Benzoic Acid, 4-fluoro-2-iodo-

4-1-2-heptylbenzoic acid is a unique compound with interesting chemical properties and diverse characteristics.
In this compound, alkyl (-OH) and alkynyl (- C ≡ C -) benzoic acid coexist, making its properties and characteristics. The alkyl group has water-based properties and can be polymorphic, such as esterification. Under suitable conditions, the alkyl group can react with carboxylic acids or their derivatives to form ester compounds. This reaction often requires catalysis, such as sulfuric acid, etc., which can be used under additives.
The alkynyl group does not work together and is active. It can generate additives such as sulfuric acid and chemical additions. Taking bromine as an example, the alkynyl group can be added to it, and gradually form dibromogenates and even tetrabromogenates. This reaction is usually performed in inert solutions such as carbon tetrachloride to ensure the inversion. And alkynyl groups can be used in gold-catalyzed even reactions, such as Sonogashira, etc., which are used in the field of synthesis.
The presence of benzoic acid makes it have a certain degree of stability. However, benzene can also be replaced by benzene. For example, under the catalysis of powder or trioxide, it can be replaced by benzene, and benzene atoms can be introduced into benzene. The carboxyl group (-COOH) is acidic and can be used to generate neutralization and inversion to form a phase. The same, the carboxyl group can also be esterified, acylated and other inverse compounds, and multiple compounds can be derived.

To make 4-ene-2-ketobenzoic acid, the following ancient methods can be used.
Take the derivative of benzoic acid first, and choose the appropriate one, such as those with modifiable functional groups. If a benzoate is used as the starting material, benzoic acid can be obtained by hydrolysis. During hydrolysis, use alkali to participate in the reaction, such as sodium hydroxide solution, to control its temperature, concentration and reaction time. The temperature should not be too high to avoid side reactions. It is about a moderate range, such as between 40 and 60 degrees Celsius, for about two hours. After the reaction is completed, neutralize with acid to obtain benzoic acid.
Then, introduce the structure of ene-2-ketone at the carboxyl ortho-position of benzoic acid. The ortho-halogenated benzoic acid can be obtained by halogenating the ortho-position of benzoic acid with a halogenated reagent, such as a brominating agent, in a suitable solvent, such as carbon tetrachloride, under the help of light or a catalyst. The amount of halogenating agent used needs to be accurately weighed, and the molar ratio to benzoic acid should be an appropriate value, such as 1.2:1, to ensure that the halogenation reaction mainly occurs in the ortho-position.
Then the ortho-halogenated benzoic acid is reacted with the related reagents of ene-2-ketones. This step can be catalyzed by metal-organic reagents. For example, a palladium catalyst, a dialkenyl borate, is used as a donor of an alkenyl-2-ketone structure, and it is reacted in an organic solvent such as N, N-dimethylformamide with the help of a base. The base can be selected from potassium carbonate, etc. The reaction temperature is controlled at 80-100 degrees Celsius. After several hours, the halogen atom is coupled with the alkenyl-2-ketone structure to obtain 4-alkenyl-2-ketobenzoic acid. After the reaction, the pure product is obtained by separation and purification methods, such as column chromatography, and a suitable eluent.
This whole process needs to abide by the rules of operation and control the conditions of the reaction, so that 4-ene-2-ketobenzoic acid with higher yield and purity can be obtained.

4-Ketobutyric acid, that is, β-hydroxybutyric acid (β-Hydroxybutyric acid), should pay attention to the following things in the storage of this substance:
First, the degree is very important. Beta-butyric acid or due to the degree of waves, it is suitable for the place where it is located, usually at 2-8 ℃. If the degree is high, it will melt or be broken, and the activity will be reduced; if the degree is low, it may cause it to solidify and affect the product. If it is hot in summer, it must be refrigerated to control the temperature and maintain its quality.
Second, avoid light. The reaction of light or β-butyric acid accelerates its degradation. The storage container should be made of dark-proof materials, such as brown glass bottles, and the container should also be covered with a light-shielding material to prevent direct light.
Third, keep the dry environment. Beta-butyric acid has a certain water absorption, and the moisture environment is easy to make it absorb moisture, resulting in an increase in water content, no accuracy of shadow, and may promote the growth of microorganisms. Therefore, it is necessary to prevent rain and dew from invading.
Fourth, pay attention to the density of the container. Beta-butyric acid is easy to contain components in the air, such as oxygen, causing oxidation and modification. The storage container should be well sealed, and it should also be checked before storage to ensure that it does not leak or be exposed during the transportation.
Fifth, store it in isolation. Beta-butyric acid cannot be combined with acid, alcohol and oxidation. Because of its activity, this substance cannot be connected or caused by strong reactions, which is dangerous.

4-Jiang-2-Shao, formic acid, what is the price of the market?
Fu 4-Jiang-2-Shao, formic acid, is used in medicine, and its price in the market often changes due to many reasons. The origin is different, the price is different. If the product is rich and of good quality, the price may be slightly flat; if the area is remote and the production is thin, the price will be high.
It varies from season to season, and it is also related to its price. If it is appropriate to harvest, it will be available to the market, and the price may drop; if it is not at the right time, the goods will be few and the price will rise.
And the quality is the key to the price. Those who are refined and pure, the price is high; those who are inferior in quality, the price is low.
At present, the price of 4-Jiang-2-Peony, formic acid, is about fifty to hundred dollars per catty. However, this is only a rough number, and the market conditions change constantly, or fluctuate with the price. When merchants are buying and selling, they must carefully observe their situation, and measure the origin, season, and quality, so as to obtain their appropriate price, so as not to be deceived by the market.
