It is one of the ends of things that is known by nature. Each of these two has its own similarity, and let me explain them one by one.
First of all, those who say that it is sour, this thing is often used in workshops. Its properties have the ability to decay, but if used properly, it can remove the damage of mechanical parts. Its taste is pungent, and its color is clear or slight. When it encounters gold, it can be soaked and surged, because of the reaction of acid and gold, and it can be released. Its liquid has good fluidity and is easily soluble in water, so the method of dilute is often used to control its degree to prevent the decay of utensils.
It is a weapon in the hands of craftsmen. It is easy to operate in deep gaps. It is easy to cut through wood, leather and other materials by using the method of quenching and piercing. Both are durable, and the surface is often used for anti-corrosion treatment, or paint, to ensure that it will not be damaged in daily use.

In this way, the acid is used to reduce the performance of the material, and it is used for cleaning and cleaning of utensils. It is easy to operate in deep gaps with a pointed mouth. It is easy to cut through wood, leather and other materials. Both are durable, and the surface is often used for anti-corrosion treatment, or paint, to ensure that it will not be damaged in daily use.
In addition, the acid is used to reduce the performance of the material, and it is used for the cleaning of utensils. It is based on the characteristics of the physical shape and material, and it is helpful for manual operation. The functions of the two are different, but they are all in the hands of craftsmen, each of whom is responsible for the work of creation.

(±) -10-Camphor sulfonic acid, its chemical properties are quite stable.
This is a chiral compound, which is widely used in the field of organic synthesis. Its stability is derived from its own chemical structure. The molecule of this substance contains a specific cyclic structure and functional group, which endows it with relatively stable characteristics.
From a molecular perspective, in the camphor sulfonic acid molecule, the sulfonic acid group (-SOH) is connected to the camphor skeleton. The sulfonic acid group has strong polarity, which can form intermolecular forces such as hydrogen bonds, which helps the intermolecular interaction and stable existence. At the same time, the rigid structure of the camphor skeleton also enhances the molecular stability, making the molecular configuration relatively stable and not easy to change easily.
Under normal conditions, (±) -10-camphor sulfonic acid can be stored for a long time without significant decomposition or deterioration. In common organic solvents, such as ethanol, dichloromethane, etc., it can maintain a stable dissolution state and does not chemically react with solvents, which facilitates its application in organic synthesis reactions. Even under some mild reaction conditions, such as within the appropriate temperature and pH range, it can maintain its own structural stability and play the role of chiral induction or catalysis.
However, like most chemical substances, its stability is not absolute. Under extreme conditions, such as high temperature, strong acid and alkali and other harsh environments, the structure of (±) -10-camphor sulfonic acid may be affected, and decomposition or other chemical reactions may occur. However, in normal laboratory operations and practical application scenarios, its chemical properties are stable enough to meet the needs of many organic synthesis and chiral resolution.

(±) -10-Trichoderate copper chelate should pay attention to the following things when storing and transporting:
First, moisture-proof is essential. This chelate is susceptible to moisture intrusion. If the humidity in the storage environment is too high, or if it encounters rain or moisture during transportation, it may cause its properties to change, and even affect its chemical properties and efficacy. Therefore, it is necessary to choose a dry place for storage, and take moisture-proof measures when transporting, such as wrapping it tightly with moisture-proof packaging materials.
Second, temperature must be careful. Temperature has a great impact on (±) -10-Trichoderate copper chelate. Excessive temperature or cause it to decompose and deteriorate, and too low temperature may change its crystalline form and affect subsequent use. It is usually suitable for storage and transportation in a room temperature environment. If there are special temperature requirements, it must be strictly followed.
Third, the anti-oxidation cannot be ignored. The chelate is in the air or reacts with oxygen, resulting in damage to its performance. When storing, it can be sealed and packaged to reduce contact with air; during transportation, it is also necessary to ensure that the packaging is well sealed to delay the oxidation process.
Fourth, avoid mixing and transportation with other substances. (±) -10-Trichodermic acid copper chelate or chemical reaction with certain chemicals, causing danger or reducing its quality. When storing and transporting, it should not be placed in the same place with acids, bases and strong oxidizing agents, and must be placed and transported separately.
Fifth, light loading and light unloading. During handling, care should be taken to avoid package damage due to collision, drop, etc. Once the package is damaged, not only the chelate is easily affected by external factors, but also may cause harm to the environment and personnel.

(±) -10-camphor sulfonic acid is an important chiral resolution agent and chiral auxiliary agent. Although its preparation method is not clearly recorded in "Tiangong Kaiwu", it can be deduced from similar processes and chemical principles in ancient times.
The preparation of ancient times often started with natural things. Camphor is taken from camphor wood and obtained by distillation. To obtain (±) -10-camphor sulfonic acid, or take pure camphor first, and prepare it by sulfonation. In ancient times, the sulfonating agent can be made from sulfur and saltpeter. The two are mixed and heated to obtain an agent containing strong oxidizing and sulfonating properties.
Place camphor in a special pottery kettle, slowly add the refined sulfonating agent, and heat it with a slow fire. The kettle needs to be airtight to prevent gas from escaping, and small holes need to be left so that the reaction gas can come out. When heating, keep stirring to make the camphor fully contact the sulfonating agent. Due to reaction or heat generation, it is necessary to control the temperature to prevent overheating from causing the decomposition of the product. Looking at the reaction, when the color state in the kettle is stable and seems to be a new product, it is not heated.
Then, the product in the kettle is leached with water, because (±) -10-camphor sulfonic acid is soluble in water, and impurities are mostly insoluble. The liquid after soaking is filtered with a fine cloth to remove its insoluble impurities. The filtrate is distilled to remove its moisture to obtain crude (±) -10-camphor sulfonic acid.
To obtain the refined product, you can recrystallize it. Choose a suitable solvent, such as a mixture of ethanol and water, dissolve the crude product, heat it until it is completely dissolved, and then let it stand and cool, so that the crystals slowly precipitate. The precipitated crystals are drained with a cloth to obtain a relatively pure (±) -10-camphor sulfonic acid. Repeated recrystallization in this way can obtain a high-purity product.
