Efficiency of conventional separation, namely azeotropic distillation or extractive distillation, was relatively low due to very close relative volatility of benzene and cyclohexane.
由于苯和环己烷的相对挥发度非常接近,利用传统分离方法(如萃取精馏或共沸精馏)分离苯-环己烷混合物的分离效率较低。
The experimental results showed that DMF with salt had higher relative volatility of C4 and was better than DMF for separating C4.
实验结果表明,加盐DMF分离能力强于溶剂DMF,C4在同温同压下的相对挥发度比DMF中的大。
The results showed that addition of appropriate extracting solvent could increase the relative volatility of active amyl alcohol and decrease the number of theoretical plates.
结果表明,加入合适的萃取剂可有效地提高旋光性戊醇对异戊醇的相对挥发度,减少分离所需的理论板数。
Because of its low relative volatility with other components in system and its heat sensitivity, the separation difficulties and energy consumption are increased.
因其与其它组分间的相对挥发度很小,且本身又是热敏性物料,故分离难度大,能耗高。
Physical properties refer to viscosity, density, surface tension, diffusion coefficient, relative volatility and so on.
物系性质主要指粘度、密度、表面张力、扩散系数及相对挥发度等。
