Dioxo-chlorine is an important chemical raw material. It has a wide range of uses and is indispensable in many fields of industry and life.
In industry, dioxo-chlorine can be used to prepare a variety of compounds. For example, in the field of organic synthesis, it can participate in many reactions and help generate various organic substances with specific structures and properties. Due to its active chemical properties, it can interact with a variety of organic raw materials to promote the smooth progress of the reaction, and then prepare important chemical products such as pharmaceuticals, pesticides, and dyes.
Dioxo-chlorine also has excellent efficacy in disinfection and sterilization. It has strong oxidizing properties and can effectively kill bacteria, viruses, algae and other microorganisms in water. In the process of drinking water treatment, adding an appropriate amount of dioxo-chlorine can ensure the safety of water quality, remove the odor and color in the water, and compared with other disinfectants, it produces fewer by-products and is less harmful to the human body and the environment. In sewage treatment, it can also play a disinfection role, decompose organic pollutants in water, and improve the degree of purification of water bodies.
In the paper industry, dioxo-chlorine can be used for pulp bleaching. It can efficiently remove lignin from the pulp, improve the whiteness of the paper, and at the same time cause less damage to the fibers, which helps to maintain the physical properties of the paper. In this way, the quality and grade of paper can be improved to meet the needs of paper in different fields.
In addition, in the food processing industry, dioxo-chlorine can be used for disinfection of food processing equipment and food preservation. Disinfection of equipment can prevent microbial contamination of food; for food preservation, it can inhibit the growth and reproduction of microorganisms on the surface of food and prolong the shelf life of food.
To sum up, dioxo-chlorine plays a pivotal role in industrial production, public health, daily life and many other aspects. Its wide range of uses is of great significance to promoting social development and ensuring people's quality of life.

Dioxo-chlorine ($ClO_2 $) has unique physical properties. Under normal circumstances, it is a yellow-green gas with an irritating odor. This color and taste are distinct and easy to distinguish.
Its boiling point is quite low, about 11 dollars ^ {\ circ} C $, so it is easy to change from liquid to gaseous when heated. The melting point is $-59 ^ {\ circ} C $, and it condenses as a solid in low temperature environments. Because of its low boiling point, it mostly exists in gaseous states in normal temperature environments.
Dioxo-chlorine has good solubility in water and can be well soluble with water, which makes it advantageous in water-related treatment applications. However, it cannot be completely ionized in water, and only part of the ionization reaction occurs.
Furthermore, the density of dioxo-chlorine is higher than that of air. Therefore, if it leaks in an open space, its gas will tend to sink and accumulate. And because of its certain volatility, it can diffuse quickly in the air.
In addition, dioxo-chlorine has poor stability and is easily decomposed by heat or light, and can produce oxygen and other substances when decomposing. Due to its decomposition characteristics, when storing and using, it is necessary to take care to prevent heat and light, so as not to cause accidental decomposition, resulting in danger or reducing its active components.

Dioxo-chlorine ($ClO_2 $) has specific chemical properties and is unique among all substances.
Dioxo-chlorine has strong oxidation, which is its remarkable property. It can oxidize many substances and act as an oxidant in many reactions. If it encounters reducing substances, it can increase its valence state. In the field of water treatment, its strong oxidative sterilization and disinfection can remove bacteria, viruses and other microorganisms in water, and the effect is quite good, which has many advantages over traditional disinfectants.
Its stability is also considerable. Although it is oxidizing, it can maintain relative stability under specific conditions. However, when exposed to heat, light or certain catalysts, it is easy to decompose and release oxygen and other products. This property also makes it necessary to pay attention to the conditions during storage and use.
Dioxy chlorine is particularly oxidizing in acidic media. In this environment, it can more easily oxidize with a variety of substances, showing active chemical activity.
Furthermore, dioxy chlorine has a certain degree of volatility. Under normal temperature and pressure, it can evaporate into a gas. This property makes it useful in some gas-related reactions or application scenarios. And because of its volatility, it is necessary to pay attention to the ventilation of the space when using it to ensure safety.
Overall, the chemical properties of dioxo-chlorine are rich and diverse, and they have important uses in many fields. However, due to their characteristics, they must be handled with caution according to their properties and laws in order to achieve the expected effect and ensure safety.

The method of making carbon disulfide is described in "Tiangong Kaiwu". The method is as follows:
Take the stone gallbladder (that is, copper sulfate), and select those with pure texture, blue color and no impurities. The stone gallbladder is placed in a special crucible. The crucible is made of fire-resistant clay, which has good heat resistance. The crucible is covered with a cover of the same material, and the joints are sealed with mud to prevent gas from escaping.
After that, the crucible is placed in the stove and calcined with fierce heat. The stove needs to be carefully constructed so that the firepower is uniform and strong. When calcining, pay close attention to the heat, and do not rush or slow down. When the stone gallbladder is calcined at high temperature, the composition of it undergoes chemical changes, and gas is gradually formed. < Br >
The generated gas is introduced into the condensing device through a preset pipeline. The condensing device is made of metal and needs to have good thermal conductivity. When the gas is cooled in the condensing device, it condenses into a liquid, which is carbon disulfide.
However, in this process, the operation needs to be cautious. First, the selection of stone gallbladder is crucial. If the stone gallbladder is not pure, the prepared carbon disulfide also contains impurities, which affects the quality. Second, the heat control must be accurate, the heat is improper, or the reaction is incomplete, the yield is low, or the product is decomposed, and the pure product cannot be obtained. Third, the sealing and condensing links should not be neglected. If the seal is not strict, the gas will escape, which will not only waste raw materials, but also pollute the environment. If the condensation is not good, the product will be difficult to collect. < Br >
In this way, according to the method recorded in "Tiangong Kaiwu", carbon disulfide can be obtained through multiple processes.

One is dioxy and chlorine, which can be hidden and lost, so there are many people who should pay attention.
When hiding, the first thing to pay attention to is its utensils. It must be filled with strong and dense utensils to prevent leakage. Dioxy and chlorine are active in nature and easy to react with other things, so the utensils must be clean and rust-free, so as not to react with impurities and deteriorate. When placed in the same place, when protected from heat and light, these two can promote its change and cause instability. It is also suitable to hide in a cool and dry place to ensure its stability.
As for losing, the management must be firm and not leak. When losing, it should be slow, and it should not be rushed, for fear that it will risk life due to the drama. People should also be careful to wear protective gear, such as clothes, covers, gloves, etc., to prevent them from hurting their bodies. If you lose it in the room, it must be well ventilated to prevent it from accumulating, causing heavy breath and discomfort, or even life insurance. And when you are under supervision, you should always observe the state of the loss. If there is a leak or other changes, stop and deal with it.
Furthermore, when you are hiding and losing, you should be clear about its nature. Know the rules that should be followed, and you will not be in chaos when you encounter a change. Remember the law, follow the rules, and do not change it without authorization. In this way, you will ensure the safety of the two oxygen and one chlorine in storage and transportation, and you will be safe.
