What is Difference between volatility and evaporation?

Evaporate is a phase change from liquid to gas without changing the molecule itself (or the atoms is the liquid is atomic). Volatility is essentially the tendency of a liquid to evaporate. So a highly volatile liquid would show a great tendency to evaporate. A measure of volatility is the vapor pressure. read more

In either case the process exploits differences in the volatility of mixture's components. In industrial chemistry, distillation is a unit operation of practically universal importance, but it is a physical separation process and not a chemical reaction. read more
