4-Benzoylpyridine is an organic compound. It has unique physical properties, which are described in detail by you.
First of all, its appearance, under room temperature and pressure, 4-benzoylpyridine is mostly white to light yellow crystalline powder. This color state is easy to identify with the naked eye. In laboratory or industrial production, its purity and state can be preliminarily judged based on this.
times and its melting point, about 106-108 ℃. Melting point is an important physical constant of a substance. At this temperature, 4-benzoylpyridine melts from solid to liquid. This characteristic can be used to identify the substance, and in the process of separation and purification, its purity can be judged according to the melting point. If the melting point of the sample is consistent with the standard value and the melting range is narrow, the purity is higher; conversely, if it deviates from the standard or the melting range is wide, it contains more impurities.
Another is the boiling point. Although the exact boiling point data is affected by factors such as environmental pressure, it is roughly within a certain range. The boiling point is related to the temperature at which it changes from liquid to gaseous state under a specific pressure. This property is crucial in separation operations such as distillation. It can be set according to the appropriate temperature to achieve effective separation of 4-benzoylpyridine from other substances.
Solubility is also an important physical property. 4-benzoylpyridine is slightly soluble in water, but can be soluble in common organic solvents such as ethanol, ether, chloroform, etc. This difference in solubility has application value in many processes such as chemical synthesis and extraction. For example, in the post-treatment of synthesis reactions, it can be used to separate products and impurities by taking advantage of its different solubility in different solvents, and a suitable solvent can be selected for extraction.
In addition, 4-benzoylpyridine has a certain density. Although the specific value is also affected by temperature and other conditions, this property is indispensable for accurate measurement and calculation of its mass and volume relationship. In the process of material ratio between experiment and production, the density data provides the basis for accurate operation.
In summary, the physical properties of 4-benzoylpyridine, such as its white to pale yellow crystalline powder appearance, specific melting point, boiling point, solubility and density, are of critical significance in chemical research, industrial production and many other fields, laying the foundation for its preparation, separation, purification and application.

4-Benzoylpyridine is one of the organic compounds. The stability of its chemical properties is related to many factors, which are described in detail as follows.
From the perspective of molecular structure, 4-benzoylpyridine contains a pyridine ring and a benzoyl group. The pyridine ring is aromatic, and its structure tends to be stable because the π electron cloud in the ring conforms to the 4n + 2 rule. In the benzoyl group, the benzene ring also has an aromatic stable structure. Although the carbonyl group has a certain activity, it is conjugated with the benzene ring to enhance the stability of the whole group. The two are connected, and the overall stability of the molecule is improved.
In the chemical environment, the stability of 4-benzoylpyridine is affected by various conditions. Under normal temperature and pressure, if there is no special chemical reagent to interact with it, its properties are relatively stable. However, in the case of strong oxidants, such as potassium permanganate, the carbonyl group of benzoyl may be oxidized, resulting in structural changes. In the case of strong acids and bases, pyridine cyclic nitrogen atoms or protonation, or nucleophilic substitution with bases, etc., affect its stability.
Temperature is also a key factor. At high temperature, the thermal motion of molecules intensifies and the vibration of chemical bonds increases, making 4-benzoylpyridine more prone to react and its stability decreases. In low temperature environments, the reaction rate slows down, which helps to maintain its stability.
Solvent has a significant impact on its stability. In polar solvents, molecules or solvation changes the charge distribution, which affects the stability. In non-polar solvents, the interaction is weak, which is relatively more conducive to maintaining the stability of the original structure.
In summary, the stability of 4-benzoylpyridine is not absolute, and it is relatively stable at room temperature, without special reagents and suitable solvent environments; in case of special chemical conditions, temperature changes, etc., the stability may be damaged.

4-Benzoylpyridine is 4-benzoylpyridine, which is synthesized by various methods. I will describe it in detail today.
First, pyridine and benzoyl chloride are used as raw materials, and under the action of appropriate catalysts, this compound can be formed. In this reaction, the nitrogen atom of pyridine is nucleophilic, and the carbonyl carbon of benzoyl chloride is electrophilic. When the two interact, the chlorine leaves, forming a carbon-nitrogen bond, and then 4-benzoylpyridine is obtained. Pay attention to the reaction conditions, such as temperature, choice of solvent, and high or low temperature, which may affect the reaction rate and yield. The polarity of the solvent also affects, and the polar solvent may help the reaction to proceed.
Second, by the method of organometallic reagents. First prepare an organometallic reagent containing pyridyl groups, such as pyridine Grignard reagent, and then react with benzoyl halides or benzoate esters. Organometallic reagents have high activity and good reactivity with carbonyl compounds. However, when preparing organometallic reagents, an anhydrous and anaerobic environment is required, otherwise it is easy to react with water and oxygen, resulting in the failure of the reagents.
Third, pyridine derivatives and benzene derivatives are used as starting materials and synthesized through multi-step reactions. For example, pyridine and benzene are first functionalized, and then the structure of 4-benzoyl pyridine is gradually constructed by condensation, oxidation and other reactions. Although this approach is complicated, it can precisely regulate the structure of the product. If other specific substituents need to be introduced, this method may have advantages.
When synthesizing 4-benzoylpyridine, the advantages and disadvantages of each method should be weighed according to actual needs and conditions, and the optimal one should be selected to achieve the purpose of efficient and high-purity synthesis.

4 - benzoylpyridine, chemical substances are also. However, the price in the market often varies depending on the purity of the product, the amount supplied, and the situation of demand.
If you ask for its price, in the past in the world of "Tiangong Kaiwu", there was no such thing in the market. Today is different from the past. In the chemical market, the price range is pure, the highest, or tens of yuan to more than 100 yuan per gram; the pure second, the price or low, ranging from a few yuan to a few tens of yuan per gram.
The price of chemical materials is mostly due to the cost of production, transportation, and taxation. The cost of production involves the mining and manufacturing of raw materials. If the raw materials are thin and the manufacturing process is complex, the cost will be high, and the price will also be high. The cost of transportation is related to the distance, the method of transportation, the distance and the special transportation. The cost will increase, and the price will follow. The amount of tax levied is also a variable of the price.
And the supply and demand of the market have a huge impact. If you want to be prosperous and the supply is small, the price will rise; if you supply too much, the price will be suppressed. Therefore, if you want to know the price of 4-benzoylpyridine, when you check the actual news of the city, consult the suppliers and business operators, you can get the accurate number.
