2% 2C4-dimethyl-1-diethylamino naphthalene, this is an organic compound. Its physical properties are as follows:
Viewed at room temperature, it is mostly solid, or crystalline powder, white or nearly white, fine and uniform. Its shape is easy to access and operate, and it has advantages in many experiments and industrial processes.
Smell, it has a specific organic smell, but it is not pungent and unpleasant, but relatively mild. However, in a poorly ventilated environment for a long time, it may still stimulate the sense of smell, so pay attention to ventilation when exposed.
In terms of melting point and boiling point, the melting point has its specific value, which is the critical temperature of the substance from solid to liquid state, which is determined by the intermolecular force and structural characteristics; the boiling point is the temperature of liquid to gas state. A higher boiling point indicates that the intermolecular attractive force is strong, and more energy is required to vaporize it. This property is of great significance when separating and purifying the substance, and can be separated by distillation and other means depending on the boiling point difference.
In terms of solubility, it has a certain solubility in common organic solvents such as ethanol and ether. Due to the fact that its molecular structure contains organophilic groups, it can interact with organic solvent molecules by means of van der Waals force, hydrogen bonds, etc., to help them dissolve. However, its solubility in water is low, because the overall hydrophobicity of the molecule is strong, and water is a polar solvent. It has weak interaction with the molecule of the substance and is difficult to miscible. This difference in solubility can be used in extraction operations to separate and purify the substance from the mixture.
Density is also an important physical property, and the relative density may be different from that of water, which is crucial when it comes to liquid-liquid separation or determining its location in a specific system.

2% 2C4-dimethyl-1-diethylamino naphthalene, this physical property is not solid. Its molecular structure contains dimethyl and diethylamino groups, and this structural feature makes it have unique physical and chemical properties.
Looking at its physical properties, it may be in a liquid state at room temperature and pressure. Because it contains diethylamino groups, there are hydrogen bonds and van der Waals forces between molecules, but the strength of the forces is not enough to make it a solid state. Its melting point should be low, or near normal temperature. If the ambient temperature changes slightly, the morphology can be changed easily.
On its chemical properties, diethylamino groups have the property of electors, which increases the density of the electron cloud of the naphthalene ring, causing its chemical activity to rise, and it is easy to react with electrophilic reagents. In case of halogenated reagents, the halogenation reaction can occur at a specific position of the naphthalene ring; in case of acylated reagents, the acylation reaction can also be carried out. And because it contains dimethyl and diethylamino groups, the steric hindrance coexists with electronic effects, which affects the reaction check point and rate.
And because there are unsaturated naphthalene rings in the structure, with a conjugated system, an addition reaction can occur, such as with addition reagents such as bromine water, resulting in unsaturated bond saturation, changing the molecular structure and properties. In summary, 2% 2C4-dimethyl-1-diethylamino naphthalene is chemically active, and its physical properties are non-solid at room temperature, which is easily changed by the environment and reaction.

For 2% 2C4-dimethyl-1-diethylamino naphthalene, there are many ways to make it.
One method starts with naphthalene, first heating the naphthalene with acetic anhydride and anhydrous zinc chloride, and performing Fu-gram acylation reaction. The aromatic ring activity of naphthalene is quite high, and acetic anhydride can form an acylation product with the α-position of naphthalene under the catalysis of anhydrous zinc chloride. After that, zinc amalgam and concentrated hydrochloric acid are used to perform Clemson reduction reaction, which can acylate to alkyl to obtain 2-methylnaphthalene. Then dimethyl sulfate and a base are co-applied to 2-methylnaphthalene to methylate to obtain 2,4-dimethylnaphthalene. After halogenation, a halogen atom is introduced, and then it reacts with diethylamine. The halogen atom is replaced by diethylamino, and the final product is 2,4-dimethyl-1-diethylamino naphthalene.
Another method uses the corresponding halogenated naphthalene as a group. First, 1-halogen-2,4-dimethylnaphthalene is prepared. The activity of the halogen atom can be increased due to the conjugation of the naphthalene ring. When it is combined with diethylamine in an appropriate solvent, with a base such as potassium carbonate as an acid binding agent, heating and stirring, the halogen atom undergoes a nucleophilic substitution reaction with diethylamine, and hydrogen halide is bound by a base to form 2,4-dimethyl-1-diethylamino naphthalene. In this process, the choice of solvent is very important. Commonly used are toluene, DMF, etc., which can increase the solubility and reaction rate of the reactants.
Or other compounds are used as starting materials and prepared by multiple reactions. The way of organic synthesis often has various paths due to different raw materials and different conditions. All kinds of production methods, each with its own advantages and disadvantages, need to be based on actual conditions, such as the availability of raw materials, the level of cost, the difficulty of reaction and the amount of yield, etc., to choose the best and use it.

2% 2C4-dimethyl-1-diethylamino naphthalene, this material should be stored and transported with caution.
When it is stored, it is the first environment. It should be placed in a cool and dry place, away from fire and heat sources. Due to the risk of ignition and explosion in case of open flames and hot topics. In the warehouse, the ventilation must be good, and the temperature and humidity should be stable. If the temperature is high and humid, it may cause its properties to change and damage its quality.
Furthermore, it should be placed separately from oxidizing agents and acids, and must not be mixed. This is because of its active chemical properties, mixing with other things, or reacting violently, causing disaster.
When transporting, there are also many important rules. When handling, be sure to pack lightly and unload lightly to prevent damage to the packaging. If the packaging is damaged, the material will spill out, or cause danger, or pollute the surroundings. Vehicles used for transportation should be kept clean, dry, and free of residual sundries and chemicals. And during transportation, they should be protected from exposure to the sun, rain, and high temperature.
Escorts must have professional knowledge, understand its dangerous characteristics and emergency response methods. In case of emergencies, they can deal with it calmly and save themselves from danger. The means of transportation used should be hung with warning signs in accordance with regulations to alert everyone and make them alert. In this way, the safety of 2% 2C4-dimethyl-1-diethylaminonaphthalene storage and transportation is guaranteed, and accidents are avoided.
