    摘要: An absorption medium for deacidifying fluid streams which has improved oxidation stability includes at least one aliphatic amine, and at least one non-hydroquinoid antioxidant. The absorption medium may be employed in deacidifying a fluid stream, in particular an oxygen-containing fluid stream, when the fluid stream is brought into intimate contact with the absorption medium in at least one absorption step.
