Boron fluoride diethyl etherate storage conditions

Boron fluoride diethyl ether compounds are active in nature, and when stored, the following rules should be followed.

First, it should be stored in a cold and dry place. If you cover it with fear of heat and dampness, heat may cause its reaction to intensify, and dampness is easy to contact with water and change. If you are in a high temperature environment, its chemical activity rises sharply, or it may lead to unexpected risks; when exposed to water, it may cause severe reactions, damage its quality and produce harmful things. Therefore, the temperature of the storage should be controlled at a moderately low level, and the air should be dry to prevent moisture from invading.

Second, you must avoid open fires and hot topics. When this compound encounters an open flame or hot topic, there is a risk of ignition and explosion. Due to its chemical structure, it is easy to cause a chain reaction near the fire source and heat, and eventually cause the disaster of ignition and explosion. It is around the storage area, and fireworks are strictly prohibited, and the heating device should also be far away to ensure its safety.

Furthermore, the choice of storage device is crucial. It is appropriate to use a corrosion-resistant and well-sealed device. Boron fluoride diethyl ether compound is corrosive, and ordinary devices are easily eroded by it, causing leakage. If the seal is good, it can prevent it from contacting with outside air and moisture to ensure its stability. If it is stored in a special glassware or a specific plastic container, it should be sealed with a lid to prevent it from leaking and maintain its quality.

In addition, the storage should be well ventilated. If it leaks, good ventilation can quickly disperse the harmful atmosphere, reduce its concentration in the air, and reduce the risk of not erupting. And ventilation can make the gas in the storage fresh, avoiding gas accumulation and risk.

Repeat, the storage should be kept away from incompatible things. Such as strong oxidants, strong bases, etc., will play a role in encountering them. Strong oxidants can promote oxidation, and strong bases can break their chemical structure, which can cause changes in quality and risk. Therefore, when storing, it is necessary to carefully observe the things stored around, isolate those that are incompatible, and ensure their safety.

In short, the storage of boron fluoride diethyl ether compounds is related to safety and quality, and it is necessary to follow the above words to have no worries.

Boron fluoride diethyl etherate in the use of what are the precautions

During the use of borofluorodiethyl ether, many things need to be paid attention to. This agent is toxic and corrosive, and can cause burns when it touches the human body. If it is accidentally inhaled or ingested, it will be even more harmful. Therefore, when using it, be sure to be fully armed, wear protective clothing, protective gloves and goggles, and beware of the agent coming into contact with the skin and eyes. The operation should be carried out in a well-ventilated place, preferably in a fume hood, which can effectively disperse volatile gases and avoid inhalation.

Furthermore, borofluorodiethyl ether is sensitive to water and reacts easily in contact with water. When storing, it should be placed in a dry place to prevent water vapor from invading. The access process should be quick, and it should be sealed immediately after use to prevent moisture and deterioration. The utensils used during use must also be dry and water-free.

In addition, boron fluorodiethyl ether has high chemical activity and is easy to react with a variety of substances. When using, be careful not to mix with strong oxidants, strong bases and other substances, otherwise it may cause violent reactions and even explosions. Before use, you should fully understand its compatibility with other chemical substances used, strictly follow the operating procedures, and do not mix chemicals with unknown characteristics at will.

At the same time, after use, the remaining chemicals and waste should be properly disposed of. Do not dump at will, and should be handled by professional institutions in accordance with relevant regulations to prevent pollution of the environment. If any chemicals are spilled during use, appropriate measures should be taken immediately to clean up and avoid diffusion.

Boron fluoride diethyl etherate what is the preparation method

The preparation method of boron fluoride diethyl ether complex is as follows:

First, the raw materials need to be prepared. Boron sources are commonly used such as borax, boric acid, etc. Fluoride can be selected from hydrogen fluoride, potassium fluoride, etc. Diethyl ether is the solvent and ligand required for the reaction.

In a suitable reaction vessel, mix the boron source with an appropriate amount of fluoride. If the boron source is boric acid, the fluoride is hydrogen fluoride, and the reaction is carried out in the presence of diethyl ether. This reaction needs to be controlled by temperature, and it is usually maintained at a low temperature, such as 0-10 ° C. If the temperature is too high, it may cause the reaction to be too violent and form impurities. When

reacts, boric acid and hydrogen fluoride react chemically in the environment of diethyl ether. The boron atoms of boric acid interact with fluoride ions and diethyl ether molecules to form boron fluoride diethyl ether complexes.

After the reaction is completed, the product needs to be separated and purified. Generally, unreacted solid impurities are removed by means of filtration. Later, by distillation, because the boiling point of diethyl ether is relatively low, diethyl ether can be evaporated first, and the remaining substances can be further recrystallized to obtain pure boron fluoride diethyl ether complexes.

During the operation, it is necessary to strictly abide by safety procedures. Due to the corrosive and toxic nature of hydrogen fluoride, it is necessary to operate in a well-ventilated environment and take protective measures to ensure the safety of the operator and the smooth progress of the reaction.
