【国外标准】 Standard Test Methods for Chemical Analysis of Alpha Olefin Sulfonates

33.1 This method is suitable as a quality control test for the measurement of color in alpha olefin sulfonates.1.1 These test methods cover the chemical analysis of alpha olefin sulfonates. The analytical procedures appear in the following order:  Sections Moisture by the Distillation Method 4 – 8 Sodium Sulfate  9 – 14 Neutral Oil 15 – 19 Chlorides Calculated as Sodium Chloride (NaCl) 20 – 24 Alkalinity 25 – 29 pH 30 and 31 Determination of Color 32 – 37 Determination of Active Content by Methylene Blue Titration 38 – 471.2 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. For specific precaution statement see 36.1. Material safety data sheets are available for reagents and materials. Review them for hazards prior to usage.
