Question

In a fractional distillation experiment it is important to wrap insulting tape and Al foil around the length of the fractionating column. Why do you think this is necessary?

Expert Solution

Step 1

Wrap the distillation column with an insulated like Aluminium foil insulation bill aloud the vapour to travel all the way to the top of the column and out the condenser. the increase in efficiency results from the repeated interaction with the column packing.

Paked columns are used for distillation gas absorption and liquid liquid extraction the gas liquid contact in a packed column is continuous not stagewise as in a plate column. the liquid flows down in the column over a writing surface and the vapour moves counter currently up the column
