ASTM-D2710 › Standard Test Method for Bromine Index of Petroleum Hydrocarbons by Electrometric Titration
The following bibliographic material is provided to assist you with your purchasing decision:
Scope
1.1 This test method covers the determination of the amount of bromine-reactive material in petroleum hydrocarbons and is thus a measure of trace amounts of unsaturates in these materials. It is applicable to materials having bromine indexes below 1000.
1.2 This test method is applicable only to essentially olefin-free hydrocarbons or mixtures that are substantially free from material lighter than isobutane and have a distillation end point under 288 °C (550 °F).
Note 1: This procedure has been cooperatively tested on materials with bromine indexes in the range from 100 to 1000. These materials include petroleum distillates such as straight-run and hydrocracked naphtha, reformer feed, kerosine, and aviation turbine fuel.
Note 2: Materials with bromine index greater than 1000 should be tested for bromine number using Test Method D1159/IP 130.
Note 3: Bromine index of industrial aromatic hydrocarbons should be determined using Test Method D1492 or D5776. The subcommittee is currently examining ways to achieve more consistent end point values.
1.3 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
Significance and Use
5.1 This test method provides a measure of trace amounts of unsaturated hydrocarbons in petroleum distillates boiling up to 288 °C (550 °F). An estimate of the quantity of these materials is useful in assessing the suitability of the lighter fractions for use as reaction solvents.
