3431.    TRAMM, -----., AND CLAR, -----.  [Preparation of Oils From Primary Products of the Gasoline Pressure Synthesis.]  FIAT Reel K29, frames 6,634-6,701, 1940-1941; PB 70,218; TOM Reel 296.

       Preparation of lubricating oils from gasolines of the pressure synthesis is described extensively.  Primary materials are gasolines, which have been prepared partly by Co and partly by Fe catalysts.  In any case, a preliminary treatment of the gasolines is necessary.  The best way is to conduct the gasoline vapor through hot concentrated phosphoric acid with following neutralization.  26 tables, 3 graphs.
