I would like to know the chemical properties of alkane, (4-hydroxyethylphenyl) ethyl, and naphthalene. I should say it in ancient Chinese, and describe its properties.
Alkane, a genus of hydrocarbons, has saturation. Its carbon and carbon are connected by a single bond, and the structure is stable. At room temperature, it is mostly gaseous or liquid, and rarely solid. Its chemical properties are peaceful and it is not easy to react with other substances. In case of strong acids, strong bases, and strong oxidants, it can be safe. However, at high temperature or light, it can react with halogens. This is because light or high temperature causes halogen molecules to dissociate into free radicals, depriving hydrogen atoms in alkanes to form haloalkanes and hydrogen halides.
As for (4-hydroxyethylphenyl) ethyl, the structure of benzene ring and hydroxyethyl group. The benzene ring is aromatic and very stable. The hydroxyl group in the hydroxyethyl group is active and can react with acids by esterification, dehydration to form esters and water. And because of its benzene ring, it can react with electrophilic substitution on the benzene ring, such as halogenation, nitrification, sulfonation and the like. The electron cloud density of the capped benzene ring is high, which is easy to attract the attack of electrophilic reagents.
Naphthalene is also a fused ring aromatic hydrocarbon. It has a conjugated structure and is quite stable. Chemical properties are similar to benzene and can react with electrophilic substitution. Due to the uneven distribution of electron cloud density of naphthalene, the electron cloud density of α-position is higher than that of β-position, so the electrophilic substitution occurs mostly before the α-position. It can also react with strong oxidants to cause ring destruction. At high temperature, it can react with hydrogen to add and gradually form saturated cycloalkanes.
In summary, the alkalinity is smooth and there are many substitutions; (4-hydroxyethylphenyl) ethyl gene hydroxyl and phenyl rings can be esterified and electrophilic substitution; naphthalene is a fused cyclic aromatic hydrocarbon with electrophilic substitution, addition and oxidation. All have different properties due to their different structures.

"Tiangong Kaiwu" is a scientific and technological masterpiece written by Song Yingxing in the Ming Dynasty, which contains a lot of technological technology and production experience in detail. Arsenic, the chemical name is arsenic trioxide, a highly toxic substance. The following answers this question in classical Chinese form:
Arsenic has two main uses. First, in the field of medicine, although arsenic is poisonous, it can be used as medicine to treat diseases through exquisite processing and reasonable compatibility. Ancient physicians used arsenic to treat cold phlegm asthma, with its toxicity to remove phlegm and calm asthma; it was also used to treat swelling and poison in sores, using poison to fight poison to dissipate the poison and heal the wound. Today's medical research has found that arsenic has a unique effect in the treatment of leukemia, which can induce leukemia cell apoptosis and bring vitality to terminally ill patients.
Second, in the field of agriculture, arsenic can be used as an insecticide. In the past, farmers often suffered from bitter pests and damaged crops. The poison of arsenic can make pests kill when touched, die when eaten, and protect the growth of crops. However, its toxicity is fierce, and it is also easy to remain in the soil and crops, endangering the safety of humans and animals, so it is rarely used today.
As for (1-neon-2 - [ (4-acetamidophenyl) ethyl] - 4-pyridine), this chemical name is complex, and it seems that it is not known in the era of "Tiangong Kaiwu". At that time, science and technology did not reach this level, and it was difficult to have relevant records and applications. And the ancient books, many common things, practical techniques, such complex organic compounds, there was no reason to see, and no relevant use cases can be described.

To prepare this product, the method is as follows:
First, prepare all the required materials and utensils. The raw materials involved in this product are complex, 1-cyano- 2 - [ (4-ethoxybenzyl) methyl] - 4-bromobenzyl, and each component needs to be carefully selected to ensure that it is pure and free of impurities.
As for the preparation method, first deal with the (4-ethoxybenzyl) methyl part in a delicate way. In a suitable reaction vessel, in an appropriate proportion, mix the raw material containing ethoxybenzyl with the reagent that can introduce methyl groups. During the reaction, the temperature and duration need to be precisely controlled, and a little carelessness will cause the reaction to be biased. Or choose a mild catalyst to accelerate and stabilize the reaction, but the amount of catalyst should not be too much to avoid other changes.
Wait for (4-ethoxybenzyl) methyl to be prepared, and then combine it with 1-cyanogen-2-4-bromobenzyl. This step also needs to be careful and choose a suitable solvent so that each substance can fully contact the reaction. The pH of the reaction environment also affects, and can be fine-tuned according to the actual situation. During the reaction process, pay close attention to the signs of the reaction, such as changes in color and temperature, and judge the progress of the reaction accordingly.
After the reaction is completed, the follow-up treatment should not be underestimated. By proper separation and purification, the impurities are removed and the pure product is retained. Or by distillation, according to the different boiling points of each substance, separate them; or by extraction, the desired substance is extracted by the characteristics of the solvent. Finally, pure 1-cyano- 2 - [ (4-ethoxybenzyl) methyl] - 4-bromobenzyl can be obtained. The whole process requires the producer to be meticulous, and to be familiar with the principles of various reactions and the properties of various substances, in order to form this compound.

"Tiangong Kaiwu" says: Mercury is also a liquid of metal. If you want to properly store and transport mercury arsenide, you need to pay attention to many matters.
When storing, choose the first heavy container. Mercury arsenide is strong, perishable and easy to corrode, and needs to be stored in a special porcelain jar or lead jar. Porcelain cans are dense in texture and can resist the erosion of mercury arsenide; lead cans, because of their relatively stable chemical properties, can also effectively block the reaction of mercury arsenide with the outside world. The mouth of the can must be tightly sealed to prevent mercury arsenide from evaporating and escaping, causing toxic gases to overflow and injuring people and pests.
Furthermore, the storage place should be cool and dry, protected from the sun and heat. Mercury is easy to vaporize when heated. If the temperature is too high, it will not only lose materials, but also volatile mercury gas is highly toxic, endangering the surrounding life. And it is advisable to stay away from fire sources and flammable objects. When mercury is exposed to open flames or hot topics, it may react violently and cause disasters.
During transportation, package protection is extremely important. First, wrap the jar containing mercury in thick cloth or hay layer by layer to slow down the shock and prevent it from breaking due to collision. Then place it in a sturdy wooden or iron box, and fill the box with soft objects, such as cotton wool, shredded paper, etc., to further cushion.
The escort should be a professional who is familiar with the characteristics of mercury, and should know its hazards and emergency treatment methods. During transportation, it is also necessary to drive steadily and slowly to avoid sudden brakes and bumps. Once a leak is detected, it is quickly covered with sulfur powder, and mercury and sulfur are easily synthesized into mercury sulfide, which greatly reduces toxicity. Then it is properly cleaned up. Don't panic and cause harm to spread.
In short, the storage and transportation of mercury is related to human life and the environment, and it is necessary to be cautious and follow the law to ensure that nothing goes wrong.
