2-methoxyethyl-cyclododecenyl ether (I) is of interest as a precursor for the saturated ether, the fragrance 2-methoxyethyl-cyclododecyl ether (II), which is obtained by catalytic hydrogenation of (I) in high purity and with good fragrance quality.n n n To prepare 2-methoxyethyl-cyclododecenyl ether, 2-methoxyethanol and an orthoformate of the general formula (IV) in which R 1 denotes C 1 -C 4 -alkyl radicals, at temperatures from 50 to 250 ° C. in the presence of an acidic catalyst with cyclododecanone, optionally in the presence of a C 1 -C 4 -alkanol as solvent, and distills the low-boiling compounds formed in the process Connections. |
