(Test Method)Standard Test Method for Determination of the Moisture Content of Sulfonated and Sulfated Oils by Distillation with Xylene
Standard Test Method for Determination of the Moisture Content of Sulfonated and Sulfated Oils by Distillation with Xylene
SIGNIFICANCE AND USE
This test method is intended to determine the moisture content of fats, oils, and fatliquors used in the softening and stuffing of leather. The moisture content is measured for the purpose of quality assurance.
SCOPE
1.1 This test method covers the determination of water existing in a sample of sulfonated or sulfated oil, or both, by distilling the sample with a volatile solvent. The test method is applicable only to sulfonated and sulfated oils that do not contain the following: mineral acids, free sulfonic acids, or free sulfuric acid esters; or alkali hydroxides, carbonates or acetates: or alcohol, glycerin, diethylene glycol, acetone, or other water-miscible volatile compounds. This test method was derived from Test Methods D500, Sections 4 through 9.
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are provided for information only.
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.
