Abstract

Hydrocarbon fluids are produced by hydrocracking a vacuum gas oil stream, fractionating and/or hydrogenating the hydrocracked vacuum gas oil. The fluids typically have ASTM D86 boiling point ranges within the range 100° C. to 400° C. the range being no more than 75° C., they also have a naphthenic content greater than 60%, the naphthenics containing polycyclic materials, an aromatic content below 2% and an aniline point below 100° C. The fluids are particularly useful as solvents, for printing inks, drilling fluids, metal working fluids and as silicone extenders.
