It has unexpectedly been discovered that the distillate dewaxed index for viscosity (DDVI) value a feedstock be based at a specified pour point can predicted on • a) the feed distillate residual wax content at a temperature as E. `C detennined by Differential Scanning Calorimetry, such as the feed distillate residual wax content at a temperature cones - R p ponding to the specified pour point temperature; b) the feed distillate index; feed distillate kinematic refractive c) the vis - cosity at a temperature, such as kinematic viscosity at 100°C; and d) the distillate volume-averaged boiling point. Based on 40 this the VI feedstock unexpected correlation, potential of a * be determined based can on measurement of properties that * can be performed on a time scale corresponding to one or a ' 2 few days using a few milliliters of feedstock. • 0 1-1 Q 1 1-1 0 20 60 80 100 DDV Ca')-9C.
