Dialkyl ethers and alkyl fluoroalkyl ethers are obtained in excellent yields by the reaction of alcohols and carbonyl compounds in the presence of Pd/C under the atmospheric pressure of hydrogen, when water produced by the reaction is continuously removed by bubbling hydrogen through the reaction mixture.

Unsymmetrical ethers are obtained in excellent yields by the catalytic etherification of alcohols with ketones or aldehydes in the presence of Pd/C under an atmospheric pressure of hydrogen when water produced by the reaction is continuously removed by bubbling hydrogen through the reaction mixture.
