The chemical properties of all things are related to their ability to change and react. Each thing is different, and it is especially complex. Looking at all kinds of utensils in the world, their chemical properties are special.
Gold is stable but not easy to melt, and can be settled in all environments. Although it is roasted by fire and soaked in water, it is difficult to change its quality. The ancients often used gold to cast utensils, because it does not rot and does not corrode, it can be handed down for a long time. "Kaogong Ji" says: "There are six levels of gold, and six points of gold and tin are one, which is called the unity of the bell and tripod." It can be seen that in the early Ming Dynasty, the combination of gold and tin can become a good weapon of the bell and tripod. This also involves the chemical properties of gold, which makes it durable after casting.
Iron is more lively than gold. Exposed to air and water, it is easy to rust and rot. This is because of the combination of iron and oxygen and water in the air. However, after iron is exercised, it can be combined with carbon and other elements to form steel. Its quality is tough and has a wide range of uses. The ancients made iron, using the skin to blast the wind to remove impurities in the iron, and adjust the amount of carbon, so that the steel that can be used can be used. This is because they are well aware of the chemical properties of iron and make good use of it.
Wood contains all kinds of organic components, which can burn and heat up. When it burns, it combines with oxygen to produce carbon dioxide and water. In ancient times, cooking and heating relied mostly on wood. And wood can be chemically treated to make paper. Cai Lun uses bark, pockmarked heads, cloth, fish nets, etc. as raw materials, through processes such as soaking, cooking, pounding, and copying to make good paper. This is also the clever use of wood's chemical properties.
Stone has a wide variety of types and different chemical properties. Limestone, calcined at high temperature, can become quicklime, which is the reason for the decomposition of calcium carbonate. When quicklime meets water, it produces cooked lime and puts a lot of heat. The ancients used lime to build walls and plaster surfaces, using its chemical properties to make walls strong.
Herbs and the like also have unique chemical properties. The ingredients they contain can interact with the physiological mechanism of the human body. Shennong tasted a hundred herbs to identify the properties of various herbs, which can cure diseases or be poisonous, all because the chemical substances contained in herbs are different from the reaction of the human body.
It is based on the chemical properties of all things, or it is beneficial to use, or it needs to be avoided, to understand its properties, and then it can be well managed to achieve the work of all things.

When using this utensil, pay attention to many matters. First and foremost, you need to use the method. Each utensil has its own system, and the usage method is also different. If you don't want it, it will not only be difficult to use it, but also damage the utensil. If you hold an axe, you must hold the handle firmly, and the force is orderly, so that the wood can be cut smoothly; when using a bow and crossbow, you need to be precise in the strength of the string and the method of aiming, otherwise you will miss the target.
Second rule, check carefully before use. Carefully examine whether the utensil is missing or damaged. A slight flaw may cause serious trouble when it is used. If you are driving, you must first check the axle and yoke. If there is a hidden disease, there may be changes on the way, endangering the traveler.
Furthermore, use it when appropriate. The use of utensils varies from situation to situation. For example, boats and boats are feasible on water, but difficult to travel on land; carriages and horses are convenient for land, and they are difficult to encounter in water. Therefore, the use of objects must depend on the situation they are in, and choose the one that suits them, so that they can be handy.
Repeat, maintain after use. Utensils are used, and wear and tear are inevitable. Timely maintenance can prolong their lifespan. When the sword is used, wipe them clean and oil them to prevent rust; put them in a dry place to prevent insects from decaying.
It should also be noted that each item has its own suitability and should not be abused. Forcing utensils to be impossible will only increase damage. If a saw is used instead of an axe, although the wood is wanted to be broken, it is inefficient and easy to damage the saw edge.
Where this object is used, it can be used for a long time by using the method of holding it, carefully inspecting it before use, adapting it at the right time, maintaining it after use, and not abusing it.

The process of preparing sodium 3- (N-ethyl-3-methylanilino) propanesulfonate (N-ethyl-N-sulfopropyl-m-toluidine sodium salt) is particularly exquisite.
Starting material, select m-toluidine and bromoethane as groups. First, m-toluidine is placed in a reactor and dissolved in an appropriate organic solvent to ensure uniform dispersion. Then, bromoethane is slowly added dropwise, and at the same time, the reaction temperature needs to be strictly adjusted to a specific range, which depends on the characteristics of the material and the reaction mechanism, and is accompanied by moderate stirring to promote its full contact reaction. The purpose of this step is to make the nitrogen atom of m-toluidine undergo nucleophilic substitution reaction with bromoethane to form N-ethyl-m-toluidine.
After the first step of the reaction is completed, the reaction solution is properly disposed, such as distillation to remove organic solvents and unreacted raw materials. After that, 1,3-propane sulfonolactone is introduced. In this step, a suitable reaction environment needs to be selected, such as a specific pH and temperature range. The active sulfonolactone group of 1,3-propanesulfonactone can rereact with the nitrogen atom of N-ethyl-m-toluidine to form 3- (N-ethyl-3-methylaniline) propanesulfonic acid through the nucleophilic ring-opening process.
The reaction is completed, and an appropriate amount of sodium hydroxide solution is used to neutralize the acid and base, so that 3- (N-ethyl-3-methylaniline) propanesulfonic acid is converted into 3- (N-ethyl-3-methylaniline) propanesulfonic acid sodium, and the target product is obtained. The product is recrystallized and other refining processes to improve its purity and ensure high quality. The whole process, each step is interlinked, and the conditions are precisely controlled to obtain this excellent product.

What is the approximate range of the market price of this product? To understand this, you need to look at many factors.
Looking at the raw material end, the quality and price of the raw material have a huge impact on the cost of the product. If the raw material is rare and difficult to pick, the price of the product will be high, and the price of the product will also rise. If the raw material is easy to obtain and cheap, the price of the product may also be close to the people.
Furthermore, the simplicity of the craftsmanship is also the key. Products that are carefully crafted and have complicated processes are time-consuming and laborious, and the craftsman's skills also need to be superb, and their price must be high. In the past, there were skilled craftsmen who made a delicate utensil over several years. It is not surprising that the price is as high as a thousand gold. And those with simple craftsmanship have lower costs and lower prices.
In addition, the state of supply and demand in the market also affects the price. If this product is in short supply in the market and everyone competes to buy it, the price will go up. If a novel thing first appears, everyone wants it, and its price will rise. If the supply exceeds the demand, merchants will sell it or reduce the price.
And brand reputation also has an impact. A well-known brand with a good reputation, its products are often more expensive than others because of their reputation. Everyone believes in its quality, so they are willing to pay a high price.
Overall, if the raw materials of this product are ordinary, the craftsmanship is ordinary, the market supply and demand are balanced, and it is not a well-known brand, the price may be between 100 yuan and several yuan. If the raw materials are rare, the craftsmanship is exquisite, the supply is in short supply, and it is a well-known product, the price may be dozens or even more. However, this is only a rough estimate, and the actual price needs to be studied in detail according to the specific situation.
