Distillates (petroleum), solvent-dewaxed heavy paraffinic (10C)
Distillates, petroleum, solvent-dewaxed heavy paraffinic
A complex combination of hydrocarbons obtained by removal of normal paraffins from a petroleum fraction by solvent crystallization.  It consists predominantly of hydrocarbons having carbon numbers predominantly in the range of C20 through C50 and produces a finished oil with a viscosity not less than 100 SUS at 100.degree.F (19cSt at 40.degree.C).
