A new method of bromine number determination appropriate to heavy-ends petroleum is reported. This method, which uses an electrochemical titration and tetrabutylammonium tribromide as reagent, has been tested on Boscan atmospheric residues. The titration of the unreacted tribromide ions and of the bromide ions produced enables the proportion of the bromine addition to multiple bonds and the proportion of substitution reactions with aromatic compounds (phenols, amines, etc.) to be estimated. The sensitivity and reproducibility of this easy method are both good.
