distillation

distillation

the process of vaporizing a liquid mixture in one vessel condensing the vapors into another vessel

distillation is the separation of compounds of a. mixture based on

boiling point

where does the water come in through

the bottom

where does the water come out from

at the top

boiling point

temperature where vapor pressure equals atmospheric pressure

vapor pressure

pressure exerted by liquid and solids due to evaporation

principle of distillation - a mixture of two (or more) liquids with different vapor pressures will boil when

the total vapor pressure over the mixture equals the external pressure, but the composition of the vapor will be different from that of the liquid itself

distillation - it contains more of the

lower boiling component than does th liquid mixture itself

distillation purifies organic compounds

by exploiting differences in their boiling points, separating liquids through repeated cycles of vaporization and condensation, with more volatile (lower boiling point) components vaporizing first, then being collected as pure distillate, leaving impurities behind
