The molecular weights of asphaltenes, as determined by vapour-pressure osmometry, vary considerably and are dependent upon the nature of the solvent as well as the temperature. The data are interpreted in terms of association (of the asphaltene units) in solvents of low dielectric constant and disso

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
