This report describes a process for characterizing wax extracted from lubricant basestocks. The authors chose seven basestocks coming from different global regions and having a wide range of low-temperature properties. The wax was extracted from each basestock at-40{degrees}C using a cold-filtering method. Gas chromatography/mass spectroscopy (GC/MS), differential scanning calorimetry (DSC), thermal mechanical analysis (TMA), and optical microscopy (OM) were used to characterize these waxes. These data were compared to each basestock/s viscosity, pour point, and borderline pumping temperature, and some correlations were found between the wax characteristics and the cold temperature properties of the basestocks. This method of characterization can be useful when trying to select the optimal pour point depressant for engine lubricants. 10 refs., 24 figs., 5 tabs.
