    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) (M)5−y(HZO4)y(ZO4)3−y(X)1−y  (1) (M)5−y(HPO4)y(PO4)3−y(X)1−y  (2) (M)5−y+2n(HZO4)y(ZO4)3−y(X)1−y(SiO4)n  (3) (M)5−y+m(HZO4)y(ZO4)3−y(X)1−y(CO3)m  (4).

    Abstract: The catalytic oxidative dehydrogenation of at least one dehydrogenatable organic compound which has at least one ##STR1## grouping is carried out in the presence of a zinc titanate catalyst. The selectivity of the zinc titanate catalyst may be improved by a promoter at least one member of which is selected from the group consisting of chromium, antimony, bismuth, aluminum, phosphorus, indium, tin, lanthanum and cerium.
