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。
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。
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 experimental results showed that DMF with salt had higher relative volatility of C4 and was better than DMF for separating C4.
