1、Designation: D 1722 98 (Reapproved 2004)Standard Test Method forWater Miscibility of Water-Soluble Solvents1This standard is issued under the fixed designation D 1722; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of las

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

3、on of the misci-bility of water-soluble solvents with water. While writtenspecifically for testing acetone, isopropyl alcohol (isopro-panol), and methyl alcohol (methanol), the method is suitablefor 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 This standard does not purport to address a

6、ll of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.1.5 For specific hazard information and guidance, consultthe s

Summary of Method3.1 The specimen is diluted to 10 volumes with water andthe resulting mixture examined for cloudiness or turbidity.4. Signi

8、ficance and Use4.1 Water-insoluble materials present in a solvent expectedto be completely water miscible may interfere with many usesof the solvent. This test method provides a measure of themiscibility of water-soluble solvents with a polar medium-water. It also provides a qualitative indication o

9、f the presenceor absence of water-immiscible contaminants.4.2 The results of this test method may be used in assessingcompliance with a specification. Prior to agreeing to this testmethod as the basis of a specification requirement, it may bedesirable that the interpretation of what constitutes clou

10、dinessor turbidity be agreed upon between the supplier and thepurchaser.5. Apparatus5.1 Cylinder, graduated, glass-stoppered, 250-mL.6. Reagent6.1 WaterReferences to water shall be understood tomean reagent water conforming to Type IV of SpecificationD 1193.7. Procedure7.1 Transfer 25 mL of the samp

11、le to one of two clean250-mL graduated cylinders, dilute to the 250mL mark withwater, and mix thoroughly. Allow any bubbles to rise to thesurface.7.2 Add 250 mL of water to the second cylinder and reserveas a blank.7.3 Compare the specimen solution with the water blank byviewing through the length o

12、f the column of liquid toward adark background. When an artificial light source is used,position the light so that it passes transversely through thecylinders.1This test method is under the jurisdiction of ASTM Committee D01 on Paintand Related Coatings, Materials, and Applications and is the direct
