Oxygen → Acrylic Acid

Temperature

280 °C

A stainless-steel reaction tube having an inner diameter of 10 mm and a length of 300 mm was filled with 5 ml of the above catalyst for oxidation reaction. A mixed gas containing 3 volume % of acrolein obtained in Example 1, 3 volume % of oxygen, 30 volume % of water vapor and 64 volume % of nitrogen was introduced into the reaction tube at a space velocity of 3000/hour. The reaction tube was heated to 280° C. in an electric furnace, thereby subjecting the mixed gas to oxidation reaction. The outlet of the reaction tube was cooled and the resulting reaction gas was condensed and collected. Gas chromatograph analysis of the collected liquid showed that the acrolein conversion was 98% and the acrylic acid yield on the basis of acrolein was 90%.
