1、Designation: D1722 09 (Reapproved 2017)Standard Test Method forWater Miscibility of Water-Soluble Solvents1This standard is issued under the fixed designation D1722; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last

2、revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the U.S. Department of Defense.1. Scope1.1 This test method covers the determina

3、tion of the misci-bility of water-soluble solvents with water. While writtenspecifically for testing acetone, isopropyl alcohol(isopropanol), and methyl alcohol (methanol), the method issuitable for testing most water-soluble solvents.1.2 This test method serves to detect water-immisciblecontaminant

4、s qualitatively; the level of detection of theseimpurities varies widely with both the type of solvent and thetype of impurity.1.3 The level of detection of water-insoluble materialsdepends upon the solvent tested and the type of impurity orimpurities present, that is paraffin, olefin, aromatic, hig

5、hmolecular weight alcohol, or ketone, etc. There is, therefore, nospecific level of impurity detected by this procedure.NOTE 1This test method is normally performed at ambient, but othertemperatures may be used as specified by the consumer and supplier.1.4 The values stated in SI units are to be reg

6、arded asstandard. No other units of measurement are included in thisstandard.1.5 For specific hazard information and guidance, consultthe suppliers Safety Data Sheet for materials listed in this testmethod.1.6 This standard does not purport to address all of thesafety concerns, if any, associated wi

7、th its use. It is theresponsibility of the user of this standard to establish appro-priate safety, health, and environmental practices and deter-mine the applicability of regulatory limitations prior to use.1.7 This international standard was developed in accor-dance with internationally recognized

Significance and Use4.1 Water-insoluble materials present in a solvent expectedto be completely water miscible may interfere with many usesof the solven

10、t. This test method provides a measure of themiscibility of water-soluble solvents with a polar medium-water. It also provides a qualitative indication of the presenceor absence of water-immiscible contaminants.4.2 The results of this test method may be used in assessingcompliance with a specificati

Prior to agreeing to this testmethod as the basis of a specification requirement, it may bedesirable that the interpretation of what constitutes cloudinessor turbidity be agreed upon between the supplier and thepurchaser.5. Apparatus5.1 Cylinder, graduated, glass-stoppered, 250-mL.6. Reagent6.1
