Abstract: I n order to extract 1,2-dodecene oxide from its mixture with dodecene, the liquid-liquid equilibrium in the ternary system 1-dodecene—1,2-dodecene oxide—methanol was determined analytically at 0.5°C. It was found t h a t this mixture formed a system with one pair of partially miscible liquids. The values found experimentally were correlated by means of the Hand equation, the critical point was determined graphically, and the selectivity values of solvent were calculated. I t follows from the shape of ternary diagram as well as from the slope of conodes t h a t methanol is not a convenient extracting agent for the isolation of pure 1,2-dodecene oxide but it may be used for the separation of a part of pure 1-dodecene from its mixture with 1,2-dodecene oxide.
