Abstract

A production process for cyclic ether, which comprises undergoing dehydration ring-formation reaction of alkanediol containing more than 3 carbons and 2 hydroxyl group per molecule at 70~250 deg.C and the presence of alkanesulfonic acid catalyst to obtain cyclic ether in which the alkanesulfonic acid is linear or branchedalkanesulfonic acid with 1~4 carbons in its alkyl group.
