Abstract
1,202,797. Deuterated hydrocarbons. C. E. FROSST & CO. 24 April, 1968 [29 April, 1967], No. 19393/68. Heading C5E. The invention comprises per se saturated C 10-36 perdeuterated cyclic and acyclic hydrocarbons having an isotopic purity in the range 95-99À7 atom per cent D. They are prepared by reacting a corresponding saturated or unsaturated hydrocarbon with deuterium gas, in the liquid phase and in the presence of a stationary catalyst, e.g. Pd/C, Pt/C or Rh/C. The following compounds are prepared from the corresponding saturated hydrocarbons: n-decane-d 22 , n-dodecane-d 26 , n-hexadecane-d 34 , n-octadecane-d 38 , n-tetracosane-d 50 , n-hexatriacontane-d 74 , 2,2,4,4,6,8,8-heptamethylnonaned 34 , pristane-d 4o , decalin-d 18 , cyclododecane-d 24 , n-octacosane-d 58 and squalane-d 62 . In addition, cyclododecane-d 24 is prepared by deuteration of 1,5,9-cyclododecatriene, and 1,2-dicyclohexylethane-d 26 by deuteration of trans-stilbene.
