A simple field test for the determination of cyclohexanone and methylcyclohexanone vapours in air

Abstract

A field method is described for determining either cyclohexanone or methylcyclohexanone vapour in air at concentrations up to 400 and 920 mg m^–3, respectively. The vapour of the ketone is collected in water and then coupled with the diazonium salt of H-acid. The two ketones form similar colours and the concentration of each can be determined by comparing the intensity of the colour produced with a series of permanent colour standards common to both. The procedure is simple and the time required for a complete analysis is about 25 minutes.
