Bis (diethylaminoethoxy) phenylpropane, often referred to as 2 - (diethylaminoethoxy) phenylpropane, is a controlled psychotropic substance. At the time of the publication of Tiangong Kaiwu, there was no such substance. However, with current knowledge, its main use is stated.
2 - (diethylaminoethoxy) phenylpropane, in the field of medicinal chemistry, or involved in the production of psychotropic drugs. Its molecular structure contains specific functional groups, or is related to the action of neurotransmitters, so it may be potentially useful in the development of specific psychotropic drugs. For example, in the exploration stage of some antidepressant and antianxiety drugs, such structures may be used as lead compounds, modified and optimized to find the ideal balance of activity and safety.
In scientific research experiments, it may be used as a tool compound to help scientists explore the mechanism of nerve conduction and receptor action. With its unique structure, it may simulate and interfere with the binding of neurotransmitters and receptors, observe the physiological reactions of cells and tissues, and contribute to the theory of neuroscience.
Of course, because of its psychoactivity, abuse is prone to addiction, dependence and serious health problems, such as nervous system disorders, cardiovascular abnormalities, etc. Therefore, it is strictly regulated around the world, and can only be used in scientific research and medical settings in compliance with strict procedures. The production, sale and illegal use all touch the legal red line, aiming to protect public health and social stability.

The physical properties of di (diethylamino) carbonyl phenyl silicon are as follows:
This substance is mostly solid at room temperature, and it is usually white or off-white crystalline powder with fine texture and smooth touch. Its melting point is quite critical, about a specific temperature range. This property is of great significance in identification and purification. With the help of melting point determination, its purity can be preliminarily determined.
In terms of solubility, di (diethylamino) carbonyl phenyl silicon exhibits unique solubility properties in common organic solvents. In some organic solvents, such as toluene and chloroform, it can present a good dissolution situation and form a homogeneous and clear solution. This characteristic makes it better dispersed in the reaction system in organic synthesis reactions, as a reactant or intermediate, and promotes the smooth progress of the reaction. However, in water, its solubility is very small and almost insoluble, which is closely related to the hydrophobicity of the organic groups in its molecular structure.
In addition, di (diethylamino) carbonyl phenyl silicon has a certain density. Although its density data is not often the focus of attention like melting point and solubility, density information is also indispensable in specific chemical production processes, such as material ratio, mixing and phase separation operations, which can help to accurately control the production process and ensure uniform and stable product quality. Its physical properties such as appearance, melting point, solubility, and density together constitute the basic characteristic framework of this substance in the field of chemistry, laying a solid foundation for its application in many fields such as organic synthesis and materials science.

To prepare 2 - (diethylaminoethyl) naphthol, there are three methods.
One is to start with naphthol, and to react with 2 - chloroethyl diethylamine in alkali, nucleophilic substitution. This reaction condition is peaceful, but the activity of naphthol may be insufficient, resulting in a slow reaction rate and a high yield. When reacting, it is necessary to choose an appropriate alkali agent, such as potassium carbonate, sodium carbonate, etc., and to find a suitable solvent, such as N, N - dimethylformamide, dimethyl sulfoxide, etc., to promote the reaction.
The second is to start with 2-naphthyl acetone, first reduce to 2-naphthyl ethanol, and then replace it with diethylamine to obtain the target. 2-Naphthyl acetone is easy to obtain, and both reduction and substitution reactions are common methods. However, the reduction step may require specific reducing agents, such as sodium borohydride, lithium aluminum hydride, etc. The operation needs to be careful, because lithium aluminum hydride reacts violently in contact with water, which is dangerous. The substitution reaction also needs to control the conditions, such as temperature, time, proportion of reactants, etc., to obtain the best yield.
The third method is to use 2-bromonaphthalene and 2-diethylaminoethanol as materials, under the catalysis of palladium, to conduct a coupling reaction. The coupling reaction catalyzed by palladium is efficient and selective, and high-purity products can be obtained. However, the palladium catalyst is expensive, the reaction cost is high, and the oxygen-free environment is required, which requires strict reaction equipment and operation. In the reaction, aptamers and bases need to be selected to increase the activity and selectivity of the catalyst.
The third method of preparing 2 - (diethylaminoethyl) naphthol has its own advantages and disadvantages. In actual preparation, when the availability of raw materials, cost, yield and purity are required, the method of selection is suitable.

Bis (diethylamino) ethyl ether needs to pay attention to many matters during storage and transportation.
For storage, one should find a cool, dry and well-ventilated place. This is because the substance may be sensitive to heat and humidity, high temperature and humid environment may cause it to undergo qualitative change, and even cause safety risks. Second, keep away from fire and heat sources. Because of its flammability, it is easy to burn in case of open flames and hot topics, which will cause fires and endanger the safety of the surrounding area. Third, the storage container must be tightly sealed. To prevent it from evaporating into the air, one is to avoid loss, and the other is to prevent it from reacting with air components. If the volatile gas reaches a certain concentration, there may be a risk of explosion. Fourth, it should be stored separately from oxidants, acids, etc. Due to its chemical properties, contact with these substances is very likely to cause violent chemical reactions, resulting in dangerous conditions.
As for transportation, first of all, the transportation vehicle must ensure that the vehicle is in good condition and has reliable safety facilities and fire fighting equipment. In this way, in the event of an accident during transportation, timely response measures can be taken. Secondly, the transportation process needs to be careful to avoid collision and dumping. Because it is a liquid, collision, dumping or damage to the container, the material leaks. Once leaked, it not only causes losses, but also may pollute the environment and threaten human health. Furthermore, transportation personnel need professional training, familiar with the characteristics of the substance and emergency treatment methods. If there is an emergency during transportation, the transportation personnel can deal with it quickly and effectively according to the knowledge they have learned to reduce the degree of harm. Finally, the transportation must strictly follow the relevant regulations, drive according to the designated route, and do not change it at will to prevent stopping in densely populated areas or environmentally sensitive areas to reduce latent risks.

Mild cases, or allergies, skin itching, erythema suddenly arise, disturbing people's peace. In severe cases, it may damage human organs. The liver, the detoxification center of the human body, may be overloaded and the function is damaged due to metabolism of this drug. The kidney, an important place for excreting waste, may also be affected by it, resulting in excretion dysfunction.
Worse, long-term exposure to this drug may increase the risk of cancer. Modern medical research has gradually revealed that certain chemicals can cause mutations in human cells and induce carcinogenesis. 2-%28%E4%BA%8C%E6%B0%9F%E7%94%B2%E6%B0%A7%E5%9F%BA%29%E7%A1%9D%E5%9F%BA%E8%8B%AF%E8%8D%AF%E7%89%A9%E4%B9%8B%E5%88%86%E5%AD%90%E7%BB%93%E6%9E%84, or interact with key targets of human cells, interfere with the normal physiological process of cells, causing uncontrolled cell proliferation and eventually carcinogenesis.
Therefore, when using this drug, be cautious. Drug users should adhere to strict regulations, and environmental monitors should monitor them frequently, so as to ensure the tranquility of the environment and personal health.
