Abstract
1,153,116. Solvent-extracting oils. TEXACO DEVELOPMENT CORP. 7 Feb., 1968 [13 March, 1967], No. 6046/68. Heading C5E. A method of manufacturing a lubricating oil includes the steps of contacting a lubricating oil stock with a solvent comprising N-methyl- 2-pyrrolidone at a temperature of at least 50 F. and below the temperature of complete miscibility of said lubricating oil stock in N-methyl-2-pyrrolidone and at a dosage effective to dissolve at least 10% by volume of material from said lubricating oil stock whereby a refined lubricating oil stock is produced of improved viscosity index, improved thermal stability and improved oxidation stability. The process is applicable to paraffinic and naphthenic oils. Preferred temperatures are between 50 and 250 F. The process may be followed by de-waxing with toluene-MEK mixture and distillation.
