Method/Apparatus/Procedure:
   The synthetic method was used. Miscibility was determined in a glass-stoppered tube of 4 mm inside diameter. Equal volumes (0.1 mL) of (1) and (2) were measured into the tube which was then strapped to a thermometer, warmed to 5 or 10 °C above the solubility temperature, mixed well by shaking, and then allowed to cool slowly, still shaking, in a bath of white oil (above 30 °C) or water (below 30 °C).

Source and Purity of Materials:
   (1) Not specified.
   (2) 2-pentene synthesized in the Research Lab of Organic Chemistry Massachusetts Institute of Technology; some alkenes (*) were obtained from Dr. H. E. Buc, Standard Oil Development Co.; the others were the purest commercial samples available from BDH.
