Rotary Evaporator Of Ethanol

Rotary Evaporator Of Ethanol

Apr 18, 2020 Ethanol content of the produced samples were then measured after 90 or 120 min of rotary evaporation. Ethanol percentage in all samples were reduced to less than 10% after 90 min of rotary evaporation, whereas a further reduction to almost 0% for ethanol was found following an additional 30 min of evaporation process (Fig. 2).

Rotary Evaporator Of Ethanol

Mar 05, 2020 To separate the two, use a rotary evaporator. When connected to a vacuum pump, the rotary evaporator uses the vacuum to lower the boiling point of ethanol, resulting in a quicker evaporation. The resulting extract or oil will be completely free of ethanol. This process also allows ethanol to be recovered for additional extractions.
