On the relationship between boiling point and relative volatility
Thread Content
Is it true that components with low boiling points are volatile, while those with high boiling points are non-volatile?
Not necessarily; some substances have a high boiling point but are highly volatile, such as ethanol
Relative volatility certainly refers to two or more components. This is related to the activity coefficient. I came across a question that none of the CEOs of companies specializing in distillation were able to answer: If water contains 0.001 mole fractions of methanol, ethanol, isopropanol, n-propanol, and n-butanol, and air is used for countercurrent contact desorption, which alcohol is easiest to remove?
