    Abstract: The invention relates to a method of producing an ethylenically unsaturated carboxylic acid or ester, preferably an α, β ethylenically unsaturated carboxylic acid or ester. The method includes contacting formaldehyde or a suitable source thereof with a carboxylic acid or ester in the presence of a catalyst and optionally in the presence of an alcohol. The catalyst comprises a nitrided metal oxide having at least two types of metal cations, M1 and M2, wherein M1 is selected from the metals of group 2, 3, 4, 13 (called also IIIA) or 14 (called also IVA) of the periodic table and M2 is selected from the metals of groups 5 or 15 (called also VA) of the periodic table. The invention extends to a catalyst system.

    Abstract translation: 本发明涉及一种制备烯属不饱和羧酸或酯,优选α,β-烯属不饱和羧酸或酯的方法。 该方法包括在催化剂存在下和任选在醇存在下使甲醛或其合适的来源与羧酸或酯接触。 催化剂包括具有至少两种金属阳离子M1和M2的氮化金属氧化物,其中M1选自第2,3,4,13族(也称为IIIA)或14(也称为IVA)的金属, 周期表和M2选自元素周期表第5或15族(也称为VA)的金属。 本发明延伸到催化剂体系。
