First, product introduction
Borane is the simplest borane that can be separated at present. It is a colorless gas at room temperature. It can form an explosive mixture with air, and it is wet in the air.
Spontaneous combustion in gas. It's very poisonous. Borane has a high chemical activity, which is easy to react with various inorganic and organic molecules, not only because of the borane of borane.
Heat is positive (i.e., the endothermic compound) boron has a great affinity for the element fluorine, oxygen, nitrogen, phosphorus and other negative strong. At room temperature, borane
The solution produces hydrogen and high grade borane, and the borane is decomposed into boron and hydrogen at more than 300 degrees C. Borane products are usually diluted with nitrogen, argon, helium, or hydrogen.

Two, the application of borane
Rocket and missile's high-energy fuel, metal welding, pharmaceutical and perfume industry, reductant in organic synthesis, catalyst for olefin polymerization, rubber vulcanizing agent.
The intermediates of borohydride, diffusion and oxidation, epitaxial growth and chemical vapor deposition in semiconductor manufacturing.
Five. Precautions
Store in a cool, ventilated storeroom. Stay away from fire and heat. The temperature of the storeroom should not exceed 50 degrees centigrade; it should be kept separately from the inflammable and oxidizing agent.
Mixed storage. The storage area should be equipped with leakage emergency treatment equipment. The operator must undergo special training and strictly abide by the operating rules. Do not explode, do not toss, do not impact, strict
It is forbidden to roast gas cylinders with fire, and barbarous loading and unloading is strictly prohibited. A steel bottle cylinder inspection time, does not meet the requirements of special gas cylinders shall be entrusted to the supplier ferrill etc.
The qualified pressure vessel inspection unit is tested. The use of overdue steel bottles is strictly prohibited.
Six. Leakage of emergency treatment
Quickly evacuate the spill pollution area personnel first wind, and immediately carry out isolation, small leakage of 300 meters, large leakage of 450 meters in isolation, strict restrictions on access.
Cut off the fire source. It is suggested that the emergency treatment personnel wear self-contained positive pressure respirator and wear antivirus clothes. Enter the scene from the upper wind. Cut off the leakage source as much as possible. Reasonable ventilation, add
Velocity diffusion. Spray water dilute. The gas leakage container should be properly treated, repaired and reused after inspection.
Seven, first aid measures
Inhalation: quickly out of the scene to the fresh air. Keep the respiratory tract unobstructed. If breathing is difficult, give oxygen. If breathing is stopped, artificial respiration is carried out immediately. Go to a doctor.
Fire extinguishing method: cut off the gas source. If the gas source can not be cut off immediately, it is not allowed to extinguish the burning gas. Water spray cooling container, if possible to move the container from the fire.
To the open space. Fire extinguishing agent: carbon dioxide. Disable water column and foam.
