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 device 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).

Highlights

Bromine Titrator

The Bromine Titrator consists of

  • an automatic volumetric titrator with potentiometric pH indication
  • a titration vessel with stirrer unit


The determination of of Bromine Index or Bromine Number is based on

  • a potentiometric titration in an anhydrous medium
  • a precise indication by a double platinum electrode, which is stable over long periods

The standard solutions and the samples must be titrated at 0 - 5 °C.

Steps of the analysis are

  1. Determination of the blank value
  2. Standardization of the titration solution
  3. Titration of oil samples

Advantages

  • 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
