What is the disadvantage of using a distillation flask whose capacity is four or five times (or more) the volume of the liquid being distilled?
Homework Answers
Two things should be remembered ehil Doing distillation
- UNPIRIFIED LIQUID SHOULD NOT LESS THAN HALF -FILLED-FILLED
Because there may be the chance of bumping the liquid and unpurified liquid would contaminate the Condenser As well as Undistilled liquid.
2. ) DISTILLATION FLASK SHOULD NOT BE OF 4 TO 5 TIMES CAPACITY .
Because this will Lower the yield of Distillation i,e ( purified liquid will be much lower in yield as expected ) because Considerable Heat Loss occurs from such big volume of flask which directly effect Rate of Distillation as well as yield.
Rate of Distillation would also be Reduced and will be more time consuming.

Five hundred kmol/h of liquid alcohols containing, by moles, 40% methanol (M), 35% ethanol (E), l 5% isopropanol (IP), and 10% normal propanol (NP) are distilled in two distillation columns. The distillate from the first column is 98% pure M with a 96% recovery of M. The distillate from the second is 92% pure E with a 95% recovery of E fromn the process feed. Assume no propanols in the distillate from Column...
