Testing method
A.1 General Provisions
Unless otherwise indicated in the analysis using only recognized as analytical reagents and GB/T 6682 stipulated three water.
The test method used in the standard titration solution, impurities measured by standard solution, preparations and products, not specified in other requirements, according
GB/T 601, the provisions of the preparation of GB/T 602 and GB/T 603's. The solution in a solvent which does not indicate by when formulated, refers to an aqueous solution.
A.2 Identification Test
A.2.1 Determination of Infrared Spectra
By infrared absorption spectrophotometry, the sample spectrum and the control spectrum (see Appendix B) Comparison of the two should be basically the same.
A.2.2 Determination of vapor pressure
According to GB/T 22026-2008 Determination of the method in 4.6. 21 ℃ sample vapor pressure (absolute pressure) should
Is 820kPa ~ 875kPa.
A.3 Determination of sulfide
The sample cylinder valve is opened, the formation of air appropriate to adjust the flow, do not direct the airflow to the face, the reflective part of the airflow toward the nose, sniffing
Its taste. No specific sample sulfide odor is by testing.
A.4 Determination of residue acidity
Take the high-boiling residue sample after measurement, add water to dissolve 10mL, add 2 drops to 3 drops of methyl orange indicator solution (1g/L), no pink or red
Color is produced by the test.
