What is the main use of Tri-n-butylphosphine?
Tri-n-butylphosphine has a wide range of uses. In the field of organic synthesis, it is often used as a reducing agent. It can convert compounds containing carbonyl groups, such as aldodes and ketones, into alcohols. This is because tri-n-butylphosphine has the property of reducing, which can give electrons and promote the reduction of carbonyl groups by acquiring electrons.
Furthermore, in the reaction catalyzed by transition metals, tri-n-butylphosphine also plays an important role. It can be used as a ligand to complex with transition metals, thereby adjusting the electron cloud density and spatial configuration of metals. In this way, it can significantly affect the activity and selectivity of catalytic reactions. For example, in some coupling reactions, tri-n-butylphosphine complexes formed with metals such as palladium can efficiently catalyze the formation of carbon-carbon bonds, which is of great significance for the construction of complex organic molecular structures.
In materials science, tri-n-butylphosphine is also used. When preparing some semiconductor quantum dots, it can be used as a stabilizer and surface modifier. It can adsorb on the surface of quantum dots to prevent quantum dot agglomeration, improve the stability and optical properties of quantum dots, and then make quantum dots better used in many fields such as Light Emitting Diode and biological imaging.
In addition, in the study of organophosphorus chemistry, tri-n-butylphosphine is an important starting material and intermediate. With the help of it, many organophosphorus compounds with diverse structures can be synthesized, which have potential applications in the fields of medicine, pesticides, and flame retardants.
What are the physical properties of Tri-n-butylphosphine
Tri-n-butylphosphine has a general physical property. Under normal conditions, it can be reduced to a light-colored liquid, and this color has one of its characteristics. Its taste is specific, and it has a stimulating taste, and its particularity can be known by smelling.
In terms of density, it is 0.827 g/cm ³, which makes it a specific fraction of water in some liquid-liquid mixtures. Its boiling temperature is 154-156 ° C, at this degree, tri-n-butylphosphine is reduced from liquid to liquid. And melting temperature is -60 ° C, below this degree, it solidifies.
Furthermore, the solubility of tri-n-butylphosphine is also special. It is soluble in many soluble substances, such as ether, toluene, chloroform, etc., but it is soluble in water. This poor solubility is of great significance in the chemical operation. Its steaming effect is also an important physical property. The size of the steaming effect determines its qualitative and anti-activity in different environments to a certain extent. This physical property is based on the use of tri-n-butylphosphine.
What to pay attention to when storing and transporting Tri-n-butylphosphine
Tri-n-butylphosphine is a reagent commonly used in organic synthesis. When storing and transporting it, many matters must be paid attention to.
First words storage. This substance is highly reducing and easily oxidized by oxygen in the air, so it should be stored in an air-isolated environment. An airtight container filled with an inert gas (such as nitrogen) can be used to prevent oxygen intrusion. In addition, tri-n-butylphosphine is quite sensitive to moisture and reacts easily in contact with water, so it must be kept dry in storage to prevent it from deteriorating due to moisture absorption. Temperature is also critical. It should be stored in a cool place, away from high temperature environment, because high temperature can cause its reactivity to change, or even cause adverse reactions such as decomposition.
As for transportation. Be sure to ensure that the packaging is tight during transportation to prevent leakage. Because of its irritation, if it is accidentally leaked, it will not only damage the environment, but also pose a threat to human health. At the same time, the transportation process should also maintain a stable environment to avoid large temperature fluctuations and violent vibrations. Transport personnel must be professionally trained, familiar with the characteristics of tri-n-butylphosphine and emergency treatment methods. In case of emergencies, they can be disposed of in a timely and proper manner to ensure the safety of transportation. Overall, when storing and transporting tri-n-butylphosphine, it should not be ignored in terms of air isolation, dryness, temperature control, tight packaging, and professional personnel, so as to ensure its quality and safety.
What are the safety risks during the use of Tri-n-butylphosphine
Tri-n-butylphosphine (Tri-n-butylphosphine) in the course of use, there is no such thing as safety,
First, this material is flammable. Tri-n-butylphosphine is flammable in case of open flame and high flammability, just like the fire of ancient times, it will ignite in case of fire. Its evaporation can form explosive mixtures, such as in the ambush of the dark, it will explode instantly in case of fire source. If it is not careful, the spark will cause an explosion.
Second, it is harmful to human health. Inhalation, such as poison into the lungs, can cause respiratory irritation, coughing, respiratory distress; if the skin is exposed, it resembles acid, which can cause skin burning, pain; eye contact, such as sharp arrows, can cause severe irritation, and even harmful force. Phase or reverse contact, more like chronic toxicity, may affect the functions of organs such as the body, the liver, etc.
Third, environmental hazards should not be ignored. Once tri-n-butylphosphine leaks into the environment, such as pollution into the river, it is very toxic to aquatic organisms, causing a large number of deaths in aquatic organisms, breaking the aquatic balance, and it degrades in the environment, persists, and endangers the environment.
Therefore, when using tri-n-butylphosphine, it is necessary to be deep and walking on thin ice, and to maintain the safe operation process and take anti-dumping measures to avoid harmful effects.
What are the preparation methods of Tri-n-butylphosphine
The preparation method of tri-n-butylphosphine (Tri-n-butylphosphine) is a common method in ancient books. One method is to use n-butylphosphorus trichloride as a raw material. The n-butylphosphine is dripped into the solution of phosphorus trichloride. This step needs to be carried out in a low-temperature and inert environment to prevent the reaction from getting out of control and the raw material is oxidized. The butyl part of the n-butylphosphine gradually replaces the chlorine atom in the phosphorus trichloride to generate tri-n-butylphosphine in multiple steps. This reaction requires precise control of the reaction degree, the proportion of raw materials and the dripping speed, and whether it is easy to produce side effects.
There is also a method of using butanol and phosphorus trichloride as a starting material. First, the reaction of butanol and phosphorus trichloride under the action of suitable catalysis is made to generate a medium-sized compound, and then the reaction is reduced in one step to obtain tri-n-butylphosphine. In this way, it is necessary to pay attention to the amount of catalysis. The amount of catalysis can effectively promote the reaction. However, if the amount is too much or too little, it may cause undesirable effects on the reaction rate and rate. And in the reaction process, the extraction of the medium-sized compound also needs to be precisely grasped.
Another method is the Grignard method. Using butyl bromide (Grignard) and phosphorus trichloride reaction, and reasonably controlling the reaction, tri-n-butylphosphine can also be obtained. In this process, Grignard needs to be in a dry environment, and it is easy to fail. And phosphorus trichloride reaction, the same should pay attention to the reaction degree, reaction and other factors, in order to ensure the production and yield of the target material. Therefore, the general method of preparing tri-n-butylphosphine has its own requirements, and it needs to be improved according to the needs of the product.
