Organic and inorganic chlorine compounds can have a deleterious effect on equipment and reactions in processes involving aromatic hydrocarbons. Maximum chloride levels are often specified for process streams and for aromatic hydrocarbon products.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 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. 1.7 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 and health practices and determine the applicability of regulatory limitations prior to use. For a specific hazard statement, see Section 7.

This test method is suitable for determining the quantity of aldehydes, both for quality control and quality assurance of the product.1.1 This test method covers the wet chemical determination of aldehydes in styrene monomer. Aldehydes are calculated and reported as benzaldehyde. The range of concentration for this test method is 0.001 mass % to 0.030 mass %. 1.2 In determining 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. 1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this 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 and health practices and determine the applicability of regulatory limitations prior to use.

This test method is useful for determining organic as well as inorganic chloride compounds that can prove harmful to equipment and reactions in processes involving hydrocarbons. The combination of both the organic and inorganic chloride is commonly termed “total chloride” and since the inorganic chlorides are partially recovered, the result for total chloride will be biased low. Maximum chloride levels are often specified for process streams and for hydrocarbon products. Organic chloride species are potentially damaging to refinery processes. Hydrochloric acid can be produced in hydro treating or reforming reactors and this acid accumulates in condensing regions of the refinery.1.1 This test method covers the measurement of chloride in aromatic hydrocarbons, their derivatives, and related chemicals as defined by the method. Aromatics typically do not have any source of chlorides other than organic. The presence of metallic or inorganic chlorides is theoretically possible but not likely and this method does not purport to address recovery of those compounds. 1.2 This test method is applicable to samples with chloride concentrations from 0.24 to 5.0 mg/kg. The test method limit of detection (LOD) is 0.07 mg/kg. 1.3 This test method is preferred over Test Method D5194 for products, such as styrene, that are polymerized by the sodium biphenyl reagent. 1.4 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. 1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.6 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 and health practices and determine the applicability of regulatory limitations prior to use.

This practice is issued to provide information useful in establishing sampling and handling procedures. It is expected that this information will only be utilized in conjunction with an existing health and safety program and consultation with an appropriate MSDS. The information provided herein cannot be used as a substitute for expert safety and medical advice as provided in appropriate MSDS, but rather as a supplement to such advice.1.1 This practice covers procedures for sampling and handling several liquid cyclic products. These specifically cover liquids at ambient temperature and include benzene, toluene, xylenes, cyclohexane, styrene, pyridine, ethylbenzene, isopropylbenzene, and alpha-methylstyrene. 1.2 Any person sampling and handling these products should have specific first aid instructions and equipment available for use in the event of personal contact or exposure. 1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that 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 and health practices and determine the applicability of regulatory limitations prior to use. For specific hazard statements, see Sections 5, 6 and 7.

1.1 This test method covers determination of nonylphenol (NP), nonylphenol ethoxylate (NP1EO), nonylphenol diethoxylate (NP2EO), octylphenol (OP), and bisphenol A (BPA) that are partitioned into organic solvent, separated using gas chromatography and detected with mass selective detection. These compounds or isomer mixtures are qualitatively and quantitatively determined by this method. This method adheres to selected ion monitoring mass spectrometry but full scan mass spectrometry has also been shown to work well under these conditions. Either analysis may be used. 1.2 The method detection limit (MDL) and reporting limit (RL) for NP, NP1EO, NP2EO, OP, and BPA are listed in Table 1.TABLE 1 MDL and Reporting Limits Analyte
