 1456.    ---------------.  [HOFMANN, U.] [Deposition of Carbon From Carbon Monoxide or Benzine in the Presence of Iron.  II.  Crystalline Carbon With High Adsorptive Power.]  Ber. Deut. Chem. Gesell., vol. 61, B, 1928, pp. 2183-2194; Chem. Abs., vol. 23, 1929, p. 751.

       C obtained from CO or benzine by the method previously described or precipitated in the presence of Fe(CO)5, although crystalline, is highly adsorptive.  The adsorptive power cannot be attributed to the presence of amorphous C.  It is due to a very loose, crystalline structure, presenting an enormous surface.
