Utilization of the frontal technique in reaction gas chromatography for the determination of functional groups

Functional group analysis

“…Azo Compounds. The azo function in a number of azobenzenes was determined by a selective oxidation of the azo group with H2Cr04 in sulfuric acid (43). The nitrogen produced was determined by gas chromatography.…”

“…The H2Cr04 oxidative procedure previously developed for azo compounds (43) has been adapted for the determination of hydrazine salts, arylhydrazines, and arylhydrazones (42).…”
