ASTM D5194 – Standard Test Method for Trace Chloride in Liquid Aromatic Hydrocarbons
Description:
Significance and Use
4.1 Organic and inorganic chlorine compounds can have a deleterious effect on equipment and reactions in processes involving aromatic hydrocarbons.
4.2 Maximum chloride levels are often specified for process streams and for aromatic hydrocarbon products.
Scope
1.1 This test method covers the determination of total chloride (organic and inorganic) in liquid aromatic hydrocarbons and cyclohexane.
1.2 The test method is applicable to samples with chloride concentrations of 1 mg/kg to 25 mg/kg.
1.3 Bromides and iodides, if present, will be calculated as chlorides.
1.4 Materials, such as styrene, that are polymerized by sodium biphenyl reagent cannot be analyzed by this test method.
1.5 In determining the conformance of the test results using this method to applicable specifications, results shall be rounded off in accordance with the rounding-off method of Practice E29.
1.6 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
