摘要

以中低温煤焦油为原料,经实沸点蒸馏切割成17个窄馏分,对每个馏分测定其在不同温度下的密度,得出密度随温度的升高而变小,具有很好的线性关系,经过理论计算和推导,得出体胀系数E和线性系数也呈线性关系。依据每个馏分段在不同温度下的运动黏度,通过计算得出动力黏度,发现动力黏度随着温度的升高而降低,而且符合Vogel关系式。
        The mid-low temperature coal tar as sample oil, and 17 close cut fractions were gained by the true boiling point distillation. The specific density and dynamic viscosity were determined at different temperatures, and the relationships between properties and the average boiling points were correlated.The specific density decreases with temperature rising according to a linear relation, and volume expansion coefficients are deduced from the linear coefficients. The kinetic viscosity decreases with temperature rising according to Vogel equation.
