Methanol → HCID 53826314, compound

Participants

Reaction Steps

340 g (1.67 M) of 2,5,9-trimethyl-cyclododeca-1,5,9-triene and 110 g of acidic diatomaceous earth in 5000 ml of methanol (containing less than 0.05% of water) were refluxed during 40 h. After cooling at room temperature and filtration, the mixture was concentrated at reduced pressure to yield, after a distillation, 366 g of a product having b.p. 79°-110°/0.01 Torr. After fractional distillation, 212 g of starting 2,5,9-trimethylcyclododeca-1,5,9-triene (b.p.43°-52°/0.1 Torr) and 140 g of the desired product, b.p. 78°-82°/0.01 Torr (yield 95% based on the converted starting material).
