Gas-chromatographic studies of the products in a sealed TE CO<inf>2</inf>laser discharge

Abstract

In this investigation the degraded gas mixture in a sealed TE CO <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> laser discharge was analyzed gas-chromatographically, which enabled us to determine the concentration of CO accurately, even in the presence of large quantities of N <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> . According to the reversible decomposition reaction 2CO <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">\rightleftharpoons</tex> 2CO + O <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> , [CO]/2[O <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> ], which should be unity, was found to be noticeably more than unity. The deviation of the O <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> concentration from that needed to satisfy the CO <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> decomposition equation was more than 26 percent. No oxides of nitrogen were detected and the missing oxygen was recovered when the degraded gas mixture was heated to the dissociation temperature of ozone.
