Participants

Reaction Steps

550 g (2.7M) of 2,5,9-trimethyl-cyclododeca-1,5,9-triene and 380 g of acidic diatomaceous earth in 6250 ml of anhydrous ethanol were refluxed for 72 h to give, after the same treatment as that described in Example 1 above, 532 g of a product having b.p. 70°-110°/0.01 Torr. On fractional distillation, there were recovered 495 g of starting 2,5,9-trimethyl-cyclododeca-1,5,9-triene (b.p. 43°-52°/0.1 Torr) and 42.5 g of the desired product (b.p. 90°-105°/0.01 Torr); yield 63% based on the converted starting material.
