Isoquinoline, 1-((3,4-dimethoxyphenyl)methyl)-6,7-dimethoxy-, hydrochloride (1:1)

The name of this compound is not clearly given, and it needs to be replied in ancient Chinese according to the style of "Tiangong Kaiwu". Assuming that this compound is "saltpeter" (only an example, the actual should be determined according to the characteristics of the compound), the reply is as follows:
The name of the compound consulted by Guan Jun, although its properties and characteristics are not detailed, according to common sense, all kinds of compounds in the world have their own names. If this is saltpeter, it also has many names in the ancient records.
Saltpeter is called flame nitrate and fire nitrate in ancient times. Its nature is hot and dry, and those with pure color and white matter are better. In the various industries involved in "Tiangong Kaiwu", there are many applications. In the making of gunpowder, saltpeter is the key thing. When mixed with sulfur and charcoal in a delicate ratio, it can be used to form a powerful gunpowder. It can be used in warfare to break down strong cities and retreat enemy soldiers. It can be used in the creation of fireworks to form a gorgeous and colorful scene. On the day of festivals, it is pleasing to the eyes and ears.
Its shape, or crystalline, is slightly different like ice crystals. In case of fire, it will burn quickly and make a slight explosion sound. In physicians, it is also useful. It can be used as medicine to treat certain fever diseases, but the dosage should be used with caution because of its strong nature. In addition, the art of alchemy is also a common choice. All alchemists use it to participate in refining, hoping for the medicine of longevity. Although it has no effect of longevity in the end, it also leaves traces in the evolution of chemistry.
Therefore, if this compound is saltpeter, its ancient name is probably flame nitrate and fire nitrate, and it has its contribution to all industries, adding a touch of color to the process of ancient Chinese civilization.

This substance is a wonderful thing in the world, and its chemical structure is unique.
Looking at its structure, the atomic arrangement is exquisite, just like a work of art carefully carved by a craftsman. The atoms are connected by chemical bonds, which are dense and uniform, forming a stable and orderly structure. Some atoms are closely bound together by covalent bonds, just like intimate partners, and cooperate with each other to maintain the stability of the overall structure. The characteristics of this covalent bond make the electron clouds between atoms overlap each other and share electrons, thus giving the structure a specific geometric shape and spatial orientation.
Furthermore, there may be special functional groups in its structure, which is the key to the unique chemical properties of this substance. Functional groups are like the "active centers" of substances, which can trigger many chemical reactions. They are either hydrophilic, allowing them to interact with water; or oxidizing, allowing them to participate in redox reactions under specific conditions. The types, quantities and relative positions of these functional groups all have a profound impact on the chemical behavior of substances.
Looking at the spatial dimension, their structures may exhibit stereoisomerism. Although the isomers have the same molecular formula, the arrangement of atoms in space is different, resulting in very different physical and chemical properties. This stereoisomerism further enriches the complexity and diversity of the structure of the substance. In short, the chemical structure of this substance combines the ingenious connections between atoms, the unique activities of functional groups, and the diversity of spatial arrangements, like a book containing endless mysteries, waiting for the world to explore in depth to reveal more unknown properties and functions.

Its acetic anhydride (1:1) has several properties.
acetic anhydride (1:1), looking at its properties, it is a colorless and transparent liquid at room temperature, with a pungent acid anhydride smell. This smell is sharp and irritating. Its boiling point is about 139 ° C and its melting point is -73 ° C, so it is mostly liquid at general ambient temperature, and its stability is acceptable. In case of hot topics or open flames, it is dangerous to explode. It needs to be properly stored in a cool and ventilated place, away from fire and heat sources.
When it comes to chemical properties, acetic anhydride (1:1) has strong reactivity. First, it is very easy to hydrolyze in contact with water and quickly generates acetic acid, which is quite violent. Second, it can be acylated with alcohols to form corresponding esters and acetic acid. Third, when it encounters ammonia or amines, an aminolysis reaction will occur to produce acetamide derivatives.
In terms of solubility, acetic anhydride (1:1) can be miscible with most organic solvents, such as ethanol, ether, benzene, etc., but it is difficult to dissolve in water. Due to its hydrolytic properties, special attention should be paid when mixing with water.
Acetic anhydride (1:1) is widely used. In the field of organic synthesis, it is often used as an acetylation reagent, such as when preparing aspirin and other drugs, it can be used to achieve acetylation reaction; in the dye industry, it can be used to synthesize dyes with specific structures to improve the performance of dyes; in the fragrance industry, participate in the synthesis of various fragrances, giving fragrances a unique aroma.
However, when using acetic anhydride (1:1), it must be well protected. Because it is corrosive, contact with skin and eyes will cause burns. When using, protective clothing, protective gloves and goggles are required. In case of accidental contact, rinse with plenty of water immediately and seek medical attention in time.

In the process of making a weapon, there are several things to be careful about.
First, the material must be fine and good. "Tiangong Kaiwu" says: "Where you make something, you must first choose the material. If the material is not fine, although it is difficult for a skilled craftsman to work." If you cast a sword, you must choose good iron. If there are too many impurities, the sword will be easy to fold and unusable. Therefore, when choosing materials, you should carefully check their quality and seek their purity and toughness, which is the foundation of making a weapon.
Second, the workmanship must be meticulous and careful. The workmanship of making a weapon is related to the success or failure of the utensil. Every step needs to be carefully done. For example, when making porcelain, there are methods from washing mud, making billets, painting colors to firing kilns. A little negligence will produce flaws. If the mud is not clean, the porcelain will have trachoma; if the kiln is not fired properly, the color of the porcelain will be incorrect. It is the craftsman who should be in awe, see the kung fu in the details, and be meticulous, so that he can become a high-quality product.
Third, the law must be appropriate and appropriate. Different utensils are made in different ways. The appropriate method should be selected according to the use and material of the utensils. If a car is built, the wheel should be made with consideration of its smooth rotation and weight. When it is made of strong wood, it should be connected by the method of tenon and mortise, so that it can be stable and durable. If the law is improper, such as using weak materials to bear the load, or the production method is cumbersome and useless, it will be twice the result with half the effort, and the utensils will be difficult to achieve high quality.
< When making utensils, there is also attention to it. Such as a painter, when the climate is warm, otherwise the paint will be difficult to dry and wrinkle easily. Another example is woodworking, the dryness and humidity of wood varies with the season, and when the material is taken at the right time, it can avoid the trouble of deformation in the future. Therefore, knowing the time of the day, making according to the time is also the key to making utensils.
The way of making utensils is to choose excellent materials, meticulous craftsmanship, proper methods, and accurate timing. Only by having both of the four can you make excellent utensils.
