This operation is to be carried out in a well-ventilated area. Avoid open flame heating as much as possible. Be careful when choosing your still, the simultaneous increase in pressure and temperature could make the blend explosive.

Recovery of methanol can be obtained by the distillation of glycerol, by heating it at a temperature above 65% which is the boiling point of methanol. Methanol vapours then go through a condenser, are cooled down and collected in liquid form from the outlet.
