    Abstract: PROBLEM TO BE SOLVED: To simply produce an ether compound useful as a solvent, etc., from a carbonyl compound in a hydrogen atmosphere in one stage at a low cost by utilizing the availability of a symmetric type ether compound in high yield by using a catalyst. SOLUTION: Aliphatic aldehydes or ketones of formula I (R1 and R2 are each independently a 1-20C alkyl, etc.) are reacted by using a catalyst such as a palladium catalyst supported on carbon, etc., in a hydrogen atmosphere and the reaction is made to proceed while removing water formed as a by- product to the outside of the system and returning the unreacted raw materials discharged together with the water to the outside of the system thereinto to thereby afford the objective ether compound of formula II.
