To provide a process for producing an acetal group-free ether compound having excellent water resistance and stability by adding an active hydrogen-containing compound to the position-2 carbon in a propenyl ether group with a high selectivity in the reaction of adding the active hydrogen-containing compound to a propenyl ether group-containing compound.

The process for producing the ether compound (D1) represented by formula (4) comprises reacting an active hydrogen-containing compound (A1) represented by formula (1) with a propenyl ether group-containing compound (B1) represented by formula (2) in the presence of an acid catalyst (C) and the process for producing the ether compound (D2) represented by formula (8) (not shown) comprises reacting an active hydrogen-containing compound (A2) represented by formula (5) (not shown) with a propenyl ether group-containing compound (B2) represented by formula (7) (not shown) in the presence of the acid catalyst (C).
