Use of tetrabutylammonium tribromide for voltametric titration of unsaturation in vegetable oils and fatty acids

The use of tetrabutylammonium tribromide as reagent for bromination of carbon‐carbon double bonds of fatty acids and vegetable oils, followed by a voltametric titration of tribromide and bromide ions, has been studied. This method is easy and fast, and results show good accuracy and high sensitivity...
