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.
一种经济优越的方法,用于制备没有添加溶剂的含有10到16个碳原子的环状碳醚物,其化学式为##STR1##其中R是一条直链或支链(C.sub.3 -C.sub.6)烷基或苄基,n为5-11个碳原子,该方法包括:(1)在惰性气氛下反应本质上由化学式为##STR2##其中n为5-11个碳原子的环状醇、约1.5-10摩尔当量的直链或支链(C.sub.3 -C.sub.6)烷基卤化物或苄基卤化物和金属氢化物的混合物。
