2845. ----- [RUHRCHEMIE, A. G]. [Aldehydes.] German Patent 722,707, June, 1942 (Cl. 12 o-7.03). Chem. Abs., vol. 37, 1943, p. 5077.

Aldehydes are produced from ethylene or its homologs by oxidation with O₂-containing gases. The gaseous mixture flows in a circuit and is periodically and for short periods only heated to the reaction temperature of approximately 225°. The O₂ supply is periodically interrupted. Activated C is used as catalyst.
