1. Quenching of chemiluminescence by molecular oxygen was detected in reactions of low-temperature oxidation of propionaldehyde and acetaldehyde, diethyl ether, hexane, and in the oxidative decomposition of di-tert-butyl peroxide. In these reactions, the luminescing particles are excited formaldehyde molecules. 2. From an analysis of the dependence of the chemiluminescence intensity on the oxygen concentration, the lower limit of the lifetime of excited molecules of formaldehyde was estimated, τ > (0.7-1.3) · 10-6 sec. © 1966 Consultants Bureau.
