| Bromine Number of Petroleum Distillates |
| Log #67B Titration Application Note |
| The bromine number of a sample is the number of grams of bromine that will react with 100 g of sample. The bromine number titration is used to indicate the level of (olefinic) unsaturated in petroleum distillates. Under the right condition, bromine reacts more or less stoichiometrically with the double bond. In the example given here, bromine number of cyclohexen, the sample is weighed into a beaker containing an acidic solvent and titrated with an aqueous solution of potassium bromide/bromate. |
