Abstract
2-Methoxyethyl cyclododec-1-enyl ether is of interest as a precursor for the saturated ether, 2-methoxyethyl cyclododecyl ether, which can be obtained therefrom by catalytic hydrogenation, in a high purity and with a good fragrance quality. The saturated ether is a valuable fragrance component having a woody note. A process for producing 2-methylethyl cyclododec-1-enyl ether comprises the step of reacting cyclododecanone, 2-methoxyethanol and a tri(lower alkyl) orthoformate, at a temperature of 50.degree.-250.degree. C., in the presence of an acid catalyst, removing resultant low-boiling compounds by distillation, and recovering resultant 2-methoxyethyl cyclododec-1-enyl ether.
