Description

General description

Boron trifluoride-methanol (BF-M) is an esterification reagent. BF-M is a powerful acidic catalyst for the esterification of the fatty acids. It easily cleaves acetylated dyes resulting in free amino groups. BF-M catalyzed trans esterification of vegetable oils forms biodiesel.

Application

Used in the deactylation of acetanilides.It is also used to study the synthesis of amino group containing cyanine dyes of different types and to prepare fatty acid methyl esters.
