Isoquinoline, 6,7-dimethoxy-1-veratryl-, hydrochloride (8CI)

I don't know what kind of product you are talking about, so it is difficult to understand its chemical structure. However, if it is said in the text of "Tiangong Kaiwu", it is probably as follows:
If you want to know the chemical structure of something, you need to carefully investigate its material, method and signs of change. "Tiangong Kaiwu" says: "Everything in the world is made of materials, and the properties of the materials and the clever method of making them are all related to the properties of the things." The chemical structure of a product should also start from the two.
Let's talk about the material first. The material is the basic element that constitutes this thing. There are many elements in the world, or gold, or wood, or water, or fire, or earth. Different elements are combined in different proportions and ways to produce all kinds of substances. For example, iron is collected from mountains and rivers, and it is obtained by the method of smelting and casting. Its chemical structure may be that iron atoms are arranged according to a certain law, and there may be impurity atoms mixed in between, resulting in different properties.
Second words method. The method maker, the shape and nature of the modified material, make it into the desired thing. Different methods can make the same material into products with different structures. For example, the method of firing porcelain, using clay as the quality, after material selection, billet making, glazing, and firing, the soil is turned into porcelain. Its chemical structure also varies depending on the firing temperature, time and atmosphere. During high temperature firing, the mineral components in the clay may undergo chemical reactions, and the atoms are rearranged to form a new crystal structure, resulting in the unique properties of the porcelain.
However, it is difficult to determine the exact chemical structure of the product only according to the material and preparation method. To understand, we must borrow various instruments and technologies. Although there are no precision instruments of today in ancient times, there are still methods of color observation, shape observation and testing to judge the properties of the product. Today, spectroscopy, chromatography, electron microscopy and other instruments can be used to analyze the atomic composition, molecular structure and spatial arrangement of the product in detail.
To sum up, if you want to know the chemical structure of a product, you need to test the material, preparation method, and use modern analytical techniques to understand it. Unfortunately, I don't know the product you are referring to, so I can't tell its exact chemical structure. If you can tell the name, material, preparation method, etc., you may be able to further analyze it.

The main use of this product is related to people's livelihood, and it also involves the work of hundreds of workers.
At the one end of farming, it can help cultivators reclaim the soil and turn the fields, so that the soil can be nourished and the crops can be flourishing. Ancient farmers relied on this utensil to open the streets, sow the grain, and pray for the prosperity of the year. Such as when sowing seeds in spring, use it to break the soil, introduce seeds into the soil, and help them take root and germinate; in summer and autumn, it is used for weeding the fields, protecting seedlings and ears, and making farmers prosperous.
In the industry of civil engineering construction, its role is also very important. Craftsmen can use wood cutting as beams and stone cutting as foundations. Building palace buildings, pavilions and pavilions all depend on its strength. In the case of wooden buildings, it can precisely cut the wood, so that the mortise and tenon fit seamlessly, making the house strong and beautiful; in stone, it can be carved into stone, and the columns and steps can be formed to build a magnificent building.
In the battle of soldiers and soldiers, it is also useful. It can be sharpened into a blade, and the sword can be used as a weapon for the soldiers to fight. In battle, the blade is pointed, and the enemy is defeated. Or it can be made into military vehicles and equipment, such as the parts of the crossbow machine, to enhance the combat power of armaments and protect the country and the state.
In daily chores, it is also indispensable. The home of ordinary people can be used to repair utensils, cut fabrics, and solve the needs of life. Home life, so as to repair tables and chairs, make boxes and cabinets to meet the various needs of daily living.
This product is widely used and plays an important role in the fields of agriculture, industry, military, and people. It is actually an essential tool for life and production.

The method of making a certain utensil was prepared in ancient times, but it is carefully studied in ancient books, and its methods are different. If you want to describe the system of this object today, you should learn from others to understand its method.
The husband makes this object, and the first material is selected. The quality of the material is related to the quality of the utensil. Those that are tough and durable must be selected, such as fine iron, good wood, etc. For iron, take its strength; for wood, take its flexibility. After the selection of materials is completed, it is time to enter the process of production.
At the beginning of its creation, it is necessary to review the shape. Or imitate the model of the previous generation, or create a new one from the machine. However, all should follow the principle of practicality, so that the shape of the utensil is convenient to use. If it is an appliance, consider the size and size, so that it is suitable and appropriate.
As for the work of making, each has its own needs. With iron tools, often through the method of smelting. First put the iron in the furnace, calcined with fierce fire, so that it can be flexible shape. When it is red, take it out and place it on the anvil to hammer it. The hammer method pays attention to light and serious diseases, and force is applied according to the shape, so that the shape of the device is regular. When forging, it is necessary to turn it repeatedly, so that all parts are evenly stressed, so as to avoid uneven thickness and defects.
If wooden tools are used, sawing, planing, chiseling, etc. are more commonly used. Sawing the wood to make it fit in length; planing it to make the surface smooth. As for chiseling and grooving, it is necessary to be precise, so as to fit the mortise and tenon. The method of mortise and tenon is an ancient skill, and it is not necessary to nail and rivet, but to make the body strong. When making, the mortise and mortise must fit perfectly, so that the utensil can be firm and durable.
The utensil is about to be completed, and it needs to be modified. Iron utensil, or ground with sand and stone to make it shiny; or lacquered to prevent rust. Wooden utensil, can be painted with varnish to show the beauty of its texture, and can protect the wood. < Br >
In short, the method of making this thing, material selection, shape review, workmanship, and decoration, are all interlocking and indispensable. It must be done carefully in order to become a beautiful and durable tool.
