Looking at its properties, under normal conditions, 1% 2C2-di (cyanoethyl) naphthalene is mostly white to light yellow crystalline solid, with fine texture and regular appearance. This formation is due to the fixed interaction force between molecules, resulting in an orderly arrangement.
As for the melting point, it is within a specific temperature range. The melting point is the critical temperature at which a substance changes from solid to liquid. The melting point of 1% 2C2-di (cyanoethyl) naphthalene is an important physical characteristic, reflecting the degree of bonding between molecules. This temperature range is a key guideline in many fields such as chemical production and material preparation, and is related to the purity, quality and performance of the product.
When it comes to solubility, 1% 2C2-di (cyanoethyl) naphthalene is soluble in some organic solvents. Organic solvents, such as common aromatic hydrocarbons, halogenated hydrocarbons, etc. In such solvents, the molecules interact with the solvent molecules, or because of similar compatibility, or due to special intermolecular forces, they can be uniformly dispersed to form a uniform and stable system. However, in water, its solubility is very small, because the polarity difference between the molecular structure and water is quite large, and it is difficult for water molecules to break the intermolecular forces to dissolve it.
In addition, the density of 1% 2C2-bis (cyanoethyl) naphthalene is also an important physical property. The density is also the mass of the substance per unit volume. This parameter is of great significance in practical applications, such as the measurement of materials and the control of mixing proportions.

Furthermore, its stability cannot be ignored. Under normal conditions, 1% 2C2-bis (cyanoethyl) naphthalene has a certain chemical stability, and the molecular structure is relatively firm, making it difficult to spontaneously undergo chemical reactions. However, in case of special conditions such as high temperature and strong oxidizing agents, its molecular structure may be affected, triggering a chemical reaction. Therefore, special attention should be paid during storage and use to ensure safety and efficiency.

What are the chemical properties of 1,2-bis (chloromethyl) benzene?
1% 2C2-di (cyanomethyl) benzene is an organic compound with unique properties.
Among this compound, cyanomethyl has a certain reactivity. The nitrile group (-CN) can be converted into a carboxyl group (-COOH) by many reactions, such as hydrolysis reaction. Under the catalysis of acid or base, the nitrile group is hydrolyzed to a carboxyl group (-COOH), so that 1% 2C2-di (cyanomethyl) benzene is converted into a carboxyl-containing compound. This carboxyl compound can be used in organic synthesis to prepare esters, amides, etc.
Furthermore, the α-hydrogen in the cyanomethyl group has a certain acidity. Under the action of strong bases, it is easy to be taken away and carbon negative ions are formed. This negative carbon ion has high activity and can be used as a nucleophilic reagent to undergo nucleophilic substitution or addition reactions with many electrophilic reagents, such as halogenated hydrocarbons, carbonyl compounds, etc. It provides a way to construct carbon-carbon bonds and greatly enriches the strategies of organic synthesis.
1% 2C2 -bis (cyanomethyl) benzene's benzene ring also cannot be ignored. Benzene rings are aromatic and can undergo electrophilic substitution reactions. Because cyanomethyl is an electron-withdrawing group, the electron cloud density of the benzene ring will be reduced, so the electrophilic substitution reaction activity is slightly lower than that of benzene. However, under suitable conditions and catalysts, electrophilic substitution reactions such as halogenation, nitrification, and sulfonation can still occur. The corresponding substituents are introduced into the benzene ring, and various functionalized products are further derived to expand their applications in materials science, pharmaceutical chemistry, and other fields.
In addition, the relative positions of the two cyanomethyl groups (1% 2C2 - position) in the molecule of the compound give it a unique spatial structure, which affects its physical properties and reactivity. Spatial dislocation effects affect intermolecular interactions. In some reactions, it affects the proximity of reagents to the reaction check point, which in turn affects the reaction rate and selectivity.

What are the precautions in the synthesis of 1,2-bis (chloromethyl) benzene?
To prepare 1,2-bis (cyanoethyl) ether, the synthesis process should pay attention to the following things:
The purity of the first raw material, which is the basis for synthesis. Cyanoethanol and concentrated sulfuric acid, both need high purity. Cyanoethanol is impure, or contains impurities that affect the reaction process, resulting in impure products; if concentrated sulfuric acid is of poor quality, the catalytic effect is not good, and the reaction efficiency is also damaged.
Temperature control is the key. In the initial stage of the reaction, the temperature should be maintained at about 50-60 ° C. This temperature can make cyanoethanol interact moderately with concentrated sulfuric acid and initiate a reaction. If the temperature rises too quickly, cyanoethanol is easy to evaporate, or cause local overheating, which triggers side reactions such as carbonization. Wait for the reaction to be stable, and then gradually raise the temperature to 120-130 ° C. This high temperature prompts the etherification reaction to proceed fully. However, the temperature should not be too high, exceeding 140 ° C, the side reactions will surge, and the quality of the product will drop significantly.
Stirring is also indispensable. Good stirring can make the reactants fully contact and distribute heat evenly. If the stirring is uneven, the local reactant concentration is too high or too low, and the temperature is also different. The reaction is difficult to complete, and impurities are prone to occur.
Furthermore, the airtightness of the device should be good. This reaction generates gas. If the device leaks air, not only will the product escape yield be reduced, but the leakage of toxic and harmful gases will also endanger the safety of the experimenter and the environment.
The reaction If the time is too short, the reaction is not completed, and the amount of product is small; if the time is too long, the side reactions will intensify, and the purity of the product will be violated. According to the scale and conditions of the reaction, explore the appropriate reaction time to ensure the balance of yield and purity.
The post-treatment process should not be underestimated. After the reaction, the product contains impurities, which need to be purified by neutralization, water washing, distillation and other steps. Neutralizing sulfuric acid must be accurate. If the acid is not removed or the amount of alkali is too large, the quality of the product will be affected. Washing with water should be sufficient to remove soluble impurities. Control the temperature and pressure during distillation to obtain pure 1,2-bis (cyanoeth
