Pyrolysis and gas chromatography of benzene clathrate
article
IN 1897, Hofmann and Küspert1published a paper in which they described that when benzene is added to a solution of nickel cyanide in aqueous ammonia and containing acetic acid, a precipitate of the composition [Ni(CN)2.NH3.C6H6] is formed. This compound, now known as benzene clathrate, was obtained with a slight change, using no glacial acetic acid, in the method described in ref. 2. The clathrate (referred to here as VM) on analysis gave: CCombining double low line 45.86 per cent, H Combining double low line 4.50 per cent, N Combining double low line 20.86 per cent, and Hofmann and Küspert found: C Combining double low line 45.07 per cent, H Combining double low line 4.20 per cent, N Combining double low line 20.37 per cent. The calculated analysis is: C Combining double low line 46.60 per cent, H Combining double low line 4.37 per cent, N Combining double low line 20.39 per cent. © 1962 Nature Publishing Group.
