Rapid group analysis of straight-run petroleum cuts by liquid-adsorption chromatography (LAC) with automatic recording
- 13 Downloads
A method of quantitative group analysis has been developed for bicyclic aromatic hydrocarbons with a minimum content of these hydrocarbons (down to 0.2%) in kerosine and kerosine-gas oil distillates, and also for the analysis of monocyclic aromatic hydrocarbons in naphtha cuts, by a recording method of column liquid-adsorption chromatography (LAC) onγ-Al2O3 in a stream of n-hexane or petroleum ether. The analysis requires 20–25 min, and the chromatographic column can be used repeatedly.
