Chloroform Or Ethyl Acetate Rotary Evaporator

Chloroform Or Ethyl Acetate Rotary Evaporator

A rotary evaporator is a device used in chemical laboratories for the efficient and gentle removal of solvents from samples by evaporation. Rotary evaporation is most often and conveniently applied to separate “low boiling” solvents such as n-hexane or ethyl acetate from compounds that are solid at room temperature and pressure.

on the rotary evaporator, ethyl acetate also works well but is harder to remove, dichloromethane is a poor choice and should be avoided, if possible, since it often forms nasty emulsions and complicates matters because it is heavier than water. 2) Pick the size of your separatory (sep.) funnel - usually 125 or 250-mL, large scale.
