| Description |
The stru<!tureand composition of asphaltic materials present in three crude
oils produced from three reservoirs situated at Viraj, North Kadi. and Santhol in north
Gujarat region in western India have been studied using IR and HNMR spectroscopy.
The asphaltenic substances were obtained by Soxhlet extraction of the 200°C+ residue
of each crude oil with n-pentane. n-heptane, petroleum ether (40-60°C), and ethyl
acetate, following the standard IP 143/78 method. The variations in chemical nature
and composition of all solvent-insoluble asphaltenic components have been discussed.
All insolubles constitute mainly highly substituted aromatics having ether linkages,
ketone and pyrrolic N-H functions, and large number of methyl and methylene groups
in alkyl chain substituents.</textarea>
