Dichloroethane is a genus of halogenated hydrocarbons. It is a colorless or light yellow transparent liquid at room temperature and pressure. It has a chloroform-like odor and a sweet taste. Its physical properties are quite interesting, so let me tell you one by one.
Looking at its properties, dichloroethane is a liquid, which makes it easy to operate in many chemical reactions and industrial processes. Its boiling point is about 83.5 ° C. This boiling point allows it to be easily converted into a gaseous state under appropriate heating conditions, which is convenient for distillation, separation and other operations.
Furthermore, the density of dichloroethane is greater than that of water, which is about 1.26g/cm ³. This property causes it to sink to the bottom when mixed with water, and it can be separated from the water phase by means of liquid separation.
The solubility of dichloroethane is also worth mentioning. It is slightly soluble in water, but it can be miscible with organic solvents such as ethanol, ether, and chloroform. Such solubility makes it an excellent organic solvent, which is widely used in coatings, adhesives, inks, and other industries. It can dissolve many organic substances and assist in meeting specific process requirements.
In addition, dichloroethane is highly volatile and volatile in the air to form a vapor. Its vapor is heavier than air and can spread at a lower place to a considerable distance. In case of ignition, it will catch fire and backfire. When using and storing, it is necessary to pay full attention to its volatility and flammability, and take appropriate fire and explosion-proof measures.
In summary, the physical properties of dichloroethane, such as its liquid state, specific boiling point, density, solubility, and volatility, determine its use and application in industrial and scientific research fields. Safety precautions should also be taken during use.

Dichloroethane is also a chemical substance. Its chemical properties are stable in ordinary environments. However, in case of open flames or hot topics, it will cause disasters, can burn violently, and even explode, which cannot be ignored.
Dichloroethane is volatile and can form an explosive mixed gas in the air. It encounters with oxidants and is prone to chemical reactions, which are all dangerous omens. And this substance can react with many metals, especially when there is moisture, it changes faster.
Under light, dichloroethane may slowly decompose, giving rise to harmful substances such as hydrogen chloride. And because its steam is heavier than air, it can spread far at a lower place, and it will ignite in case of a fire source, so the fire will spread.
Dichloroethane can be stable under general storage conditions without the above adverse factors. However, in the chemical industry, the subtleties are also related to safety, so we must be cautious, take precautions, and strictly abide by the rules of its storage and use to ensure safety. Therefore, although its chemical properties seem to be stable under normal circumstances, the potential risks are inevitable. Under many variables, it may change and cause people to be in danger.

The method of making ethylene dioxide has existed in ancient times, and each method has its own length. Today, it is described in ancient methods for exploration.
One is the addition of ethylene and chlorine. This is a classic method. Ethylene meets chlorine, like a boat meets the wind, and combines with the trend. The text says: "Ethylene is mixed in chlorine, and the two are combined to form dichloroethane." In this process, ethylene ($C_2H_4 $) and chlorine ($Cl_2 $) are mixed in a gas phase, at room temperature and pressure or under a little pressure, according to the following formula: $C_2H_4 + Cl_2\ longrightarrow C_2H_4Cl_2 $. The resulting product is refined by fractionation and other methods to obtain pure ethylene dichloride. In this way, the raw materials are easy to obtain and the reaction is easier to control. However, chlorine is highly corrosive and requires high equipment.
Second, the reaction method of ethanol and hydrogen chloride. The ancients said: "Alcohol and hydrochloric acid are combined, and halogenated hydrocarbons are obtained by heating." Ethanol ($C_2H_5OH $) and hydrogen chloride ($HCl $) react when heated to a suitable temperature under the action of a catalyst such as sulfuric acid. The formula is: $C_2H_5OH + HCl\ stackrel {catalyst} {\ longrightarrow} C_2H_5Cl + H_2O $. The generated chloroethane is purified by distillation and other steps. In this way, the raw materials are also common, but the reaction rate is slightly slower, and attention should be paid to the amount of catalyst and recovery. < Br >
Third, ethane and chlorine substitution method. "When alkanes encounter chlorine, light will replace them." Ethane ($C_2H_6 $) and chlorine ($Cl_2 $) under light or heating conditions, chlorine atoms replace hydrogen atoms in ethane, and chloroethane can be obtained. The reaction is complicated, such as $C_2H_6 + Cl_2\ stackrel {light} {\ longrightarrow} C_2H_5Cl + HCl $, and it will be accompanied by polychlorinated substitutes. This process, although the raw materials are cheap, the products are complex and difficult to separate, requiring fine processes to improve purity.

Dioxyethane, during storage and transportation, everyone should pay attention to it.
First, fire and explosion-proof is essential. Dioxyethane is extremely flammable, and in case of open flames, hot topics or contact with oxidants, there is a risk of combustion and explosion. Therefore, the storage place should be a cool and ventilated place, away from fire and heat sources, and the storage temperature should not exceed 30 ° C. And its vapor is heavier than air and can spread to a considerable distance at a lower place. In case of fire source, it will catch fire and backfire. When transporting, the vehicle used must be equipped with the corresponding variety and quantity of fire-fighting equipment and leakage emergency treatment equipment.
Second, leakage prevention is also critical. This substance is volatile. If it leaks, it will not only pollute the environment, but also cause the danger of explosion. The storage container must be well sealed and its integrity should be checked regularly. During transportation, ensure that the container does not tip, leak or damage. In case of accidental leakage, personnel from the leakage contaminated area should be quickly evacuated to a safe area and quarantined, and access should be strictly restricted. Emergency personnel must wear self-contained positive pressure breathing apparatus and fire protective clothing. Cut off the source of leakage as much as possible to prevent entry into restricted spaces such as sewers and flood drains.
Third, the protection of the human body should not be ignored. Dioxyethane has irritating effects on the eyes and respiratory tract. Inhalation can cause pulmonary edema, and exposure can cause dermatitis. Storage and transportation personnel should be equipped with appropriate protective equipment, such as gas masks, protective gloves, protective glasses, etc., to ensure their own safety.
Fourth, follow regulations and standards. Storage and transportation of dioxyethane must strictly follow relevant national laws, regulations and standards, and go through necessary permits and procedures to ensure legal compliance throughout the process. In this way, the storage and transportation of dioxethane can be kept safe.
