"Tiangong Kaiwu" is a scientific and technological masterpiece written by Song Yingxing in the Ming Dynasty. However, I have not found the exact records related to "this product 1-jiang-3-brand-2-aminocarbonyl naphthalene", so I can only answer you according to chemical knowledge and in the form of classical Chinese.
This "2-aminocarbonyl naphthalene" is an organic compound. Among its chemical properties, because it contains an amino group, it has a certain alkalinity and can react with acids. In case of strong acids such as hydrochloric acid, the amino group can combine protons to form a positively charged ionic structure. This reaction is similar to the combination of ammonia and acid.
Furthermore, the existence of carbonyl groups makes it electrophilic. Under suitable conditions, it can react with nucleophiles. In the case of alcohols, acetals or semi-acetals can be formed under the catalysis of acids or bases, which is a common reaction path in organic synthesis.
Its benzene ring structure also imparts certain stability to the substance, and at the same time enables electrophilic substitution reactions to occur on the benzene ring. Such as halogenation reactions, under the catalysis of appropriate catalysts such as iron filings, can be substituted with halogens, and halogen atoms replace hydrogen atoms on the benzene ring.
In addition, from the perspective of redox, the substance may participate in specific oxidation reactions, and carbonyl groups can be further oxidized to higher oxidation state structures such as carboxyl groups; amino groups may undergo oxidative transformation under specific conditions. Due to the characteristics of the functional groups contained in this "2-aminocarbonylnaphthalene", it exhibits a variety of chemical properties and may have important uses in organic synthesis and related chemical fields.

Cyanide, arsenic, and dimethylaminobenzene are all useful in various fields.
Cyanide, although highly toxic, is often used in the field of metallurgy to dissolve gold and other precious metals with cyanide. By virtue of its complexation with metal ions, gold is separated from ores. This is the key to gold extraction by cyanidation, and is widely used in mining gold. In chemical synthesis, it can also be used as a raw material to make nitrile compounds, which are indispensable in the production of synthetic fibers, rubber, plastics, etc.
Arsenic, that is, arsenic trioxide, although notorious for its toxicity, has also left traces in the history of medicine. In ancient times, it was used to treat scabies, syphilis and other diseases. Now, in the treatment of leukemia, arsenic-based drugs have been developed and improved, and the effect on specific types of leukemia is quite good. And in agriculture, trace amounts of Pi agent used to be an insecticide, but because of its strong toxicity, it has been used less today.
Dimethylaminobenzene is widely used in the dye industry. It is a raw material for the production of a variety of organic dyes. The dyes are bright in color and have good fastness. It is widely used in the textile printing and dyeing industry. In analytical chemistry, it can be used as an indicator, by which it reacts with specific substances to show color changes, to measure the pH of solutions or the content of specific substances.
All these things, although each has its own use, should be used with caution and in accordance with regulations to prevent disasters due to their toxicity or potential harm.

To prepare ethoxylbenzene, you can follow the following method.
First take an appropriate amount of phenol and place it in a clean reaction vessel. Phenol, an organic compound with a special odor. Then, prepare a solution of sodium ethanol and slowly add it to the container containing phenol. Sodium ethanol is a strong base and is an important reagent in this reaction. When the two meet, a nucleophilic substitution reaction can occur. The oxygen atom in the phenolic hydroxyl group of phenol is rich in electrons and has nucleophilicity, while the ethoxyl negative ion of sodium ethanol is also a nucleophilic reagent. The two interact, and the ethoxy group replaces the hydrogen atom of the phenolic hydroxyl group to generate ethoxylbenzene.
When reacting, pay attention to the regulation of temperature. Generally speaking, moderate heating can speed up the reaction rate, but if the temperature is too high, side reactions may occur. Therefore, the temperature is usually controlled within a certain range to make the reaction proceed smoothly.
After the reaction is completed, a mixed system containing ethoxylbenzene can be obtained. It may contain unreacted raw materials, by-products, etc. At this time, the operation of separation and purification needs to be carried out. Ethoxylbenzene can be initially separated by distillation using the difference in the boiling point of each substance. Because of its different boiling points from other substances, when heated to a suitable temperature, ethoxylbenzene can be first vaporized and collected after condensation. After that, it can be further purified by extraction, recrystallization, etc., to obtain pure ethoxylbenzene. In this way, the preparation of ethoxylbenzene is completed.

The state of the market is related to the price of all things, among which the price of ethanol is also expected by everyone. Ethanol has a wide range of uses and is important in industry, medicine, and people's livelihood, so its price changes will affect all parties.
When inquiring about the price of the ethanol market today, its price is not the same, because it is mostly determined by various factors such as its quality, origin, and supply and demand. If it is a city or an industrial grade, it focuses on industrial production because of its use, and its quality meets the standard of industrial use. The price often changes according to the prosperity of industrial demand and the abundance of raw materials. Pharmaceutical grade, because it is related to people's livelihood and health, strict quality requirements, and strict production regulations, so the price is higher than that of industrial grade, and it mostly depends on the state of the pharmaceutical market and policy regulations.
As for the current market, the price may vary from place to place. In prosperous cities, due to strong demand and convenient logistics, although the purchase price may be high, the sales volume is huge, and the price may be stable and moderate; in remote places, due to the difficulty of transportation, the difference in supply and demand, the price may fluctuate. Looking at the state of recent years, with the advance of technology and the emergence of new production methods, the cost may drop. If the supply of raw materials is sufficient, there is no sudden change, and the market competition is orderly, the price may be stable and decline. However, in the event of a natural or man-made disaster, a reduction in raw material production, or a sudden change in policy, the supply and demand imbalance, and the price may also rise sharply.
And the market price changes rapidly. If you want to know the exact number, you should consult local merchants, market brokers, or look at industry reports and official statistics to get the exact market price of ethanol at the moment.

In a certain valley, there is a medicine called dimethoxybenzene, and the conditions for its existence are quite important.
This medicine should be placed in a cool place to avoid its light exposure. Light, like a sharp blade, can break the stability of its molecules and cause them to deteriorate. The nature of medicine depends on the integrity of its molecules. If light disturbs it, the molecules will be chaotic and the medicinal properties will be lost. Therefore, in the room where you hide, the window should be small and covered with a thick curtain, so that light cannot enter.
It needs to be stored in a dry place. Water is the solvent of all things. When the medicine meets water, it may dissolve or melt, or change. In a wet environment, water vapor is diffused, and the medicine is easy to absorb moisture. After moisture absorption, or agglomeration, or mildew, the efficacy of the drug is greatly reduced. Therefore, in the place of Tibetan medicine, it is advisable to use lime and other substances to absorb moisture and keep it dry.
Furthermore, temperature is also critical. If it overheats, the molecules in the medicine will move quickly, and the reaction will be easy to start, causing it to decompose; if it is too cold, it may cause its structure to change easily. It is better to store it at room temperature, about 20 to 25 degrees Celsius. At this temperature, the molecular amps of the medicine will be stable in medicinal properties.
The package of medicine should not be ignored. When it is contained in a sealed container, it should be kept to prevent air from entering. Oxygen, carbon dioxide, etc. in the air can all respond to the medicine. A sealed device, such as a fortress, protects the medicine inside to protect it from air intrusion.
In summary, the storage of dimethoxybenzene requires yin, dryness, appropriate temperature and sealing in order to preserve its quality and effectiveness.
