Since many synthesis procedures utilize high purity ethanol, methanol, etc... as the solvent in synthesis procedures such as the Stober process, I assume there should be a couple of recovery methods for the alcohol. What kind of different methods are out there? I'm looking for both lab scale and commercial scale methods. Thanks!
After Completion of reaction we can recover alcohol by fractional distillation method.
Hi,
After the reaction is complete, normally every chemist performs vacuum evaporation to remove solvent. This is the step where you can recover your solvent in pure form. Before subjecting your mixture to rotary evaporator, clean the condenser and collecting flask properly. Thereafter, if your reaction mixture contains only one solvent i.e. Ethanol, then you would get pure ethanol in collecting flask. It can be reused. But if your reaction mixture is having mixture of solvents then the collecting flask would have different solvents. So, in this case you need to perform fractional distillation.
Thanks
