Ethylpentane
Content introduction
1、 Product introduction
Ethyborane is a simple borane that can be separated at present. It is a colorless gas at room temperature and can form an explosive mixture with air
Spontaneous combustion in gas. It is highly toxic. Ethyborane has high chemical activity and is easy to react with various inorganic and organic molecules. This is not only because Ethyborane generates
The heat formation is positive (i.e. endothermic compound), and boron has great affinity for elements with strong electronegativity, such as fluorine, oxygen, nitrogen and phosphorus. At room temperature, ethane borane
Hydrogen and high grade borane are produced by hydrolysis. When the temperature exceeds 300 ℃, ethane is decomposed into boron and hydrogen. Ethylene borane products are usually diluted with nitrogen, argon, helium or hydrogen.

2、 Application of Ethylene Borane
High-energy fuels for rockets and missiles, metal welding, pharmaceutical and spice industries, reducing agents in organic synthesis, catalysts for olefin polymerization, rubber vulcanizing agents
Borohydride intermediate, diffusion and oxidation in semiconductor manufacturing, epitaxial growth, chemical vapor deposition.
3、 Precautions
Store in a cool and ventilated warehouse. Keep away from kindling and heat source. The warehouse temperature should not exceed 50 ℃; It shall be stored separately from combustible materials and oxidants
Mixed storage. The storage area shall be equipped with leakage emergency treatment equipment. The operators must be specially trained and strictly abide by the operating procedures. Do not expose to the sun, throw heavily, or hit
It is prohibited to bake gas cylinders with open fire and rough loading and unloading. There is a cylinder inspection time on the bottle neck of the cylinder, and the unqualified cylinder shall be entrusted to Philips special gas suppliers
The qualified pressure vessel inspection unit shall conduct inspection. It is strictly prohibited to use expired cylinders.
4、 Leakage emergency treatment
Evacuate the personnel in the contaminated area quickly and isolate them immediately. In case of small leakage, isolate them for 300 meters, and in case of large leakage, isolate them for 450 meters. Strictly control the access of * * *.
Cut off the ignition source. It is recommended that emergency treatment personnel wear self-contained positive pressure respirators and gas protective clothing. Enter the site from the upwind. Cut off the source of leakage as much as possible. Reasonable ventilation, plus
Fast diffusion. Dilute with spray like water. Leaking containers shall be properly treated and reused after repair and inspection.
5、 First aid measures
Inhalation: quickly leave the site to a place with fresh air. Keep the respiratory tract unobstructed. If breathing is difficult, give oxygen. If breathing stops, perform artificial respiration immediately. Get medical attention.
Fire extinguishing method: cut off the air source. If the gas source cannot be cut off immediately, it is not allowed to extinguish the burning gas. Spray water to cool the container, and move the container from the fire site if possible
To an open place. Fire extinguishing agent: carbon dioxide. Disable water column and foam.
