Abstract (en)

[origin: WO2004033607A1] A heavy hydrocarbon composition with utility as a heavy hydrocarbon base stock comprising at least 95 wt.% paraffin molecules, of which at least 90 wt.% are isoparaffin, containing hydrocarbon molecules having consecutive numbers of carbon atoms, is a liquid at 100 °C, at which temperature its kinematic viscosity, as measured by ASTM D-445, is above 8 cSt, has an initial boiling point of least 850 °F (454 °C) and an end boiling point of at least 1000 °F (538 °C), wherein the branching index (BI), as measured by the percentage of methyl hydrogens, and the branching proximity (CH2>4), as measured by the percentage of recurring methylene carbons which are four or more carbon atoms removed from an end group or branch, of said isoparaffinic hydrocarbon molecules, are such that: (a) BI-0.5(CH2>4)<15; and (b) BI + 0.85(CH2>4)<45; as measured over the heavy hydrocarbon composition as a whole.
