| abstract | A method for evaluating the dispersibility of soot in a lubricant formulation comprising at least one dispersant comprises the steps of: (a) preparing a dispersion of carbon black in the lubricant formulation; (b) depositing a sample of the dispersed carbon black from step (a) onto a planar chromatography medium; (c) subjecting the sample of (b) to chromatographic condiÂtions and (d) evaluating the extent of migration of the carbon black by comparing the density of darkening due to carbon black at pre-defined locations along the chromaÂtography medium. The liquid mobile chromatography phase comprises a mixture of (i) a liquid hydrocarbon portion having viscosity and boiling point less than that of an oil of lubricating viscosity; and an oil component comprising an oil of lubricating viscosity and (ii) an oil component comprising an oil of lubricating viscosity and the dispersant or dispersants that are also contained within the lubricant formulation. Preferably, the oil component of the liquid mobile phase is a fully formulated diesel lubricant, and is identical to the oil sample in which the carbon black is dispersed. |
