Scope

1.1 This test method covers the determination of sulfur in aromatic hydrocarbons, their derivatives and related chemical having typical sulfur concentrations from 0.005 to 10 mg/kg.

1.2 This test method may be extended to higher concentrations by dilution.

1.3 This test method is applicable to aromatic hydrocarbons such as benzene, toluene, cumene, p-xylene, o-xylene, cyclohexane, phenol, cresols, xylenols, and other aromatic or oxygenated aromatic compounds.

1.4 The following applies to all specified limits in this test method: for purposes of determining conformance with this standard, an observed value or a calculated value shall be rounded off to the nearest unit in the last right-hand digit used for expressing the specification limit in accordance with the rounding-off method of Practice E 29.

1.5 This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. specific precautionary statements are given in 7./5, 76. 8, 11.4.

Significance and Use

Sulfur can be a catalyst poison in the aromatic chemical manufacturing process. This test method can be used to monitor the amount of sulfur in aromatic hydrocarbons. This test method may also be used as a quality control tool and in setting specifications for sulfur determination in finished products.
