After thermal equilibrium was established a recirculating stream of air was used to vaporize liquid [1] and to transport the vapor to the flask containing [2]. Five 10 mL aliquots were withdrawn into separatory funnels. The concentration of [1] in [2] was then determined by extraction into chloroform followed by UV-spectrophotometry. Standards for the spectrophotometry were prepared by weight from pure liquid solutes.", "reference": {"citation": "Sanemasa, I.; Araki, M.; Deguchi, T.; Nagai, H.; Chem.
