2982.     ---------------.  [RUHRCHEMIE, A.-G.]  [Hydrogenation of Carbon Monoxide by Addition of Acetylene in the Liquid Phase Under Pressure.]  FIAT Reel L-5, Oct. 7, 1941, frames 565-567; PB 70,159; TOM Reel 299.

        In the tests carried out under pressure in the liquid phase, heptane was used as the base material.  It was ascertained that low-pressure hydrogenation of CO by addition of C₂H₂ in the liquid phase is not favorable for the production of unsaturated O-containing compounds.  Comparative tests carried out under analogous conditions but with the addition of C₂H₂ in the gas phase show a considerable decline of the olefinic constituents in the gasolines thus produced.
