CHEMILUMINESCENCE OF THE SODIUM OR SODIUM HALIDE CATALYZED OXIDATION OF CARBON MONOXIDE BY NITROUS OXIDE.
Abstract
At 550 - 600C in reaction vessels coated with sodium chloride or bromide and possessing temperature inequalities, the slow reaction of carbon monoxide and nitrous oxide is catalyzed by the alkali halide with simultaneous emission of the sodium resonance lines. The catalytic and luminescent reactions postulated are: Na + N2O to NaO + N2; NaO + CO to CO2 + Na* (Doublet-P); Na* to Na + photon. The formation of sodium atoms from sodium chloride or bromide probably occurs as NaX + O + CO to CO2 + NaX* to CO2 + Na + X; although this is less certain than is the subsequent course of the catalysis. The slow nitrous oxide, carbon monoxide reaction does not excite the metal lines in potassium chloride or sodium iodide coated vessels (potassium vapor does not undergo the analogous chemiluminescent catalytic cycle, and iodine is a reaction poison). It does, however, briefly excite the red lithium line in a lithium chloride coated vessel. (Author)
