Hydrocarbon Autoxidation followed by using the Oxygen–Hydrocarbon Charge-transfer Spectrum
IT is well known that a solution of oxygen in an organic solvent produces a charge-transfer (CT) spectrum 1–6 , the intensity of which has in some cases been shown to be proportional to the oxygen concentration 2,4,6 . This spectrum is evidently “collisional” in origin, no stable complex being forme...

Zusammenfassung: | IT is well known that a solution of oxygen in an organic solvent produces a charge-transfer (CT) spectrum

, the intensity of which has in some cases been shown to be proportional to the oxygen concentration
2,4,6
. This spectrum is evidently “collisional” in origin, no stable complex being formed between oxygen and the organic compound

. We have followed the oxygen consumption in a hydrocarbon autoxidation by following the decay of the CT spectrum. The technique is less sensitive than the traditional measurement of oxygen absorption from the gas phase into a vigorously stirred or shaken solution
7,8
, but it has the advantage of being a simpler technique, measuring oxygen consumption in the solution directly and requiring small amounts of materials. |
