Patent
·
OSTI ID:7209287
A process for dewaxing oil by mixing the oil with a liquid dewaxing agent having a high solvent power for the oily components of the wax-bearing oil but low solubility for its waxy components, chilling the resulting mixture to precipitate waxy components and separating the precipitated material from the oil-containing solution is characterized by the use as the dewaxing agent of a mixture comprising a partially hydrogenated naphthalene and a selective solvent having a low solvent power for oil.
