Electronic Grade 6n Boron Trichloride BCL3 Gas 50kg Per Cylinder

Boron trichloride, also known as BCl3, is a chemical compound composed of one boron atom and three chlorine atoms. It is a colorless, toxic gas with a pungent odor. BCl3 is commonly used in various industrial applications, primarily as a reagent and catalyst in organic synthesis.

Here are some key points about BCl3:

1. Structure: BCl3 has a trigonal planar molecular geometry, with the boron atom at the center and the three chlorine atoms surrounding it. The molecule has a total of 24 valence electrons.

2. Preparation: Boron trichloride can be prepared by reacting boron oxide (B2O3) or boron carbide (B4C) with chlorine gas (Cl2).

3. Physical properties: BCl3 is a gas at room temperature and atmospheric pressure. It has a boiling point of -107.8 degrees Celsius (-162 degrees Fahrenheit) and a melting point of -107.8 degrees Celsius (-162 degrees Fahrenheit).

4. Chemical properties: BCl3 is highly reactive due to the presence of the empty p-orbital on the boron atom. It readily reacts with various nucleophiles and Lewis bases. For example, it reacts with water to form boric acid (H3BO3) and hydrochloric acid (HCl).

5. Uses: BCl3 is primarily used as a reagent and catalyst in organic synthesis. It can be used to introduce the boron atom into organic molecules, such as in the formation of boronic acids. It is also employed in the production of boron-doped semiconductors, as a component of plasma etching gases in the semiconductor industry, and as a fluorine source in the manufacturing of fluorocarbons.

6. Safety considerations: Boron trichloride is toxic and corrosive. It can cause severe burns upon contact with the skin, eyes, or respiratory system. Proper safety precautions, such as the use of protective equipment and working in a well-ventilated area, should be followed when handling BCl3.
