1、Designation: D 1722 09Standard 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 last revision. A numb
2、er 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 Department of Defense.1. Scope*1.1 This test method covers the determination of the misci-bi
3、lity 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-immisciblecontaminants qualitatively; t
4、he 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, highmolecular weight
5、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 regarded asstandard.
6、No other units of measurement are included in thisstandard.1.5 For specific hazard information and guidance, consultthe suppliers Material Safety Data Sheet for materials listed inthis test method.1.6 This standard does not purport to address all of thesafety concerns, if any, associated with its us
7、e. 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.2. Referenced Documents2.1 ASTM Standards:2D 1193 Specification for Reagent Water3. Summary of Method3.1 The specimen
8、is diluted to 10 volumes with water andthe resulting mixture examined for cloudiness or turbidity.4. Significance 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 themi
9、scibility 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 specification. Prior to agreeing to this testmethod as the
10、 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 WaterReferences to water shall be understood to
11、mean reagent water conforming to Type IV or better ofSpecification D 1193.7. Procedure7.1 Transfer 25 mL of the sample to one of two clean250-mL graduated cylinders, dilute to the 250-mL mark withwater, and mix thoroughly. Allow any bubbles to rise to thesurface.7.2 Add 250 mL of water to the second
12、 cylinder and reserveas a blank.7.3 Compare the specimen solution with the water blank byviewing through the length of 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 und

Report8.1 If the specimen-water mixture is as free of cloudiness orturbidity as the blank, report the sample as “passes t
16、est.” If anycloudiness or turbidity is detected after 30 min, report as “failstest.”9. Precision and Bias9.1 No information is presented about either precision orbias of this test method for water miscibility of water-solublesolvents since the test result is nonquantitative and is reportedas pass or
