To prepare 5-alkene-2-acetoxyacetophenone-3-carboxylic acid, the method is as follows:
First, a series of organic reactions can be used to construct carbon chains and functional groups. Start with suitable starting materials, or compounds containing alkenyl groups and benzene rings. For example, select an alkenyl benzene derivative and use an acylation reaction to introduce an acetoxy group. This acylation reaction can be carried out in the presence of a suitable acylation reagent, such as acetyl chloride or acetic anhydride. The catalyst can be selected from Lewis acid, such as aluminum trichloride, etc., to promote the efficient occurrence of the reaction, so that the acetyl group is precisely attached to a specific position of the benzene ring, to obtain benzene derivatives containing alkenyl and acetoxy groups. < Br >
Then, the carboxylation reaction can be carried out. The Grignard reagent method can be used to prepare the intermediate containing magnesium halide first, and then react with carbon dioxide. After hydrolysis, the carboxyl group is successfully introduced into the molecule, and the final result is 5-ene-2-acetoxyacetophenone-3-carboxylic acid.
Second, another idea can also be started. The compound containing carboxyl group and phenyl ring is first constructed, and the carboxyl group is converted into a suitable active intermediate through a specific reaction for subsequent reactions. At the same time, the alkenyl part is introduced by alkenylation reaction. There are many alkenylation methods, and the suitable one can be selected according to the raw material and reaction conditions, such as the reaction of alkenyl halide with metal reagents. After that, the acetoxy group is introduced. In this step, the acylation reaction method can be used to precisely adjust the reaction conditions, so that the acetoxy group is attached to the target position, so as to achieve the synthesis of 5-ene-2-acetoxyacetophenone-3-carboxylic acid.
During the synthesis process, each step of the reaction needs to pay attention to the control of the reaction conditions, such as temperature, solvent, and ratio of reactants. If the temperature is too high or too low, it may cause abnormal reaction rates or the formation of by-products; the choice of solvent is also critical, and its properties such as polarity and solubility will affect the process and selectivity of the reaction; the accurate allocation of the proportion of reactants can ensure that the reaction proceeds in the expected direction and improve the yield and purity of the target product.

The author of "Tiangong Kaiwu" was written by Song Yingxing in the Ming Dynasty, and it is also a book of various technological products. However, "5-Jiang-2-Aminoethoxypyridine-3-sulfonic acid" is not involved in it, and there is no fine product of this chemical synthesis in ancient times. If you want to know the market price of this product today, you should use the current commercial market as the basis.
In today's world, the price of chemicals often depends on multiple factors. First, the cost of raw materials. If the raw material of "5-Jiang-2-aminoethoxypyridine-3-sulfonic acid" is easy to obtain and abundant in production, the price may be inexpensive; if the raw material is scarce and difficult to collect and refine, the price will be high. Second, the production process. The preparation of this compound requires delicate and complex processes, multiple processes, strict equipment and technical requirements, high energy consumption, and its cost increases and the price is high; if the process is simple and easy to operate, the price may be close to the people. Third, the supply and demand of the market. If the demand for this product is strong in the fields of medicine, chemical industry, etc., but the supply is limited, the so-called "rare is expensive", its price will rise; if the market demand is low and the supply is sufficient, the merchant will sell its goods, or reduce the price in order to sell.
In addition, the price of "5-Jiang-2-Aminoethoxypyridine-3-sulfonic acid" of different qualities is also different. High purity is suitable for high-end scientific research and precision chemical industry, and its price must be higher than that of ordinary purity. And the price varies depending on the place where it is sold. In prosperous commercial ports and chemical centers, the price may tend to be reasonable due to a lot of competition and convenient logistics; in remote places, the price may be slightly higher due to transportation costs.
To determine its market price, you can consult chemical raw material suppliers, chemical product trading platforms, or refer to relevant industry reports and market survey data to obtain more accurate prices.

"Tiangong" cloud: Mercury, also known as water, is toxic. Mercury derivatives 2-methoxypyridine and 3-boric acid are not stored in the world, so it is very important to pay attention to things.
Mercury and its derivatives are not stored, and the first thing to do is to seal. Because it is easy to seal, if the seal is not good, mercury will evaporate and escape, which will not pollute the environment and endanger personal safety. Therefore, it is necessary to use a sealed container to avoid the risk of damage. In addition, where it is suitable for storage, it will dry up. Mercury and its derivatives are sensitive to the degree and temperature, and it is easy to react to high moisture, causing it to change.
On the way, the package must be firm. Mercury derivatives are often dangerous, and it is easy to cause the container to break. Therefore, they need to be properly wrapped with special packaging materials to prevent their leakage. In addition, people must be well-versed in the characteristics of mercury and derivatives, which are dangerous. In case of accidents and leaks, etc., it can be tolerated. According to the correct process management, the harm is minimized.
In addition, if it is not stored or not, it is necessary to comply with the relevant laws and regulations. The management of this chemical substance is strict, and the operation does not violate the law, and it is more difficult to save it. Only with caution and careful consideration can we ensure the safety of mercury and derivatives such as 2-methoxypyridine and 3-boronic acid.
