Determination of Bromine Index or Bromine Number of hydrocarbons

The value of Bromine Index or Bromine Number expresses the trace amount of unsaturated constituents of hydrocarbons and oils. It is determined by measuring of consumed bromine for cleavage of double or multiple bounds during the titration. The value are needed for determination of parameters for further processing of petroleum products.

The Titramax VT BROMINE is conform to standards ASTM D 1159, ASTM D 2710 and ASTM D 5776.

The measurement uses a potentiometric titration method in an anhydrous medium. The titration with titrant starts, once the sample is dosed into the reagent. The user has to enter the sample weight into the menu. The titration is performed automatically until the endpoint indication of measurement.

At the end of the measurement, results are shown in mg Br2/100 g (Bromine Index) or g Br2/100 g (Bromine Number).


The device is suitable for analysis of

  • petroleum distillates
  • gasoline (including leaded, unleaded, oxygenated fuels)
  • kerosine
  • distillates in the gas oil range
  • commercial propylene trimer and tetramer
  • butene dimer
  • mixed nonenes, octenes, heptenes
  • olefinfree hydrocarbons or mixtures


  • Complete measuring system for the determination of of Bromine Index or Bromine Number
  • Fully-automatic volumetric titration
  • Precise adjustment of the titration parameters by control algorithms
  • Preset measurement method allows an immediate start
  • The result output can be adjusted to your needs by using a formula generator
