Description

General description

Boron trifluoride (BF3) is a Lewis acid; it is a very useful reagent for forming esters from acids. Boron trifluoride is commercially available as a 14% solution in methanol for forming esters derivatives. It catalysed reactions carried out in a water bath are very rapid and can be completed in a few minutes.[1] Boron-trifluoride-catalysed transesterification of vegetable oils is one of the most popular methods. For transesterification of vegetable oils, BF3 is used in methanol (15 to 20% w/v).[2]

Application

Learn more in the Product Information

Boron trifluoride-methanol solution may be used for catalysing a method, used for the synthesis of bishydroperoxides and their derivatives, based on a reaction of ketals with a solution of hydrogen peroxide in anhydrous ether.[3] It may also be used for the rapid preparation of fatty acid esters for gas chromatographic analysis, as it converts fatty acids to their respective methyl esters in about 2 minutes.[4]

Suitable for derivatization of hydroxy fatty acids.
