Description

Pos t Labr epor t1 Beshoy Samwel TA:Kyle Pedretty, Simple and Fractional Distillation of a binary mixture. Introduction The Aim of this experiment was to perform a simple and fractional distillation order to separate a mixture of two liquid. The boiling point of the liquid is the temperature where the liquid in a certain degree which its vapor pressure is equal to the pressure of the gas above it. Raoul’s law is chemical law that the vapor pressure solution will be dependent on the fraction of the solute. Daltons ‘law is a partial pressure of a individual component gasses states that the total pressure in system. Di scussazeot r opesbygi vi ngexampl es.

Percent recovery of cyclohexane=100*(3.5/3.5)=100% Perecnt of recovery of toluene= 100*(2.5/3.5)71% Discussion’ Temperature decreases toward the top allowing the compound to condense and drip back down the column. After collecting 3.5 ml of cyclohexane in one receiver and 3.5 ml of toluene in another receiver, the distillation is now over, stop the distillation and allow the apparatus to cool. When heating starts, monitor the temperature at constant rate to allow good separation of the solvents ,`...
