The reductive alkylation of a French petroleum asphaltene (Lagrave) was studied with potassium in THF, in absence of an electron transfer reagent. From the number of butyl and benzyl groups added to the starting asphaltene, the difference of reactivity of the alkyl reagents, butyl iodide and benzyl
H and 13C n.m.r. spectra of asphaltenes separated from a heavy crude oil using n-pentane at different temperatures were measured. Average molecular parameters and hypothetical structural models for these asphaltenes were proposed using n.m.r. measurements, calculated molecular weight of unit sheets
