Abstract

PURPOSE:To sustain catalytic activity for a long period and obtain (meth)acrylic acids, by containing a specific amount of molecular O2 in a raw material gas containing saturated monocarboxylic acids and formaldehydes and bringing the resultant raw material gas into contact with a catalyst containing a P-V-Ti- O based component. CONSTITUTION:Molecular oxygen in an amount of 0.1-10vol.% based on a raw material gas containing saturated monocarboxylic acids and/or esters thereof, such as acetic acid and/or an ester thereof or propionic acid and/or an ester thereof, and formaldehyde and/or a derivative thereof is contained therein and then methanol or water or both are contained. The resultant raw material gas is subsequently brought into contact with a catalyst containing a component expressed by the formula (P, V, Ti and O are respectively phosphorus, vanadium, titanium and oxygen; a-d are the numbers of P, V, Ti and O atoms; b is 2-20mol.%; c is 10-50mol.%; d is the number of atoms required to satisfy the valences of the components except O when a+b+c is 100mol.%) at 200-500 deg.C to provide (meth)acrylic acid and/or an ester thereof.
