ASTM D5562-95(2006) 存在铵或三乙醇胺皂时酸度作为游离脂肪酸值测定的标准试验方法

This test method is intended for use in the determination of the acid number of sulfonated and sulfated oils for the purpose of quality assurance.1.1 This test method covers determination of the acidity as free fatty acids in the presence of ammonium or triethanolamine soaps, or both, existing in a sample of sulfonated or sulfated oil, or both, by calculation from the total alkalinity and free-and-alkali combined fatty acids. 1.2 The values in SI units are to be regarded as the standard. 1.3 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.

Standard Test Method for Determination of the Acidity as Free Fatty Acids/Acid Number in the Presence of Ammonium or Triethanolamine Soaps

ASTM E1616-94(2002)e1 用气相色谱法分析乙酸酐的标准试验方法

This test method provides for the determination of assay and impurities in acetic anhydride. Acetic anhydride is used as an intermediate in many chemical processes. Its relative concentration affects the efficiency of these processes. This test method provides a test procedure for assay and impurity specification acceptance as well as manufacturing control.1.1 This test method describes the determination of assay and impurities in acetic anhydride by gas chromatography. The acetic anhydride should be at least 95 % pure. 1.2 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 hazards statements see Section 9.

Standard Specification for Acrylic Acid

ASTM D4711-89(2009) 烷基苯磺酸中磺酸与硫酸的标准试验方法

Alkylbenzene sulfonic acids are important intermediates in the synthetic detergent industry and are defined under “alkyl benzene sulfonate” in Terminology D459. This test method is suitable for the rapid monitoring of the sulfonic and sulfuric acid levels, both of which have a vital bearing on final product performance and appearance.1.1 This test method is applicable to the determination of sulfonic and sulfuric acids in branched and linear alkylbenzene sulfonic acids used as intermediates in synthetic detergents. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.3 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. Material Safety Data Sheets are available for reagents and materials. Review them for hazards prior to usage.
