What is the Difference Between Xylene and Acetone?
The key difference between xylene and acetone is that xylene is a cheap and less toxic solvent, whereas acetone is an expensive and more toxic solvent. Moreover, xylene is nonpolar, and acetone is less polar; therefore, xylene can dissolve lipophilic substances, but acetone can dissolve both lipophilic and hydrophilic substances.
