【国外标准】 Standard Test Methods of Chemical Analysis of Sulfonated and Sulfated Oils

AbstractThese test methods cover the chemical analysis of sulfonated and sulfated oils. Water by distillation with volatile solvent and moisture and volatile matter by hot-plate shall be tested to meet the requirements prescribed. Titration test, extraction-titration test, and ash-gravimetric test shall be performed to meet the requirements specified. Total desulfated fatty matter, total active ingredients, unsaponifiable non-volatile matter, inorganic salts, total alkalinity, and total ammonia shall be tested to meet the requirements prescribed. In the absence of ammonium or triethanolamine soaps test method, brine test method, and in the presence of ammonium or triethanolamine soaps test method shall be performed to meet the requirements prescribed. Water-immiscible organic solvents volatile with steam shall be tested to meet the requirements prescribed.1.1 These test methods cover the chemical analysis of sulfonated and sulfated oils. The analytical procedures appear in the following order:  Section   Moisture:   Test Method A. Water by Distillation with Volatile Solvent 4 – 9 Test Method B. Moisture and Volatile Matter by Hot-Plate Method 10 – 14Organically Combined Sulfuric Anhydride:   Test Method A. Titration Test 15 – 19 Test Method B. Extraction-Titration Test 20 – 24 Test Method C. Ash-Gravimetric Test (in the Presence of TrueSulfonates) 25 – 28Total Desulfated Fatty Matter 29 – 32Total Active Ingredients 33 – 36Unsaponifiable Nonvolatile Matter 37 – 41Inorganic Salts 42 – 46Total Alkalinity 47 – 49Total Ammonia 50 – 52Acidity as Free Fatty Acids or Acid Number:   Test Method A. In the Absence of Ammonium or Triethanolamine Soaps 53 – 56 Test Method B. In the Presence of Dark Colored Oils but in theAbsence of Ammonium or Triethanolamine Soaps (Brine Test) 57 – 60 Test Method C. In the Presence of Ammonium or Triethanolamine Soaps 61 – 63Water-Immiscible Organic Solvents Volatile with Steam 64 – 701.2 The values stated in inch-pound units are to be regarded as the standard. The metric equivalents of inch-pound units may be approximate.1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use.
