What is the Disadvantage of ether as an extracting solvent?
Also, ether tends to form peroxides if left for a long period of time, which become explosive when concentrated (since these peroxides have a higher boiling point than that of ether). When removing your solvent after extraction, never evaporate ether to dryness. Always add some hexane near the end of the evaporation to co-evap any possible peroxides.
