After concentrated sulfuric acid was mixed into the whale blubber fluids (producing a black, viscous mixture), Teuten added hexane to help separate the needed halogenated compounds from the mix of fat and acid. In the photo, the golden liquid in the top flask is the hexane-halogen mixture, while the blackened mix of lipids and acid filter through a seperatory funnel (middle) into a beaker on the bottom.
