3 ml. of sample containing a trace of the fluorescent indicator was charged to the column. After the chromatographic zones were measured on the column, the nonfluorescent saturates zone up to the beginning of the yellow fluorescence was collected in a small vial for subsequent analysis by gas chromatography.The best procedure for hydrogenating the olefins employed an apparatus similar to that described by Mitchell et al. (10). A condenser, which was cooled by circulating water at a temperature of 1°C ., was placed between the reaction vessel and the gas buret.
