✦ Synopsis

Hydrogen containing tritium was atomized at a hot tungsten filament, and the atoms were reacted with carbon (graphite, lamp black and diamond) at 77°K. At pressures low enough to allow a collision-free path for the hydrogen atoms between the filament and the surface of the carbon, CH,, CsH,, CsHs, iso-C,H,, n-C,Hr, were produced and an unidentified higher molecular weight compound was extracted by benzene from graphite. Only CHI and CrH, were formed with hydrogen atoms moderated to 77°K by an inert helium atmosphere. Graphite was more reactive than diamond or lamp black. The distribution of products was found to vary with filament temperature, hydrogen pressure and length of reaction time. A sequence of consecutive reactions is proposed as the mechanism for the formation of the hydrocarbons.
