The lube stocks from West Siberian crudes are characterized by high contents of aromatic hydrocarbons and by high viscosity indexes of the naphthenic/paraffinic and aromatic hydrocarbons. Mass spectrometric analysis showed that isoparaffins account f

1. An analysis of methods for determining the purity of high-molecular-weight naphthenic-paraffinic hydrocarbons has shown that a method based on ultraviolet absorption spectra is the fastest and most sensitive. 2. In naphthenic-paraffinic hydrocarbo

This article investigates the aromatic hydrocarbons of a residual oil produced by selective solvent treatment from a base stock for lube oil production. Most of the resins and solid hydrocarbons were removed and liquid chromatography was used to sepa
