ABSTRACT:
Disclosed is a method for producing an α,β-unsaturated ether efficiently and stably for a long time. In the method for producing an α,β-unsaturated ether, an acetal is thermally decomposed in the presence of a catalyst containing an apatite represented by any of the following formula (1)-(4)in-line-formulae description="In-line Formulae" end="lead"?(M)5−y(HZO4)y(ZO4)3−y(X)1−y  (1)in-line-formulae description="In-line Formulae" end="tail"?in-line-formulae description="In-line Formulae" end="lead"?(M)5−y(HPO4)y(PO4)3−y(X)1−y  (2)in-line-formulae description="In-line Formulae" end="tail"?in-line-formulae description="In-line Formulae" end="lead"?(M)5−y+2n(HZO4)y(ZO4)3−y(X)1−y(SiO4)n  (3)in-line-formulae description="In-line Formulae" end="tail"?in-line-formulae description="In-line Formulae" end="lead"?(M)5−y+m(HZO4)y(ZO4)3−y(X)1−y(CO3)m  (4).in-line-formulae description="In-line Formulae" end="tail"?
