Antimony Trifluoride

Antimony trifluoride is a chemical compound with the formula SbF3. It is a white crystalline solid that is highly soluble in water and other polar solvents. Antimony trifluoride has a trigonal bipyramidal molecular geometry, with three fluorine atoms occupying equatorial positions and two lone pairs of electrons located in the axial positions.

Antimony trifluoride is commonly used as a catalyst in the production of polyethylene terephthalate (PET), which is a type of plastic used in a variety of applications such as bottles, clothing fibers, and food packaging. The compound acts as a nucleating agent, helping to promote the formation of the desired crystal structure in the PET during polymerization.

Antimony trifluoride is also used in the production of certain types of glass, such as optical glass and fiberglass, where it serves as a refining agent to help remove impurities from the glass.

In terms of safety, antimony trifluoride can be toxic when ingested or inhaled, and it can cause skin and eye irritation upon contact. It is important to handle the compound with care and wear appropriate protective equipment when working with it.
