The present invention relates to a novel thermo-isomerization method for rapidly and simply producing macrocyclic ketones of the formula Ia or Ib.
1
The macrocyclic ketones are prepared in the gas phase at temperatures above 500° C. rapidly and in a simple manner from alcohols of the formula IIa and IIb directly with a high yield.
2
In the formulae Ia, Ib, IIa and IIb, R
1
-R
5,
and n have the meanings given in the description.
