What are the storage conditions for Boron Trifluoride Acetonitrile Complex?
Boron trifluoride acetonitrile, complexes, are sensitive and need to be stored with caution. This complex is lively, and when it is stored, the first thing to do is to keep the environment dry and clean. It should be placed in a shady and dry place to avoid direct sunlight. If exposed to light, it may change its properties and cause the quality to not exist.
In addition, it is very sensitive to moisture, and the invasion of moisture is easy to cause its reaction. Therefore, when storing moisture, it can be supplemented by a desiccant to keep the environment dry.
Furthermore, temperature control is also necessary. It is suitable for room temperature, but it cannot be near heat. Heat accelerates its reaction or causes decomposition. If it is hot in the summer, special attention should be paid, or it needs to be protected with a temperature-controlled device.
Hidden devices are also critical. Choose a corrosion-resistant device, such as glass or specific plastic devices, to prevent it from interacting with the wall and damaging its quality. And the device must be sealed to avoid air connection with the outside.
When hiding, it is necessary to isolate the source of fire and explosion. Because of its sexual activity, it is dangerous to encounter fire or explosives.
The hiding place should be well-aware, marked with its characteristics, harm and emergency measures, so that it can be used and prevented. In this way, the quality of the boron trifluoride acetonitrile and the complex can be preserved, so that it can be used when needed.
Boron Trifluoride Acetonitrile Complex
The common methods for preparing boron trifluoride acetonitrile complexes are as follows.
First, the reaction of boron compound with boron trifluoride is carried out in acetonitrile solvent. Take an appropriate amount of boron source, such as boric acid or borax, place it in the reactor, and add a sufficient amount of acetonitrile as the reaction medium to create a suitable reaction environment. Then, slowly introduce boron trifluoride gas. During this process, the reaction temperature and gas entry rate must be strictly controlled. If the temperature is too high, the reaction is easy to get out of control; if the rate is too fast, it is not conducive to the full reaction. In general, the temperature should be maintained at a low range, about 0-20 degrees Celsius, and the stirring should be continued to promote the full contact of the reactants, and then the boron trifluoride acetonitrile complex is formed.
Second, the metal boride is reacted with boron trifluoride in the acetonitrile system. Select the appropriate metal boride, such as magnesium boride, and put it into the reaction vessel containing acetonitrile. Then, according to the specific ratio and rate, add the boron trifluoride reagent. In this reaction, the activity of the metal boride, the amount of boron trifluoride, and the reaction conditions, such as temperature and time, all have a significant impact on the formation of the product. The reaction temperature may be slightly adjusted, controlled at 10-30 degrees Celsius, and the reaction time also depends on the specific situation, ranging from several hours to ten hours. After this step, the target complex can be obtained.
Third, use an organic boron reagent to react with boron trifluoride in an acetonitrile environment. Select a suitable organic boron reagent, such as some alkyl boron compounds. Dissolve the organic boron reagent in acetonitrile to form a uniform solution, and then slowly add boron trifluoride to it. This reaction requires a high purity of the reaction system, and impurities may affect the reaction process and product purity. During the reaction, it is also necessary to precisely control the temperature, reaction time and other factors. The temperature may be between 15 and 35 degrees Celsius, and the reaction elements can be finely regulated to successfully prepare boron trifluoride acetonitrile complexes.
What are the safety precautions for Boron Trifluoride Acetonitrile Complex?
The safety precautions for boron trifluoride acetonitrile complexes are quite important. This substance is corrosive and will cause damage to the skin and eyes when it touches. When using it, protective equipment, such as gloves, goggles, protective clothing, etc., must be strictly worn to avoid direct contact with it.
It may be volatile in the air, so the place where it is used must be well ventilated to prevent inhalation of its vapor and damage to the respiratory system. And this complex may react violently with other substances. When using it, review its chemical properties carefully and avoid mixing with contraindicated substances.
Also, when storing, it should be placed in a cool, dry and ventilated place, away from fire and heat sources, to prevent it from deteriorating or causing danger. When taking it, take it according to the exact amount, not too much, and store it properly after use, so as not to change with air, moisture, etc.
In addition, if you unfortunately touch it or inhale it, you should quickly apply first aid. If you touch the skin, rinse it with a lot of water immediately, and then seek medical attention; if you enter the eye, you should also quickly buffer it with water, and seek medical attention immediately. Those who inhale, quickly move to a fresh air place, if you feel unwell, call for medical assistance. All use of this thing should be done with caution, and follow safety regulations to ensure safety.
