Can you substitute diethyl ether for DCM, as an extraction solvent?
Accepted Answer
Diethyl ether and DCM (dichloromethane) are both common organic solvents used in extractions. However, they have different properties that make them suitable for different situations.
Diethyl ether is a more volatile and less dense solvent than DCM. It is often used to extract organic compounds from aqueous solutions, as it is immiscible with water and has a lower boiling point, making it easier to remove by evaporation. However, diethyl ether is highly flammable and can form explosive peroxides upon prolonged exposure to air.
DCM is a denser and less volatile solvent than diethyl ether. It is often used to extract organic compounds from aqueous solutions, as it is also immiscible with water. DCM is less flammable than diethyl ether and does not form explosive peroxides.
Therefore, whether you can substitute diethyl ether for DCM depends on the specific extraction you are performing. Consider factors like the solubility of the compound you are extracting, the boiling points of the solvents, and safety considerations.
