摘要

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.
