Determination Method for Kinematic Viscosity of Diesel Oil No. 0
Diesel Oil No. 0 belongs to the light diesel oil category, which is a mixture of complex hydrocarbons (with approximately 10 to 22 carbon atoms). Under normal conditions, it is a clear and transparent liquid, appearing light yellow, yellow, or water-white, with a greasy or pungent odor. At 20°C, its density ranges from approximately 0.8400 to 0.8600 g/cm³, and its boiling point ranges from about 180°C to 370°C. It features low energy consumption and low pollution, and is widely used in vehicles, ships, and construction machinery.
Purpose of the Experiment：
In the fields of chemistry and scientific research, by determining the kinematic viscosity of Diesel Oil No. 0, the combustion performance of the diesel oil can be evaluated, the introduction of impurities in the product during the production process can be monitored, and product quality can be ensured.
Experimental Instruments & Samples：
Experimental Samples：Diesel Oil No. 0
Experimental Instrument：
①SH112G Automatic Ubbelohde kinematic viscometer
②Optional accessories such as solvent oil, petroleum ether, sample injection tubes, and capillary viscometers that comply with GB/T 265 and ASTM D445.
Testing method：
①Start the instrument and set the constant temperature bath temperature and other parameters according to the experimental requirements.
②Prepare the Ubbelohde viscometer and the sample to be tested, ensuring the Ubbelohde viscometer is clean, dry, and accurately calibrated.
③Inject the sample to be tested into the measuring tube.
④Place the viscometer vertically in the constant temperature water bath; the instrument will automatically time, calculate the results, and print them.
⑤Repeat the measurement 3 times or more to ensure the accuracy and reliability of the results.
Experimental Results
Through testing and analysis, the kinematic viscosity of Diesel Oil No. 0 in this batch ranges from 3.0 to 8.0 mm²/s, which meets the standards.
