ABSTRACT:
Lubricants of improved characteristics are produced by carrying out a solvent extraction to remove aromatic components after solvent or catalytic dewaxing. Aromatic extraction solvents such as phenol, furfural or N-methyl pyrrolidone may be used. The process is particularly useful with wax-derived lubricants produced by the hydroisomerization of a petroleum wax which has then been dewaxed.
