An economically advantageous method is disclosed for the preparation without added solvent of a carbocyclic ether having from 10 to 16 carbon atoms in the ring of the formula ##STR1## wherein R is a straight or branched (C.sub.3 -C.sub.6) chain alkyl group or a benzyl group and n is from 5-11 carbon atoms, which method comprises: (1) reacting under an inert atmosphere a mixture consisting essentially of a carbocyclic alcohol of the formula ##STR2## wherein n is from 5-11 carbon atoms, about 1.5-10 molar equivalents of a straight or branch (C.sub.3 -C.sub.6) chain alkyl halide or benzyl halide and a metal hydride.
