Cylinder Gas China Factory High Purity manufacture semiconductors gas Boron trichloride

Product Description

Boron trichloride (BCl3) is a chemical compound composed of one boron atom and three chlorine atoms. It is a colorless gas with a pungent odor. BCl3 is known for its Lewis acidity, meaning it readily accepts electron pairs from other molecules or ions. Here are some key points about BCl3:

1. Chemical Formula: BCl3
2. Molecular Weight: 117.17 g/mol
3. Physical Properties: Boron trichloride is a gas at room temperature and atmospheric pressure. It has a boiling point of -107.8 degrees Celsius (-162.0 degrees Fahrenheit) and a melting point of -107.8 degrees Celsius (-162.0 degrees Fahrenheit).
4. Odor: BCl3 has a sharp and irritating odor.
5. Lewis Acidity: BCl3 is a Lewis acid, meaning it can accept an electron pair from a Lewis base to form a coordinate covalent bond.
6. Reactivity: Boron trichloride reacts with water to form boric acid (H3BO3) and hydrochloric acid (HCl).
   BCl3 + 3H2O → H3BO3 + 3HCl
   It also reacts with alcohols to form alkyl chlorides:
   BCl3 + 3ROH → B(OR)3 + 3HCl
7. Uses: BCl3 is primarily used as a reagent in organic synthesis, particularly in the production of boron compounds. It is also utilized in the manufacture of semiconductors and as a catalyst in various chemical reactions.
8. Safety Precautions: Boron trichloride is a toxic and corrosive substance. It can cause severe burns and eye damage upon contact. Proper safety measures, including the use of protective equipment, should be followed when working with BCl3.
