ASTM UOP744 : 2006

Defines a method for determining individual C[6] through C[10] aromatic compounds in petroleum distillates or aromatic concentrates having a final boiling point of 210 degree C or lower.

This method is for determining individual C₆ through C₁₀ aromatic compounds in petroleum distillates or aromatic concentrates having a final boiling point of 210°C or lower. C₁₁ and heavier aromatics are reported as a group. C₁₀ and heavier non-aromatics may interfere with the determination of benzene and toluene. When this occurs, benzene and toluene can be determined by ASTM Methods D 5443, D 5580, D6729, or D 6839, or UOP Methods 690, or 870. Other applications for this method include the assay of any C₁₀ or lower boiling aromatics, such as benzene, toluene, mixed xylenes, etc. This method may also be used to provide a distribution of C₈ aromatics and/or C₉ and heavier aromatics to a value determined by a different method. When used for any of the above applications, the quantitation limit for a single aromatic component is 0.01 mass-%.
