First of all, those who use 2- (4-cyanobenzyl) -2-oxoethyl and 2-benzyl phosgene as raw materials need to follow various procedures. First take an appropriate amount of 2- (4-cyanobenzyl) -2-oxoethyl, place it in a clean reaction vessel, and then slowly add 2-benzyl phosgene. At the same time, observe the temperature, pressure and other variables of the reaction system, and adjust it in a timely and delicate way to ensure that the reaction is slow and orderly, so as to obtain better products. < Br >
Furthermore, there are also those who use 4-carboxyphthalic anhydride as the starting material. First, 4-carboxyphthalic anhydride is pretreated with specific pretreatment, or refined purification, or appropriate activation, so as to reach the desired state of the reaction. Then specific reagents are introduced. Under precisely controlled reaction conditions, such as exquisite control of temperature, length of reaction time, amount of catalyst, etc., the reaction is gradually initiated, so that the molecules interact according to specific chemical laws, and through a series of complex chemical changes, the final target product is obtained.
Or there are other synthesis methods, but all require precise proportions of materials and delicate control of reaction conditions. If the pH of the reaction environment is either weakly acidic or weakly alkaline, it will have a great impact on the reaction process and the quality and yield of the product. Therefore, in order to synthesize these compounds, all details need to be carefully considered, and the ideal results can be obtained with caution. The way of synthesis, such as walking in the subtle path, is prone to reaction errors, so it should be treated with rigor and specialization.

2 - (4 - hydroxyphenyl) - 2 - ethoxyethyl + 2 - phenylbenzyl ether - 4 - chlorobenzoic anhydride, its physical properties are as follows:
2 - (4 - hydroxyphenyl) - 2 - ethoxyethyl, this substance may be a colorless to light yellow liquid at room temperature, with a certain volatility. It is soluble in common organic solvents, such as ethanol, ether, etc. Due to the presence of both hydroxyl and ethoxy groups in the molecule, it has both a certain hydrophilicity and lipophilicity. Hydroxyl groups can participate in the formation of hydrogen bonds, causing their boiling points to be higher than hydrocarbons with similar molecular weights. This is due to the enhanced intermolecular forces.
2-Phenylbenzyl ether, usually white to slightly yellow crystalline solid, has a special aromatic odor. Its melting point is relatively high and stable at room temperature. Because its molecular structure contains benzene ring and benzyl group, it is insoluble in water, but easily soluble in organic solvents such as chloroform and dichloromethane. The conjugated structure of the benzene ring gives it certain stability and good resistance to light and heat.
4-chlorobenzoic anhydride, mostly white crystalline powder. The melting point is clear, and it can be melted when heated, and decomposed when further heated. Because its molecules contain chlorine atoms and acid anhydride structures, it has certain chemical activity. It is insoluble in water, hydrolyzed in hot water or slowly. Good solubility in organic solvents, such as acetone, ethyl acetate, etc. Because of its typical structure of acid anhydride, it can react with nucleophiles, and the presence of chlorine atoms also affects its reactivity and physical properties, making its melting point, boiling point, etc. slightly different from benzoic anhydride.
These numbers have different physical properties due to different structures and functional groups, and have their own unique uses and significance in organic synthesis and chemical industry.

4-Carboxylbenzaldehyde is an organic compound with many unique chemical properties.
It contains two key functional groups, aldehyde and carboxyl. The aldehyde group is active and can undergo many reactions. One is oxidation reaction. Under the action of suitable oxidants, aldehyde groups are easily oxidized to carboxyl groups, that is, 4-carboxylbenzaldehyde can be converted into 4,4 '-biphenyldicarboxylic acid. This reaction is often used in organic synthesis to grow carbon chains or build more complex carboxylic acid compounds. The second is a reduction reaction, where the aldehyde group can be reduced to a hydroxyl group. For example, when treated with a reducing agent such as sodium borohydride, the aldehyde group in 4-carboxybenzaldehyde can be changed to a hydroxymethyl group to generate 4- (hydroxymethyl) benzoic acid, which is very important in the preparation of organic compounds containing hydroxyl groups. The third is a nucleophilic addition reaction, in which the carbon and oxygen double bonds in the aldehyde group are susceptible to attack by nucleophiles due to the partial positive charge of the carbon belt. Like with alcohols in the presence of acidic catalysts, acetalization reactions will occur to form an acetal structure. This reaction is often used in organic synthesis to protect the aldehyde group from unnecessary oxidation or other side reactions in subsequent reactions.
The carboxyl group also imparts specific chemical properties to 4-carboxybenzaldehyde. It is acidic and can partially ionize hydrogen ions in water, showing the general properties of acids. It can neutralize with bases to generate corresponding carboxylic salts and water, such as reacting with sodium hydroxide to form sodium 4-carboxybenzoate and water. This property is widely used in the separation, purification and preparation of carboxylate compounds. At the same time, carboxylic groups can esterify with alcohols under the action of concentrated sulfuric acid and other catalysts to form esters and water, such as reacting with ethanol to form ethyl 4-carboxybenzoate. Ester compounds are widely used in flavors, coatings and other fields.
In addition, the benzene ring in the 4-carboxybenzaldehyde molecule can undergo electrophilic substitution due to the conjugated π electron system. Since both carboxyl and aldehyde groups are electron-withdrawing groups, the electron cloud density of the benzene ring decreases, and the reactivity decreases compared with benzene. However, under appropriate conditions, such as suitable catalysts and reaction temperatures, electrophilic substitution reactions such as halogenation, nitrification, and sulfonation can still occur, and the substituents mainly enter the meta-position of the benzene ring.

Today there are four things, called 2 - (4 - aminophenyl) - 2 - oxoethyl, 2 - phenylbenzyl ether, 4 - carboxypyridine, what is the price of the market?
The price of the husband's market often changes with time, varies with real estate, and is related to supply and demand. However, I do not know the current market median price of these four things.
These four things are all chemical things, and their price is determined by the price of raw materials. If the raw materials are easy to obtain and cheap, the price of these four things may not be high; if the raw materials are rare and difficult to collect, the price will be high.
Secondly, the difficulty of making is also tied to the price. If the preparation method is complicated, requires exquisite tools, superb skills, and takes a long time and consumes a lot of energy, the price will increase.
Furthermore, the demand of the market is also the main reason. If this product is needed by the pharmaceutical and chemical industries, the price may increase; if there is a lack of demand, the price may also decrease.
In addition, the origin is different, and the price is also different. Produced here, or due to the convenience of the geographical location, the cost is slightly lower, and the price is different elsewhere.
According to common sense, 2 - (4 - aminophenyl) - 2 - oxoethyl, 2 - phenyl benzyl ether, 4 - carboxypyridine, if used in high-end fields such as pharmaceutical research and development, due to strict requirements on purity, its price may not be expensive; if it is a common chemical raw material, and the output is quite abundant, the price may be slightly easier. However, if you want to know the exact price, you need to ask Jia people in the city, or check the price list of chemical materials, you can get it.
