The physical properties of 2-% 4-ene-1-naphthyl-3- (trienyl methyl) benzene are as follows.
The shape of this compound is mostly solid under normal conditions, and its crystal form is high, the crystal surface is certain light, and the ground phase is low. Its melting characteristics are specific, and its precision is low at [X] ° C. This melting property can be used as an important basis for the preparation of this substance.
Its solubility is different in normal solubility. In ethanol, it is slightly soluble, the color of the solution is clear, but the solubility is limited; in dichloromethane, the solubility is excellent, and a homogeneous mixing system can be formed, which is convenient for dissolution or extraction. In water, this substance is dissolvable, and due to the characteristics of its molecules, the water molecules can form an effective interaction, and most of them settle in the bottom of the water.
The density of this substance is accurately measured, and the density is slightly higher. This property also affects its sedimentation or floating in different liquids.
Its performance is very weak, and it is often placed open to detect the appearance of the light. This is because the molecular force is low, and the energy required for the molecule to escape from the liquid surface is high.
In addition, the light and quality of this object are also worth noting. In the light environment, if the light is in the light, the short-term transformation can still be maintained; however, if the light intensity is high and long-lasting, or the part of the actinic reaction can be maintained, causing it to be changed. In case, before approaching its melting, the phase can still be maintained. However, if the degree of stability rises beyond a certain limit, it will cause decomposition and equalization to be reversed, causing its transformation to be irreversible.

The stability of the chemical properties of Fu 2-cyanogen-4-alkynyl-1-naphthyl-3- (trialkynyl methyl) naphthalene is an interesting question.
Such compounds contain functional groups such as cyanogen and alkynyl groups. Cyanyl groups have certain electronegativity, which can affect the electron cloud distribution of molecules, and their carbon-nitrogen triple bonds are quite active and can participate in many reactions, such as nucleophilic addition. Alkynyl groups also have unique activities. Due to the carbon-carbon triple bonds, addition and polymerization can occur. The two coexist in the molecule and affect each other, making the chemical properties of the compound complex and changeable.
Looking at the structure of naphthalene, it is an aromatic system with certain stability. However, in 2-cyanogen-4-alkynyl-1-naphthalene-3- (trialkynyl methyl) naphthalene, the naphthalene group is connected with the above active functional groups around the naphthalene group, and the electron cloud distribution is disturbed, and the aromaticity may change, and the stability is also different.
The introduction of trialkynyl methyl increases the complexity of the molecule. The accumulation of many alkynyl groups, the interaction of electron clouds, or the increase of molecular internal stress, further affects its stability.
In summary, the chemical properties of 2-cyanogen-4-alkyne-1-naphthyl-3- (trialkynyl methyl) naphthalene are difficult to say stable. The interaction of various active functional groups makes the molecule in a relatively active state, which is easy to participate in various chemical reactions. The stability is lower than that of simple aromatic compounds or simple hydrocarbons.

To prepare 2-cyanogen-4-pentene-1-carbonyl-3- (triamyl) benzene, the following ancient methods can be used.
First of all, all kinds of raw materials need to be prepared, such as cyanide-containing reagents, pentene structures, those that can provide carbonyl groups and triamyl-containing reactants. The materials must be pure and the amount must be accurately weighed. This is the basis for a smooth reaction.
In a clean kettle, first add an appropriate amount of solvent, which needs to be able to dissolve the reactants and not react with them. Common solvents such as ethers and hydrocarbons can be selected depending on the nature of the reactants. After the cyanide-containing reagent is slowly poured into the kettle, heated over low heat, and stirred at a constant speed with a stirrer, the reagent is evenly distributed among the solvents.
When the cyanide-containing reagent is dissolved in the solvent and heated to an appropriate degree, add the material with pentene structure and the one that can provide carbonyl in sequence. When adding, the speed should be slow to prevent the reaction from being too intense and out of control. After adding, the temperature in the kettle is maintained to stabilize, so that the three can fully react. During this process, the temperature, pressure, and color and state changes of the reaction in the kettle should be closely monitored to determine the progress of the reaction.
When the reaction in this step reaches the expected level, the temperature is cooled to a moderate level, and then the reaction containing triamyl groups is added to the kettle. After addition, the temperature and stirring rate are adjusted to further react with the first three. During this period, a little catalyst may be added to accelerate the reaction, but the amount of catalyst should not be too much to avoid side reactions.
At the end of the reaction, pour the mixture in the kettle into the separation funnel and extract the product with a suitable extractant. After extraction, the organic phase is collected, the water in it is removed with a desiccant, and then distilled and rectified to separate and purify the product to obtain pure 2-cyanogen-4-pentene-1-carbonyl-3 - (tripentyl) benzene.
The whole process requires careful operation and diligent inspection in order to produce high-quality products.

For 2-% N-4-ene-1-amino-3- (trienomethyl) benzene, there is a need to pay attention to it when it is stored in the warehouse.
First, this physical property or activity, it is easy to cause the surrounding environment to react. For the sake of survival, it is advisable to create a dry, dry, and well-connected place, and must not be near the fire source or the source, in order to prevent it from being reversed due to factors such as temperature and oxygen, resulting in the product being damaged.
Second, on the way, it should be properly packed. If this thing is solid, it should be stored in a sealed and moisture-proof container to avoid shock, collision, and prevent it from breaking or biochemical effects of the package. If the liquid is damaged, it is necessary to pay more attention to the sealing of the container to prevent leakage. And it should not be the same as those that are contrary to oxidation, acidity, etc.
Third, its shelf life is also controlled. Even if it is ideal for storage, it may not be changed after the passage of time. Therefore, it should be checked regularly, and a reasonable storage limit should be determined according to its characteristics and phase. If it expires, it needs to be added, and the situation should be determined whether it can be used.
Fourth, the operator must be subject to damage, and is familiar with the characteristics, danger and safety measures of this material. If it is stored or saved, it is necessary to prevent the use of emergency products and appliances. In the event of an accident, it can be quickly and properly treated, and the harm can be minimized. In this way, the safety of 2-% 4-ene-1-amino-3- (trienomethyl) benzene can be guaranteed during the storage process.
