Definitions

  • a fraction boiling'above'fraction (b) which may be a distillate boiling at from 980 1070? F. TBP or'a residuum boilingatabove. 1070* F. (TBP).
  • the fraction (b) is solvent extracted with a solvent having preferential solubility for aromatics to produce a dewaxed oil-having a viscosity index 10 to 30 viscosity index units above the dewaxed oil viscosity index of the charge.
  • viscosity index or V.I. is determined by ASTM D2270).' The depth of this extraction generally is greater for lower V.I. charge stocks such as those having a V.I. of 30 to 60 than for charge higher V.I.
  • a process for the preparation of lube oils comprising fractionating a crude into a fraction (a) boiling principally at from about 720 F. to 855 F., a fraction (b) boiling principally at from about 855 F. to from 980 to 1070 F. and a fraction (c) boiling above fraction (b) solvent extracting fraction (b) with a solvent having a preferential solubility for aromatic compounds, combining this rafiinate with the other two fractions which frac- 7.
