1 2 Dichloro 4 Iodobenzene

Second, also known as koro sand, is a mineral. Its texture is unique and has the following physical properties:
Above the color state, it is mostly white, light gray-yellow or lavender-red crystalline powder, with a clean appearance and occasionally a sense of transparency. Under light, it has a bright luster, just like a finely crushed gem.
The hardness is not high, and it can be scratched with a fingernail. Its quality is crunchy, easily broken when hit, and the pieces are irregular.
The smell is weak, and the smell is slightly salty. Taste it, the taste of salty and bitter is obvious, but this mineral is toxic and should not be tried easily. < Br >
The density is moderate, and it can be weighed in the hand. It has a certain sense of weight. Its properties are easily soluble in water, and it dissolves quickly after entering water, and the aqueous solution is weakly alkaline.
Dixie was very important in the field of alchemy and medicine in ancient times. During alchemy, due to its unique physical and chemical properties, it can react with many drugs and assist alchemists in refining pills. In medicine, after being processed, it can be used as medicine to treat diseases, but due to its toxicity, it should be used with caution.
Sand is born in salt-containing halogen land and around mineral springs, and often coexists with minerals such as gypsum and stone salt. After mining, it needs special treatment and purification before it can be used in various fields.

Dixenon (1 dollar\% 2C2 - $dixenon - 4 dollars - $black) This substance is extremely rare and mostly involved in specific high-end scientific research situations. Its chemical properties are very unique.
The properties of dixenon, first, have strong oxidizing properties. Under specific conditions, it can react with many reducing substances. In case of active metals, electrons can be captured from the metal, causing the metal to be oxidized. Just like a warrior seizing other people's things, it shows its ability to seize electrons. Second, its compound structure is specific. Dixenon compounds, the internal atomic arrangement is different from that of common compounds, or they have a unique spatial configuration, which seems to build a unique pavilion, with atoms in their respective positions, forming a strange structure. Third, the stability is not conventional. Some dixenon compounds may be unstable at room temperature and pressure, and are easy to decompose; however, under special conditions, such as high pressure and low temperature, they can exist stably, like a spirit that adapts to a specific environment. If the conditions are not suitable, it will dissipate, and if it is suitable, it will survive. Fourth, the solubility also has characteristics. In some organic solvents, dixenon compounds may have a certain solubility and can be integrated into them, like salts soluble in water, but they vary according to the properties of the solvent. They may be soluble or insoluble in different solvents, and the laws are unique.
The unique chemical properties of dixenon are due to the special atomic structure and outer electron arrangement. This unique property has enabled researchers to continuously study it, hoping to explore more of its mysteries and create new frontiers for the field of chemistry. For example, explorers search for secrets in unknown places, find treasures, and promote the chemical discipline to move forward.

Disulfone tetrazole is mainly used in the fields of medicine and chemical synthesis.
In the field of medicine, disulfone tetrazole is often a key intermediate. Due to its unique chemical structure, it can participate in many drug synthesis reactions. For example, in the preparation of some antibacterial drugs, it can be cleverly combined with other chemical substances through specific reaction paths, giving the drug unique antibacterial activity and pharmacological properties. This can help the drug act more accurately on pathogens, enhance curative effect, and bring good news to patients.
In the field of chemical synthesis, disulfone tetrazole also plays an important role. In the synthesis of polymer materials, or as an initiator or modifier. As an initiator, it can effectively initiate polymerization reactions, promote monomer molecules to connect with each other, and form polymer, thereby improving material properties, such as enhancing material strength and heat resistance. As a modifier, it can interact with the molecular chain of polymer materials, change the surface properties and internal structure of materials, endow materials with new properties such as antistatic and wear resistance, greatly expand the application range of materials, and make materials available in electronics, automotive and other industries.
It can be seen that although disulfone tetrazole is a chemical substance, its wide application in the field of medicine and chemical synthesis has deeply affected people's lives and industrial development, providing a solid boost for the progress of many industries.

The two-nitrate powder is a good medicine for treating blister scabies. The method of its preparation is quite exquisite, and the details are as follows:
First, take one tael of realgar. It is better to choose one with pure color and fine texture. Take one tael of orpiment again, and also seek high quality. Another two taels of sulfur should be prepared, and this sulfur must be pure and free. Study this three flavors into a very fine powder. When studying, you should concentrate on it, so that the powder is as fine as dust, and it is qualified.
Second, put the three taels of yellow wax into the pot and boil it slowly. When the wax melts into a liquid and flows like a liquid of gold, slowly pour the previously developed powder into the wax liquid. At this time, you need to use a wooden spoon to keep stirring, so that the powder and the wax are fully integrated, just like water emulsion blending, without the slightest feeling of particles.
Third, after stirring evenly, remove from the heat and let it cool slightly. When the temperature is suitable and it is not hot, rub it into pills. The size of the pills is generally appropriate, such as mung beans. When rubbing the pills, you should be skilled in the technique and strive for an even size of each pill.
After making this pill, take it with warm water, three pills each time, twice a day. This two-nitrate powder is properly prepared, and it will have a significant effect on the disease of blisters. However, when making medicines, all kinds of materials and steps need to be treated with caution, and there should be no slack in order to get good medicine to cure the disease.

Dioxy and dioxy are essential for the storage of natural gas.
Dioxy is sexually active and corrosive. For storage, it is necessary to keep a dense container to prevent exposure. This device is resistant to corrosion. If the dioxy is not released, it will not endanger the surrounding things and be harmful to people. In addition, if it is stored in the environment, it will avoid fire and high temperature. Because of its exposure to open fires, high temperatures, or dangerous conditions. It is also necessary to prevent the leakage of relevant fire-fighting equipment, and to take proper measures to avoid strong shocks and collisions.
Dioxy is the source of drugs, which is prohibited by law. It is not allowed by law. No matter what the reason is, it should not be involved in this matter. The harm is very great, and it affects the body and mind of the people, the order of the society, and the safety of the family. Therefore, it is absolutely necessary not to have the idea of saving rice, and it must be done quickly. In order to ensure the safety of the world, the health of the people should be ensured. In addition, the two oxygen industries need to be cautious, and the rice crops should not be involved in half.
