Procedure
20 Parts of 1,1-di-(3-methyl-2-butenyloxy)-3-methyl-2-butene which was synthesized in Example 1, 43 parts of xylene, and 0.1 part of ammonium nitrate were charged in a flask, and the xylene was distilled off under reduced pressure (20 mmHg). Thereafter the bath temperature was maintained at not higher than 100°C., and the distillate was collected until the reaction was completed. Re-distilling the so obtained distillate, 5.15 parts of a fraction of a distillate boiling at 46.5°C./0.1 mmHg was obtained, which was confirmed to be 1-(3-methyl-2-butenyloxy)-3-methyl-1,3-butadiene from the results of IR, NMR, and high resolving power mass spectrum analyses. The analyses data are shown in Table 9.
