    摘要： A process is disclosed for the solvent dewaxing of wax--containing hydrocarbon oils, preferably waxy petroleum oils most preferably waxy lubricating or transformer oils. The process employs methyl tertiary butyl ether (MTBE) as the dewaxing solvent, either alone or in combination with other dewaxing solvents such as ketones, halogenated hydrocarbon anti-solvents, and mixtures thereof. The use of MTBE as a dewaxing solvent, or in combination with conventional dewaxing anti-solvents permits lower volumes of solvent to be employed in the dewaxing process while simultaneously producing an oil of lower wax content and lower dewaxed oil pour point at the same filter temperature as that commonly employed using conventional dewaxing solvents. Dewaxed oil yields for equivalent pour point are 3 to 4% higher with the MTBE dewaxing process than with prior dewaxing processes.
