The physical properties of 2% 2C3-dimethyl ether imine and N-phenyl are as follows:
This substance is often colorless to light yellow liquid in appearance, and has a certain fluidity in appearance. Smell, there is a special smell, but it is not pungent and intolerable. Its taste is more unique and difficult to describe simply.
When it comes to density, under common conditions, its density is slightly different from that of water. The specific value is subject to accurate measurement. However, it can be roughly determined that its density is smaller than that of water, so if it is co-located with water, it often floats on the water surface.
Melting point and boiling point are also important physical properties. Its melting point is relatively low, and it mostly exists in a liquid state under common ambient temperatures. The boiling point varies slightly due to factors such as environmental pressure. Generally speaking, in a standard atmospheric pressure environment, its boiling point is in a specific temperature range, which needs to be accurately determined by professional instruments.
In terms of solubility of this substance, it shows good solubility in organic solvents. Common organic solvents such as ethanol and ether can be well miscible with it to form a uniform and stable mixed system. However, its solubility in water is quite limited, only slightly soluble in water, and when mixed with water, it is prone to stratification.
In addition, its volatility is also reflected to a certain extent. In an open environment, it will evaporate slowly, causing its mass to decrease over time. Its vapor pressure is also within a certain range, which is closely related to volatility and affects its equilibrium between the gas and liquid phases.

What are the chemical properties of 2% 2C3 - dimethyl ether sulfoxide, N-amino group? This is a question in organic chemistry to explore the properties of specific compounds.
2% 2C3 - dimethyl ether sulfoxide, N-amino group, has a certain polarity. Because its molecular structure contains polar groups such as sulfur and oxygen double bonds and amino groups, it can have good solubility in polar solvents. With similar compatibility, polar compounds are easily soluble in polar solvents, and the polarity of this compound makes it soluble in polar solvents such as water and alcohols.
Furthermore, its amino groups have certain alkalinity. Amino-nitrogen atoms have lone pairs of electrons and can accept protons, so they can react with acids to form salts. In case of inorganic acids such as hydrochloric acid, amino groups can combine with hydrogen ions to form corresponding ammonium salts.
And the sulfur-oxygen double bonds in its molecules also have certain chemical activity. It can participate in some redox reactions. Sulfur atoms are in a higher oxidation state, or can be reduced under appropriate conditions, changing their chemical structure and properties.
At the same time, the carbon chain structure of the compound also affects its properties. The length and branching of the carbon chain can affect its physical properties such as melting point, boiling point, etc. The relatively long carbon chain may increase the melting point and boiling point of the compound, and also affect its solubility. Because the carbon chain is a non-polar part, too long will reduce its solubility in polar solvents.
In addition, the compound may participate in nucleophilic substitution reactions. The lone pair electron of the amino group can be used as a nucleophilic reagent to attack suitable electrophilic reagents, resulting in substitution reactions to generate new organic compounds, which may have important applications in the field of organic synthesis.

To prepare a 2,3-dimethyl ether imide, N-benzyl compound, the method is as follows:
First, use a suitable solvent, such as dichloromethane, tetrahydrofuran, etc., to create a reaction environment. Take an appropriate amount of 2,3-dicarbonyl compound, place it in it, and stir well. This dicarbonyl compound is a key starting material in the reaction system, and its structural characteristics have a great influence on the subsequent reaction process and product configuration.
Take benzylamine for a second time, and slowly add it dropwise to the above solution containing 2,3-dicarbonyl compound according to a certain stoichiometric ratio. The amount of benzylamine needs to be precisely controlled. Too much or too little can cause the reaction yield to be low or by-products to be formed. The dropwise addition process should be slow, and at the same time pay close attention to the temperature change of the reaction system. Cold water bath or other temperature control means can be used to maintain the temperature within a suitable range, generally between 0 and 30 ° C, to prevent the reaction from being too violent and out of control.
After the dropwise addition is completed, add an appropriate amount of dehydrating agent, such as molecular sieve or anhydrous magnesium sulfate. The function of the dehydrating agent is to remove the water generated during the reaction process, promote the reaction equilibrium to move in the direction of the product, and improve the product yield.
Then, stir the reaction mixture at room temperature or under moderate heating conditions. The heating temperature should not be too high, otherwise it is easy to cause side reactions. During this period, by thin layer chromatography (TLC) or other analytical methods, the reaction progress should be monitored regularly until the raw material point is basically eliminated, indicating that the < Br > After the reaction is completed, the reaction solution is post-treated. First, the product is extracted with a suitable organic solvent, such as ethyl acetate, etc., to transfer the product to the organic phase. After liquid separation, the organic phase is washed with water and saturated salt water to remove impurities. Then the organic phase is dried with anhydrous sodium sulfate, the desiccant is filtered off, and the organic solvent is distilled under reduced pressure to remove the organic solvent to obtain a crude product.
Finally, the crude product is purified by column chromatography or recrystallization to obtain a pure 2,3-dimethyl ether imine, N-benzyl product. During column chromatography, appropriate silica gel and eluent are selected, and the proportion of eluent is adjusted according to the polarity of the product to achieve the best separation effect; for recrystallization, a suitable solvent needs to be selected to make the solubility of the product change significantly with temperature, thereby precipitating high-purity crystals.

In today's world, business conditions are unpredictable, and the ups and downs of prices are influenced by many factors. The prices of 2,3-tetraethyl butyrate and N-benzyl in the market are not static.
The supply and demand of the city is the key to the price. If the market needs 2,3-tetraethyl butyrate and N-benzyl, and the supply is limited, the price may rise; conversely, if the supply exceeds the demand, the price may drop.
Furthermore, the price of raw materials also has a great impact. 2,3 - To the production of ethyl butyrate and N-benzyl, specific raw materials are required. If the price of raw materials increases, the production cost increases, and the market price may also increase; if the price of raw materials decreases, the price of the product may also decrease accordingly.
Process and technology should not be ignored. If the new process technology can increase production efficiency and reduce costs, the product may be more competitive at the market price, or decrease.
In addition, the stability of the current situation and the orientation of policies are all related to prices. Political stability, policy support, conducive to production, prices may be stable; conversely, turbulent times, unfavorable policies, prices may fluctuate.
Therefore, in order to know the current market price of 2,3-tetraethyl butyrate and N-benzyl, it is necessary to gather extensive business information, observe changes in supply and demand, movements in raw material prices, and new processes, and consider the current situation and policies, and comprehensively consider, in order to obtain a more accurate price. However, I have not yet known the specific market conditions, so it is difficult to tell you the exact price.
