What are the precautions for storing diethyl ether-boron trifluoride?
Diethyl ether and boron trichloride should pay attention to many matters when storing. Diethyl ether is volatile and flammable, and its steam can form an explosive mixture with air, which is easy to burn and explode in case of open flame and hot topic. When storing, be sure to store in a cool and well-ventilated place, away from fire and heat sources, and the storage temperature should not exceed 26 ° C. At the same time, it should be stored separately from oxidants, acids, alkali metals, etc., and should not be mixed.
Triboron chloride will react violently in contact with water to produce toxic gases such as hydrogen chloride. Therefore, it needs to be stored in a dry and ventilated warehouse, away from fire and heat sources, and the storage temperature should be maintained below 25 ° C. It should also be stored separately from alkalis and alcohols, and cannot be mixed. Due to its strong corrosiveness, the storage container must be corrosion-resistant and well sealed to prevent leakage from causing danger.
The place where diethyl ether and boron trichloride are stored needs to be equipped with corresponding varieties and quantities of fire-fighting equipment and leakage emergency treatment equipment. For diethyl ether, because steam is heavier than air, it can spread to a considerable distance at a lower place. In case of fire, it will catch fire and backfire. Therefore, the storage area should pay attention to ventilation and ventilation to prevent steam accumulation. Once boron trichloride leaks, the hydrogen chloride gas produced by it is highly irritating and corrosive to the human respiratory tract, eyes, etc. Therefore, protective equipment and emergency treatment devices should be prepared at the storage place to deal with possible leakage conditions in time. Overall, when storing diethyl ether and boron trichloride, care must be taken from environmental conditions to item isolation and safety measures to ensure the safety of the storage process.
What are the chemical properties of diethyl ether-boron trifluoride?
Diethyl ether and boron trichloride are both common substances in chemistry, each with unique chemical properties.
Diethyl ether, a colorless, flammable, and odorless liquid at room temperature and pressure. Its boiling point is about 34.6 ° C, and the relative density is small, only 0.7134. This substance is slightly soluble in water, but it can be miscible with most organic solvents such as ethanol and acetone. Diethyl ether is relatively stable in chemical properties, but it can also participate in many chemical reactions under certain conditions. If it encounters strong acids, it can form a salt; when exposed to air for a long time, it will slowly oxidize and form a peroxide. When this peroxide is heated or impacted, it is very easy to cause an explosion. Therefore, when using and storing diethyl ether, be careful.
Boron trichloride is a colorless fuming liquid or gas under normal conditions, with a pungent odor. Melting point -107.3 ° C, boiling point 12.5 ° C. It will react violently in contact with water to produce hydrogen chloride gas, so it will form white smoke in humid air. Boron trichloride is a typical Lewis acid, which can be added to Lewis bases. In the field of organic synthesis, it is often used as a catalyst to assist in the progress of many organic reactions, such as the Fu-G reaction.
Compared with the two, diethyl ether exhibits more characteristics of organic solvents and has relatively mild chemical properties; while boron trichloride plays a more active role in chemical reactions due to its strong Lewis acidity and violent reaction in contact with water. In practical applications, it is necessary to follow the operating procedures strictly according to its chemical properties, and use and store it properly.
What are the potential hazards of diethyl ether-boron trifluoride to human health?
Dioxin and trichloroethylene are both harmful chemicals that pose many potential hazards to human health.
Dioxin is a type of persistent organic pollutant that is highly toxic. It is extremely difficult to degrade in the environment and can be enriched through the food chain. If the human body is exposed to dioxin, it will bear the brunt of the harm to the immune system, reduce immune function, and make the human body more susceptible to disease. In addition, it also has serious effects on the reproductive system, or cause reproductive dysfunction, fetal development abnormalities, such as an increase in the birth rate of deformed children. Long-term exposure to dioxin also significantly increases the risk of cancer, especially lung cancer and skin cancer.
Trichloroethylene is a volatile organic solvent. If inhaled or exposed to skin, trichloroethylene can easily irritate the respiratory tract and skin. In mild cases, it can cause cough, asthma, itchy skin, erythema and other symptoms; in severe cases, it can cause severe diseases such as chemical pneumonia and exfoliative dermatitis. Long-term exposure to trichloroethylene can also damage the nervous system, causing dizziness, headache, fatigue, memory loss and other neurasthenia-like symptoms. In severe cases, it can cause coma and convulsion. It also has adverse effects on organs such as the liver and kidneys, interfering with the normal operation of liver and kidney functions.
In summary, dioxin and trichloroethylene are extremely harmful to human health. We should try our best to avoid contact with them in production and life, and take protective measures to ensure human health.
What are the safety measures for diethyl ether-boron trifluoride during use?
Diacetonitrile-boron trichloride is also a chemical substance. During its use, safety protection measures are of paramount importance.
The first to bear the brunt is related to personnel protection. Operators must wear special protective clothing, which is made of chemical-resistant materials, which can effectively resist the damage of diacetonitrile-boron trichloride to the body. Protective gloves are also required. The material of the gloves is tough and has good corrosion resistance to ensure the integrity of the hands. Face protection is also indispensable. The protective mask can block the liquid that may be splashed, and the goggles focus on eye protection to prevent the evaporation of aerosols from irritating or damaging the eyes.
Furthermore, ventilation facilities are extremely critical. In the place of use, a strong ventilation device must be prepared to ensure smooth air. In this way, the harmful gases volatilized by diacetonitrile-boron trichloride can be dispersed in time, and the concentration in the air can be reduced to avoid the risk of poisoning caused by its accumulation. This ventilation device should be regularly overhauled to maintain its effectiveness.
In addition, storage is also exquisite. Diacetonitrile-boron trichloride should be stored in a cool, dry and well-ventilated place. Keep away from fire and heat sources, because both are flammable and explosive. And it should be stored separately from oxidants and acids, and should not be mixed to prevent violent chemical reactions. The storage area should be equipped with leakage emergency treatment equipment and suitable containment materials.
During use, be sure to operate with caution. Strictly follow the operating procedures and do not slack at all. If there is a leak, immediately start the emergency plan, evacuate the surrounding personnel, isolate the leakage area, and then use appropriate treatment methods according to the size of the leak, or absorb it with inert materials such as sand, or rinse and dilute it with a lot of water.
