Abstract: To provide a method of producing acrylic acid which enables low energy-consumption production of acrylic acid from glycerin mixtures including glycerin and one or more compound selected from the group consisting of fatty acids, fatty acid salts, glycerides, fatty acid esters, alkali compounds and alkali compound salts. The method of producing acrylic acid according to the present invention includes the steps of obtaining an acrolein mixture by causing a dehydration reaction to a glycerin mixture; and obtaining an acrylic acid mixture by causing an oxidation reaction to the acrolein mixture; and recovering acrylic acid from the acrylic acid mixture.

Abstract: Disclosed are an acrolein production method capable of producing acrolein from a glycerin mixture including either one or both of a fatty acid and a fatty acid salt, a glycerin; a fatty acid ester, and the like with a little consumption of energy, and an acrylic acid production method. Specifically disclosed is an acrolein production method having the steps of: dehydrating glycerin in the glycerin mixture to produce an acrolein mixture including acrolein; either one of a fatty acid and a fatty acid salt, and the like; and collecting acrolein from the acrolein mixture. Also specifically disclosed is an acrylic acid production method having the step of reacting acrolein produced by the acrolein production method with molecular oxygen.
