    Abstract: The present invention relates to a method for producing acrolein, comprising step (1) of subjecting glycerol to dehydration reaction in the presence of a copper compound and a compound containing a heteroatom; step (2) of recovering acrolein generated in the dehydration reaction step (1); step (3) of recovering part or all of the copper compound which remained after the recovery of acrolein; step (4) of treating part or all of the recovered copper compound with at least one member selected from a group consisting of an oxidizing agent and acid; and step (5) of returning part or all of the copper compound treated in the above step to step (1); and a method for producing acrylic acid, comprising reacting acrolein obtained by the above method with molecular oxygen. The production method of the present invention enables efficient production of acrolein and acrylic acid from glycerol contained in plant oil and animal fats derived from carbon dioxide in air without depending on the oxidation of propylene derived from fossil resources.
