Abstract

A convenient and inexpensive method for insulating fractional distillation columns in undergraduate laboratories with pre-slit, tubular pipe insulation that is widely available in hardware stores is described. This insulation can be quickly employed, can provide uniform insulation, and can be reused, which reduces the amount of trash generated from commonly used insulation.

[5]  Distillations were performed in an open fume hood with 25 mL of a 50% (v/v) methanol and 1-propanol mixture contained in a 100 mL round bottom flask and heated with a Powermite-controlled 100 mL Thermowell heating mantle as part of the distillation apparatus as referenced in Figure 1– except for the incorporation of a Vigreux column that was either left uncovered, insulated with tubular polyethylene foam, or insulated with a layer paper towels and aluminum foil, respectively. Each of these experiments employed similar Powermite control settings throughout the duration of the distillations to facilitate a slow rise of the condensate through the fractionating column and the collection of distillate at similar a pace during similar points of each separation (i.e. 3-5 sec per drop for the collection of methanol and 1.5-3 sec per drop for the collection of 1-propanol).
