The physical properties of tri-n-hexylphosphine are as follows:
The outer layer is usually a transparent liquid with a clear color to a light color. This is due to the characteristics of the molecular force and the molecular force. It has a certain viscosity. In the flow, the resistance of the molecular interaction is generated, and it shows a specific degree of viscosity. This viscosity is also the degree of phase. When the viscosity increases, the viscosity usually decreases.
The density of tri-n-hexylphosphine is slightly smaller in water. If it is mixed with water, it will float on the water surface. This is due to the density characteristics determined by the molecular weight and molecular arrangement. The boiling temperature is high, and the energy of the phase is required to make it melt from the liquid. Due to the existence of interaction forces such as van der force in the molecule, sufficient energy is required to overcome them.
Furthermore, trihexylphosphine has good solubility in polyphenyl solutions, such as benzene and toluene, which are non-soluble or weakly soluble. This is because due to the properties of its own molecules, the soluble molecules can form similar forces and follow the principle of similar dissolution.
Its surface force also has a specific value. On the surface of the liquid, the molecule is unevenly stressed, resulting in a certain force on the surface. This property affects its multiple lines at the interface, such as the surface and the like.
Therefore, the physical properties of tri-n-hexylphosphine are determined by their molecular formation, molecular interaction, and these properties play a crucial role in the application of chemical engineering and other fields.

Trin-butylphosphine is often used in many chemical reactions. In the field of organic synthesis, it is a commonly used reagent.
Because trin-butylphosphine has nucleophilic properties, it can participate in many nucleophilic substitution reactions. For example, in some halogenated hydrocarbon substitution reactions, trin-butylphosphine can launch a nucleophilic attack on the carbon atoms of halogenated hydrocarbons by virtue of its lone pair electrons on the phosphorus atom, causing the halogenated atoms to leave, thereby forming new carbon-phosphorus bonds or other carbon-heteroatomic bonds, which add to the framework of organic molecules.
In transition metal catalyzed reactions, trin-butylphosphine often acts as a ligand. After it is coordinated with the transition metal, the electron cloud density and steric resistance of the metal can be adjusted, which has a great impact on the activity and selectivity of the reaction. In the coupling reaction catalyzed by palladium, the appropriate tri-n-butyl phosphine ligand can enhance the activity of palladium catalyst, so that the coupling reaction with harsh reaction conditions can proceed smoothly under relatively mild conditions, greatly expanding the scope of application of the coupling reaction, and is of great significance for the synthesis of complex organic compounds.
In addition, tri-n-butyl phosphine can also play a role in free radical reactions. It can be used as a free radical initiator or free radical trapping agent to regulate the process of free radical reactions. In some systems that require precise control of free radical generation and reaction pathways, the unique properties of tri-n-butylphosphine make it an indispensable additive, enabling chemists to achieve the desired reaction goals and synthesize organic compounds with novel structures and unique properties.

The storage parts of the three positive and one base need to be stored in the place where they are stored to absorb moisture and prevent the growth of mold. This material is good in nature. If exposed to the hot sun, it is easy to disperse and has great effect.
The storage parts of the three positive and one base also need to be prevented from moth and mildew. The moth and one base should be damaged, and the mildew can be damaged. Both can be effective or even harmful. Therefore, the storage area should be covered with ash, and it can be placed to remove anti-mildew things, such as the dry stone ash, to absorb moisture and prevent the growth of mold; or put in fragrant grass, such as moxa, etc.
Furthermore, the three positive and one base should be stored in the warehouse, and it should not be mixed with others. Due to the different characteristics of each product, the mixed storage may affect each other and cause changes in performance. And it is necessary to have clear information, clear name, source, and collection information, etc., in order to access and investigate.
Tibetan utensils are also studied. It is appropriate to use containers with good density such as ceramic jars and glass bottles to isolate air and moisture to maintain the quality of the material. If transparent materials such as cloth bags are used, their properties should be preserved for a period of time. In this way, all important pieces of the three positive and one basic collection should be carefully handled to ensure their effectiveness.

The method of synthesizing three positive and one foundation is well covered. The description in "Tiangong Kaiwu" can be used as a reference.
One is to collect natural things to make it. Among the mountains and forests, find the quality of the three positive and one foundation, and pick it up. The ancient Fang family often went into the deep mountains and valleys to find strange grass and trees, among which there may be those who contain this wonderful thing. After obtaining it, the method of soaking in water and refining by fire, removing its impurities, extracting its essence, so that the three positive and one foundation gradually formed. If you get spiritual herbs, first soak them in a clear spring for a few days, wait for their quality to change slightly, and then place them in a pill furnace. Refining them slowly with a gentle fire. Control of the heat is very important. If you pass it a little, the quality will be destroyed, and if you don't get it, you will lose work. Finally, you will get a pure three positive and one foundation.
Second, it is made by combining various medicines. Choose products with medicinal properties and combine them according to a certain proportion. Ancient healers are proficient in pharmacology and know what medicines are suitable for the nature of three positive and one foundation. For example, with red herbs, green sandalwood, and white silver, supplemented by the foundation of profound soil, according to the number of five to three to two to one, they are placed in the pottery kettle together, add a spiritual spring, seal and boil. When you boil it, you need to stay by its side, watch its color change, smell its taste change, and wait for the color to be golden and the taste to contain a peculiar fragrance, so you can achieve good success. The proportion and heat of this need to be accurately grasped. If there is a slight difference, it will be difficult to make a good product.
Third, by taking advantage of the right time and the right place. At a specific time and place, make things naturally transform. For example, in the mid-spring month, the yang energy begins to flourish. On the slope of the sun, dig a shallow pit, put all the raw materials in it, cover it with fertile soil, and then use spirit talismans to suppress it. When the summer is over, the heat is in full swing, and the soil is broken to see it. If the raw materials have melted and have the appearance of three positive and one foundation, it will be successful. This is the principle of heaven and earth. With the power of nature, it is extremely difficult to choose the right time and place. It is not easy to do it unless you have the ability to clearly observe heaven and earth.
All these numbers need to be handled with heart and careful, in order to obtain the synthesis of three positive and one basic method.

Those who use the three positive and one foundation should not be careless when they are used. It is related to human life, and it involves disaster and good luck. All things should be paid attention to in detail.
The first method of processing. The three positive and one foundation is strong in nature, and it is difficult to remove its poison and save its effect. The process of processing should follow the ancient teachings, follow the season, and observe the heat to make the taste of the medicine peaceful and the toxicity will gradually disappear. For example, slow burning of mulberry wood, quenching it with spring water, repeated several times, before it can be used as medicine. The difference in the middle, or the change of pharmacogenicity, endangers life.
The dose is controlled every time. Those who use this medicine, the amount is related to life and death. It should be from less to more, step by step, and observe the patient's physical condition and symptoms in detail. When initially used, the amount should be extremely light, and the reaction should be observed. If there is any discomfort, stop taking it immediately, and do not act like a monkey wave. Doctors should weigh the pros and cons, prescribe cautiously, and do not increase the dose rashly for quick effect.
Furthermore, the beauty of compatibility. Three positive and one base cannot be used alone, but must be compatible with other medicines to control its bias and increase its curative effect. If used with licorice, it can slow down its severity; when matched with Angelica, it can adjust its qi and blood. The recipe for compatibility should be based on medical principles and experience, so that all medicines need each other and complement each other.
There is also post-drug care. After taking this medicine, the patient should rest and recuperate, avoid wind and cold, and save his diet. The diet should be light, and avoid spicy, greasy, and cold things to prevent conflicts with medicinal properties. And doctors need to visit often to observe the changes in symptoms and adjust the medication in time.
In general, the use of three positive and one basic medicine, processing, dosage, compatibility, and conditioning are all essential. Doctors should be in awe and study medical skills carefully, so as to ensure the safety of patients and the good effect of receiving medicine stones. They must not slack off a little, which will lead to disaster.
