Title:
アクロレイン及び/又はアクリル酸の製造方法
Document Type and Number:
Japanese Patent JP2004503517
Kind Code:
A
Abstract:
Acrolein and acrylic acid are produced from propane and propene by absorption/desorption of propane and propene from a gas mixture followed by oxidation, in which no heterogeneously catalyzed dehydrogenation of propane occurs between the desorption and oxidation stages without addition of oxygen. Acrolein and acrylic acid are produced from propane and propene by: (a) separation of propane and propene from a gas mixture (A) by absorption in an absorption medium; (b) separation of propane and propene from the absorbent to give a mixture (B) containing propane and propene; and (c) using mixture (B) for oxidation to the required product(s). In this process, no catalytic dehydrogenation of propane without the addition of oxygen is carried out between stages (b) and (c).
