Abstract (en)
[origin: EP0471461A2] High boiling high VI (viscosity index) wax isomerates and natural waxy oil distillates can be solvent dewaxed to low pour point under miscible conditions by combining said high boiling high VI stocks with from 5 to 50 LV% of a lower boiling conventional VI waxy lube oil and coprocessing the mixture under conventional solvent dewaxing conditions. The resultant low pour mixture can subsequently be fractionated into high yields of the high boiling high VI component and of the lower boiling, conventional VI component, both components exhibiting low pour points. <IMAGE>
