Diborane is an inorganic compound with unique physical properties. It is a colorless gas at room temperature and pressure, with a specific and toxic odor. The boiling point of diborane is quite low, about -92.5 ° C, due to the weak intermolecular force. Its melting point is also low, about -165.5 ° C, reflecting the loose arrangement of molecules.
Diborane has a lower density than air, and can rise lightly in air. Because of its very low boiling point, it is highly volatile, and requires very little energy to change from liquid to gas. And diborane has very little solubility in water, which means that its molecular structure and water molecule polarity are quite different, making it difficult to form effective interactions with water.
The volatility of diborane makes it diffuse rapidly, and it is easy to mix with air in a limited space. Its flammability is also significant, and it is very easy to burn and explode in case of open flames and hot topics. When burned, a bright flame is produced and a large amount of heat energy is released. This combustion reaction is intense, due to the rich chemical energy of boron-hydrogen bonds in diborane, which can be released quickly when reacted with oxygen.
In addition, diborane has high reactivity and can chemically react with many substances. For example, it can react with metals, non-metallic elementals and various compounds. When participating in organic synthesis reactions, it is often used as a reducing agent or a reagent to provide boron atoms, showing unique chemical behaviors. This is due to the electron cloud distribution and valence state characteristics of boron atoms in the molecular structure of diborane. In short, diborane plays an important role in the field of chemistry due to its physical properties such as low boiling point, low density, high volatility, flammability and high reactivity.

Iridium and osmium alloys are a genus of rare and precious metals, and their chemical properties are particularly unique.
Iridium has extremely high chemical stability, and it is difficult to react in many common chemical reagents at room temperature. Strong acids such as hydrochloric acid, sulfuric acid, nitric acid, etc., even if they are concentrated, they cannot be easily eroded. In aqua regia, although it can act slowly, its corrosion resistance is still very strong compared to other metals. This property is due to the stable electronic structure of iridium, and the outer electrons are difficult to be taken away, resulting in its low chemical activity.
The chemical properties of osmium are also quite stable, and they have strong tolerance to most acids. However, in the presence of oxidizing agents, such as co-heating with hydrogen peroxide, potassium chlorate, etc., volatile osmium tetroxide can be formed, which is highly toxic and has a special odor.
Iridium-osmium alloys combine the characteristics of both, not only excellent chemical stability, but also because of the synergy effect of the two, they can still maintain their chemical stability under harsh environments such as high temperature and strong corrosion. This property makes iridium-osmium alloys widely used in chemical, electronics, aerospace and other fields. For example, in chemical catalytic reactions, it can be used as an efficient and long-lasting catalyst. Due to its stable chemical properties, it is not easy to be consumed or deteriorated during the reaction process. In the electronics industry, it is used to manufacture corrosion-resistant electrodes, touchpoints and other components to ensure the stable operation of electronic equipment. In aerospace, it is used to manufacture engine components, etc., to resist chemical attack in extreme environments.
In short, iridium-osmium alloys, with their extraordinary chemical stability, occupy an indispensable position in many key areas of modern science and technology, providing a solid material foundation for the progress and development of science and technology.

When using an aldehyde solution, be sure to pay attention to the following safety precautions:
First, the aldehyde is highly flammable, and its evaporation and air can form an explosive mixture. Therefore, in the place of use, it is necessary to strictly prohibit smoke and fire, and the electrical equipment used should be explosion-proof. All operations should be carried out in the cabinet to effectively prevent the evaporation and accumulation of aldehyde and reduce the risk of explosion. If you need to use fire or carry out operations that may produce fire flowers, you must first clear the workplace to ensure that the evaporation concentration of aldehyde is reduced to a safe range, and strictly abide by the specifications of the fire operation, and apply for the approval of the fire in advance.
Second, the aldehyde has a certain poison to the human body. Its steam or fog can irritate the eyes, skin and respiratory mucosa. Therefore, when using it, you must be fully armed, wear suitable protective clothing, protective hand covers and protective glasses, and if necessary, wear anti-virus equipment. If you accidentally touch the aldehyde, you should immediately rinse with a large amount of water. If the aldehyde enters the eyes, you need to seek medical attention immediately after rinsing. If you inhale the aldehyde and steam, you should quickly evacuate the scene to a fresh place in the air to keep the respiratory tract unobstructed. If you have difficulty breathing, you need to give oxygen in time; if you stop breathing, you should immediately apply human breathing and send for medical treatment.
Furthermore, the aldehyde is volatile. When storing, it should be placed in a cool and well-ventilated warehouse, away from fires and heat sources. The storage temperature should not exceed 25 ° C, and it should be stored separately from oxidants, reducing agents, acids, etc., and should not be mixed. The packaging of formaldehyde must also be tightly sealed to prevent its volatilization and escape. At the same time, the storage place should be equipped with leakage emergency treatment equipment and suitable containment materials. In the event of aldehyde leakage, personnel from the leaked contaminated area should be quickly evacuated to the safe area, and quarantined, and strictly restricted from entering and leaving. Emergency personnel must wear self-contained positive pressure breathing apparatus, wear fire protection clothing, and cut off the source of leakage as much as possible. For small leaks, activated carbon or other inert materials can be used to absorb; in the case of large leaks, embankments or pits should be built for containment, covered with foam to reduce evaporation disasters, and then transferred to a tanker or a special collector with an explosion-proof pump, recycled or transported to a waste treatment site for disposal.

Thiocyanate, with spicy and irritating properties, has many methods, and each has its own subtle method, which is described below.
First, thiocyanate is used instead of thiocyanate. This is a commonly used method. Thiocyanate, such as thiocyanate or thiocyanate, such as thiocyanate, thiocyanate, etc., are mixed in a suitable solution. Under a certain degree of stability and catalysis, the two nuclei are replaced by thiocyanate, and the thiocyanate atom is replaced by thiocyanate to form thiocyanate. For example, ethyl thiocyanate can be obtained by refluxing bromoethane thiocyanate in ethanol. In the reaction, it is necessary to pay attention to the dissolution of the reaction, so as to facilitate the full dissolution of the reaction without reaction; the degree also needs to be controlled, and the high or low temperature may affect the reaction rate and the yield of the reaction.
Second, the amine compound is carbon disulfide, and it is replaced by carbon disulfide. First, the amine and carbon disulfide are reversed under the reaction of the compound to form dithiocarbamic acid. In this step, it can be oxidized, carbonated, etc., to promote the reaction. However, the dithiocarbamate is replaced by the reaction, and the molecules are rearranged to form thiocyanates. For example, in the presence of carbonate, aniline and carbon disulfide are first reversed to form anilinyl dithiocarbamate, and then iodomethane is reversed. Phenyl thiocyanate can be prepared. In this way, it is necessary to pay attention to the accuracy of each step, the dosage of the reaction, the degree of reaction, and the degree of reaction, etc., which are all important for the formation of reaction.
Third, the reaction of sulfur light is made from sulfur light. The activity of sulfur light is high, and the compound of sulfur can quickly react to form thiocyanate. However, the toxicity of sulfur light is very low, and the operation needs to be carried out under the anti-corrosion of the grid, and the proportion of anti-corrosion materials needs to be carefully controlled. If methylamine and sulfur light are used in low-temperature inert solution, methyl thiocyanate can be obtained. The efficiency of this method is high, but due to the toxicity of sulfur light, the operator and the environment are very large, so the use of sulfur needs to be cautious.
