Microanalysis of reaction products in sealed tube wet air oxidations by capillary gas chromatography
Capillary gas chromatography can be used to analyze the reaction products of the oxidation of a compound in aqueous solution. A sealed glass capillary tube is used as the reaction vessel in which the compound and its products of oxidation are confined. The contents of the sealed tube are released upon crushing and are swept directly into the carrier gas stream of the gas chromatograph using a novel technique. As an example, the technique outlined in this paper is used to determine the combustion products of the wet air oxidation treatment of phenol; however, it may be used for any reaction in which volatile products are formed. A microanalysis technique is described which offers advantages over previously reported methods. The oxidation reaction at elevated pressure and temperature occurs in a sealed glass capillary tube and the reaction products are subsequently quantitatively introduced directly into a fused silica capillary column coated with a cross-linked polymer for gas chromatographic separation and analysis.
