Influence of Oxidation Products on the Chemiluminescent Oxidation of Tetrakis(Dimethylamino)Ethylene

摘要

Light emitted during the oxidation of tetrakis(dimethylamino)ethylene (TMAE) was found to be profoundly influenced by TMAE oxidation products and certain additives. Although the low-boiling oxidation products have no effect upon the emitted light, tetramethyl urea was found to be a major quencher. It was observed that only a fraction of the potential light, anticipated from dilution calculations, was emitted in 'normal' TMAE oxidation. Addition of TMAE nonsolvents such as water and dimethysulfoxide reduces the concentration of oxidation products and increases the light intensity; water further increased the light intensity by increasing the rate of reaction. Aliphatic hydrocarbons and dimethylsilicone fluids were found to be satisfactory nonENCHING DILUENTS. (Author)
