The method according to the invention includes contacting a glycol with a monohydric alcohol in the presence of a polyperfluorosulfonic acid resin catalyst under conditions effective to produce the glyme. The method of the invention can be used to produce, for example, monoglyme, ethyl glyme, diglyme, ethyl diglyme, triglyme, butyl diglyme, tetraglyme, and their respective corresponding monoalkyl ethers. The present invention also provides a method of producing 1,4-dioxane from mono- or diethylene glycol and tetrahydrofuran from 1,4-butanediol.
