermal movement of molecules, enhance the activity of chemical bonds, and make them more prone to cracking and recombination. In the case of strong oxidizing agents or strong reducing agents, some chemical bonds in 2% 2C3-diethylpentane may be oxidized or reduced, resulting in changes in their structure and properties.
In addition, light may also have an effect on the stability of 2% 2C3-diethylpentane. In some photochemical reactions, light energy is absorbed by molecules, leaving molecules in an excited state, and the molecular activity in the excited state is higher than that in the ground state, thereby triggering chemical reactions.
In summary, the chemical properties of 2% 2C3-diethylpentane are relatively stable under conventional conditions, but when it interacts with reagents in a specific environment, its stability will change, or various chemical reactions will occur.

The synthesis methods of 2% 2C3 -diethylglutaric anhydride are very different. This is based on the text of "Tiangong Kaiwu", and the main method is described as follows.
First, glutaric acid and ethanol are used as raw materials, and an appropriate amount of sulfuric acid is added as a catalyst to carry out the esterification reaction at a suitable temperature. This process requires careful temperature control to maintain the temperature within a certain range to prevent side reactions from occurring. During the reaction, glutaric acid interacts with ethanol and is esterified to form diethyl glutarate. The reaction formula is roughly as follows: glutaric acid + 2 ethyl alcohol + diethyl glutarate + 2 water. This reaction is a reversible reaction, so measures need to be taken to shift the equilibrium to the right to increase the amount of product. Distillation can be used to continuously remove the water generated by the reaction, which prompts the reaction to proceed in the direction of generating diethyl glutarate.
Then, the obtained diethyl glutarate is subjected to a condensation cyclization reaction. Adding a specific basic catalyst, at a higher temperature and under a certain pressure, the ester groups in the molecule of diethyl glutarate interact, condensation cyclization occurs, and a molecule of ethanol is removed to obtain 2% 2C3-diethylglutaric anhydride. This step requires strict reaction conditions, and the temperature, pressure and catalyst dosage need to be precisely controlled to obtain a higher yield product. < Br >
Second, 2% 2C3-diethylglutaric acid can also be used as raw material to directly dehydrate to prepare 2% 2C3-diethylglutaric acid anhydride. Select suitable dehydrating agents, such as acetic anhydride, phosphorus pentoxide, etc. Mix 2% 2C3-diethylglutaric acid with dehydrating agent in a certain proportion, heat and stir. The dehydrating agent reacts with the carboxyl group in glutaric acid to cause it to dehydrate a molecule of water, and then cyclizes to form 2% 2C3-diethylglutaric acid anhydride. After the reaction is completed, the unreacted raw materials, dehydrating agent and by-products are removed through separation and purification, and pure 2% 2C3-diethylglutaric acid anhydride can be obtained. This method is relatively direct, but the choice and dosage of dehydrating agent and the control of reaction conditions have a great impact on the purity and yield of the product, so it is necessary to be cautious.

2% 2C3-diethylpentane, this is an organic compound. In the market price range, it often changes due to purity, supply and demand, market environment and many other factors.
Looking at the current market, if it is 2% 2C3-diethylpentane of ordinary purity, the price per kilogram ranges from tens to hundreds of yuan. If the purity is quite high, it is used in special scientific research or high-end industrial fields, and the price may rise sharply, reaching hundreds of yuan per kilogram.
However, it should be noted that this price is only a rough estimate. The market situation is changing rapidly, and the price of chemical raw materials is often affected by fluctuations in raw material costs, production processes, policies and regulations, and international situations. For example, if the supply of raw materials is in short supply and the production cost rises, the market price will also rise accordingly; or if the production technology is innovated and the production capacity is greatly increased, the price may decline.
Therefore, to know the exact price of 2% 2C3-diethylpentane, you can obtain an accurate figure by consulting chemical product suppliers, distributors, or referring to real-time quotations from professional chemical product trading platforms.
