Abstract

PURPOSE: To obtain the titled compound, by oxidizing acrolein with O2 in gaseous phase using a novel catalyst having high activity and high selectively comprising one or more elements selected from the group consisting of Mo, V, Cu, Fe, Mn, alkaline earth metal and Zn and oxygen as essential ingredients and P as an optional ingredient.
CONSTITUTION: In preparing acrylic acid by reacting acrolein with O2 or an O2- containing gas in gaseous phase, a catlyst obtained by adding one or more selected from alkaline earth metals and zinc and manganese, and optionally phosphorus to a system consisting of molybdenum, vanadium, copper, iron and oxygen is used. Especially preferably atom ratio of elements comprising the catalyst Mo:V:Cu:Fe: Mn:X (X is alkaline earth metal or Zn):P is 12:1W5:0.2W5:0.5W4:0.05W1:0.03W 1.5:0.03W1.5.
EFFECT: The life of a catalyst is economically long.
