Description |
A lubricating oil base stock, Inter Neutral type, boiling range 282-562°C, was
fractionated into three boiling ranges of 282-456, 456-492, and 492-562°C.
The waxes were isolated from the parent base stock and its fractions by
solvent dewaxing. Hydrocarbon-type constituents, i.e., saturates, naphthenic
aromatics, and polar aromatics, were separated by elution chromatography
and were characterised for their physical properties. The viscosity-temperature
behaviour of the base stock sample and its various fractions and components,
i.e., dewaxed oil, extracted waxes, saturates, naphthenic aromatics, and polar
aromatics, was determined and correlated with the composition. It was found
that the concentration, nature, and type of hydrocarbon components present
greatly influenced the physical properties as well as the viscosity-temperature
behaviour. The average chain lengths of the waxes obtained by IH NMR
match well with those determined by gas chromatography. Copyright @2006
