AROMATIZED PRODUCT N-HEPTANE - CHARACTERIZATION BY GAS-CHROMATOGRAPHY

A high resolution gas chromatography method for the analysis of the ar omatised product of n-heptane has been developed. The individual aroma tics were separated on OV-101 and OV-275 capillary columns. The qualit ative analysis was done using correlation between Retention data vs, b oiling point and the literature data available. Quantitation was achie ved using flame ionisation detector assuming that the relative respons e for all aromatics is same. Packed column of OV-275 gave group type d istribution of saturate (1.2%), monoaromatics (76.6%) diaromatics 21.9 % and triaromatics 0.3%. Data generated are presented as individual co mponents, hydrocarbon groups and according to carbon number distributi on.
