Patent ID: 8742169

Claim:
A method for producing acrolein, comprising step (1) of subjecting glycerol to dehydration reaction of glycerol 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 remaining after step (2); step (4) of treating part or all of the copper compound recovered in step (3) 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 step (4) to step (1), wherein the compound containing a heteroatom is at least one member selected from the group consisting of a sulfur-containing compound, an oxygen-containing compound and a nitrogen-containing compound, wherein the sulfur-containing compound is at least one member selected from the group consisting of sulfone, sulfoxide, sulfide and disulfide, wherein the oxygen-containing compound is at least one member selected from the group consisting of ether, carboxylic acid and ester, wherein the nitrogen-containing compound is at least one member selected from the group consisting of amine, amide and nitrile, and wherein the copper compound is at least one member selected from the group consisting of sulfate, pyrosulfate, phosphate, pyrophosphate, nitrate, carbonate, carboxylate, halogenated compound and oxide of copper.
