3 Test Method

3.1 General provisions Tests Unless otherwise specified, the reagents used were of analytical grade. Water as carbon dioxide-free distilled water (according to GB/T 603 specified party Preparation) or equivalent purity water. 3.2 densitometry 3.2.1 pycnometer method At 20 ℃ constant temperature, the volume of pycnometer Calibration with distilled water, and then determine the mass of the same volume of the sample, find its density, results ρ20 (g/mL) indicates. 3.2.1.1 Instruments a) pycnometer. The proportion 25mL bottle attached thermometer GB/T 4472 regulations. b) constant temperature water bath. temperature controlled at (20 ± 0.1) ℃. 3.2.1.2 Test procedure Cooled to about 15 ℃ distilled water filled pycnometer was washed, insert the thermometer, no bubbles remain flask, placed in a water bath, After 30min, with filter paper to absorb the overflow capillary water and stamped, remove the pycnometer wipe, weighed (accurate to 0.0002g). The specific gravity bottle of water poured out, first with ethanol, washed several times with ether, dry and weighed. Water is the difference between the two weights at 20 ℃ quality. With alcohol instead of water, supra operation, that was the quality of alcohol at 20 ℃. ......
