WebDissolve Oils into an Organic Solvent (Extraction from Aqueous Layer) Place the distillate in a separatory funnel and extract with three portions (-15 mL each) of dichloromethane (methylene chloride, CH2Cl2). Remember, the bottom layer is the more dense liquid - the organic layer in this case! Shake gently at first since dichloromethane can ... Webimmiscible with water and has a higher density then water. Therefore, dichloromethane will always be the bottom layer of the two liquid layers formed when water is added to it. IMPORTANT SAFETY CAUTIONS: 1. Aqueous HCl and NaOH (6M and 3M) are strongly acidic and basic reagents respectively.
