Abstract: Improved methods for making ethers. In particular, an alkoxide can be more effectively converted into an ether by reaction with a hydrocarbyl halide in the presence of a substantial excess of a hygroscopic base such as NaOH. When present in such an unconventional excess, the base serves multiple functions. As a consequence, the alkoxide is extensively converted to the desired ether rapidly at excellent yields. The reaction environment also aids later product isolation. The use of the NaOH rather than Na metal allows the ether product to be separated from water soluble impurities such as salt products, left over base, left over hydrocarbyl halide, formates, etc. by liquid-liquid extraction among aqueous and organic phases.
