    • The dispersibility of soot in a lubricant formulation containing a dispersant is evaluated by (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 conditions 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 chromatography medium. The liquid mobile chromatography phase comprises a mixture of a liquid non-aromatic 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 the dispersant or dispersants that are also contained within the lubricant formulation.
    • 通过(a)制备炭黑在润滑剂配方中的分散体来评估烟灰在含有分散剂的润滑剂配方中的分散性; (b)将分散的炭黑样品从步骤(a)沉积到平面色谱介质上; (c)对(b)的样品进行色谱条件和(d)通过比较沿着色谱介质的预定位置处由于炭黑引起的变黑的浓度来评估炭黑的迁移程度。 液体移动层析相包括粘度和沸点低于润滑粘度油的液体非芳族烃部分的混合物; 以及包含润滑粘度的油和也包含在润滑剂配方中的分散剂或分散剂的油组分。
