The preparation of various isotopes

In addition to the foregoing, some examples may be given of cases in which other isotopes have been concentrated by distillation. 

The relative difference in mass and the relative natural abundance are particular favourable for separating the isotopes of carbon and chlorine  

In the distillation of CCl a double isotope separation, thus takes place. The separation factor of the system C is about 1.00013, corresponding to a difference 

Single and double isotope concentration by countercurrent distillation cli = effective number of stages 

P f Ps — vapour pressure of the substance with the light (1) and the heavy (p) isotopes at the distillation temperature (34.6 °C)

The preparation of various isotopically enriched acetylacetonate complexes of Li, Na, K, Be, Mg, Al, Cu and Pd have been des-cribed. Long-range coupling over two or three bonds are...
