Process for manufacturing naphthenic solvents and low aromatics mineral spirits

摘要

Naphthenic solvents and low aromatics mineral spirits are produced simultaneously by blending a hydrocarbon oil boiling in the range between about 100 DEG F. and about 600 DEG F. with an aromatics fraction having an initial boiling point similar to that of the oil to produce a blend containing in excess of about 10 weight percent aromatics, hydrogenating the blend in the presence of a hydrogenation catalyst until aromatics present in the blend have been converted into lower boiling naphthenic compounds, and thereafter fractionating the hydrogenated material to produce a highly naphthenic overhead fraction useful as a solvent and a low aromatics bottom fraction useful as mineral spirits.
