  • Uninhibited electrical insulating oil
    Publication number: 20070090016
    Abstract: An uninhibited electrical insulating oil is prepared by blending a severely hydrotreated naphthenic distillate base oil having a viscosity of from about 50 to about 80 SSU at 380° C. and an aniline point from about 63° to about 84° C. with a solvent extracted, non-hydrogenated paraffinic distillate having at least 9.0 wt. % aromatic content.
    Type: Application

  • Aromatic solvents having aliphatic properties and methods of preparation thereof
    Patent number: 5908548
    Abstract: An aromatic solvent together with methods for its preparation are described. A composition includes a paraffin fraction in an amount of from approximately 9 LV % to approximately 15 LV %; a naphthene fraction in an amount of from approximately 35 LV % to approximately 55 LV %; and an alkylbenzene fraction in an amount of from approximately 8 LV % to approximately 16 LV %. The solvent provides advantages in that the high solvency that is typical of an aromatic solvent is combined with a narrow distillation range, a high flash point and higher boiling range that is typical of an aliphatic solvent.
