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. 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).
