General description

Boron trifluoride is a colourless gas which readily reacts with water to form hydrates. It has been widely used as catalyst for polymerizations, alkylations and condensation reactions. It is used as gas flux for internal soldering or brazing. It also finds application in being used as extinguisher for magnesium fires. Furthermore esterification by BF3-butanol helps in obtaining volatile derivatives of aliphatic acids such as hydroxyacids.

Application

It was used in extraction and derivatization of γ−hydroxybutyrate from human plasma or urine during a study to determine 1,4-butanediol and γ-hydroxybutyrate using capillary gas chromatography.

Other Notes

Reagent for butyl esters and trifluoroacetyl.
