Haul, R.; Puttbach, E.: Diffusion von gelöstem Wasserstoff und Deuterium in flüssigem Ammoniak. In: Zeitschrift für Naturforschung - Section A Journal of Physical Sciences 24 (1969), Nr. 12, S. 1914-1922. DOI: https://doi.org/10.1515/zna-1969-1209
Diffusion coefficients of H2 and D2 in liquid NH3 were determined from rates of solution at constant partial pressure of the gases (9 atm) in the range -60 to + 1 0 °C. D0(H2) = 9.4±0.4 ; D0(D2) = 7.4+0.4 cm2/sec; ΔE(H2) =2090 ± 30 ; ΔE(D2) =2030 ± 30 cal/mole. The mechanism of diffusion and the isotope effects are discussed on the basis of the structure of liquid NH3 .
