Physical properties of kerosene
Pure kerosene is a colorless, transparent liquid that is pale yellow when it contains impurities. Slightly smelly. The boiling range is 180-310 ° C (not absolute, it is often changed according to the specific conditions during production), and the freezing point is -47 ° C (-40 ° C for JET A). The average molecular weight is between 200 and 250. The density is 0.8 g/cm3. Melting point -40 ° C or more. The kinematic viscosity at 40 ° C is 1.0 to 2.0 mm 2 / s. Insoluble in water, soluble in alcohol and other organic solvents. volatile. combustible. After volatilization, it is mixed with air to form an explosive mixture. The explosion limit is 2-3%. Complete combustion, full brightness, stable flame, no black smoke, no knots, no obvious odor, less pollution to the environment.
