The process involves employing a volatile solvent to purify a substance. It aims to remove impurities and unwanted byproducts from a compound, resulting in a higher concentration of the desired material. For instance, if a particular crystalline substance contains contaminants that affect its purity or appearance, this technique might be used to isolate the target compound.
The perceived advantage lies in obtaining a purer form of the substance, potentially increasing its potency or improving its appearance. Historically, such methods have been employed in clandestine settings to refine illicitly produced substances. However, the application of these techniques carries significant risks, including fire hazards due to the flammability of the solvent, potential explosions, and exposure to harmful chemicals. It is important to acknowledge that attempting to purify illegal substances does not make its use or distribution legal.
