摘要：
PROBLEM TO BE SOLVED: To provide a method for efficiently producing an α,β-unsaturated ether stably over a long period of time through reactivating a catalyst to have a longer service life.
SOLUTION: The method for producing the α,β-unsaturated ether of general formula (3): R
1 R
2 C=C-R
3 (OR
4 ) comprises thermally decomposing the corresponding acetal of general formula (2): R
1 R
2 CH-CR
3 (OR
4 )
2 in a vapor phase in the presence of a catalyst and a compound having in the molecule at least one hydrogen atom formable of a hydrogen bond. In the general formulas (2) and (3), R
1 , R
2 and R
3 are each independently H, an alkyl, alkenyl or aryl; R
4 is an alkyl, alkenyl or aryl, wherein, a plurality of the groups R
4 in the formula (2) may be the same as or different from each other.
